If you look at the current price comparison, the M12 power supplies from Seasonic still range at a level from 130 to 150 €, a price for which we already get more efficient models.
We picked this power supply randomly from the existing range of the first devices, not that anyone gets the idea that we got a Gold sample. The sturdy packaging reveals a familiar sight, which unfortunately also applies to the amount of extras, because just like Seasonic, Silver Power does not provide such useful freebies like cable ties. The powder finish does not win a beauty prize, but serves its purpose and fairly well protects the PSU against gross motor skills.
Recesses in form of a grid at the front end minimise the air resistance of the waste heat of the PSU, which supports the effect of the fan.
The cabinet opening for the main wiring harness is equipped with an opulently designed edge protection, so that the edges can not mistreat the cables, this measure should become popular.
The Silver Power PSU has connector ports embedded in the casing, so that they do not protrude beyond the power supply case.
In spite of that cable management enjoys the highest popularity, even if it results in no technical advantage, only in generally higher prices. The cable lengths are amply dimensioned, but could be slightly longer, because in large towers 55 cm long cables can be too short, especially if the power supply has to be assembled on the case's bottom. Despite the thorough cable coating the cable strands are extremely flexible; this applies especially to the wonderful ribbon cables. In the article linked above you can also learn everything about DC-to-DC technology, which indeed plays a major role in the case of Silver Power SP-SS750M. All four boards are made of epoxy resin impregnated glass fibre mats, which means they belong to the high quality class FR5 in contrast to the much cheaper Pertinax boards FR1 to FR3. For the input filter (including board) X (1x) and Y capacitors (2x) are connected, which are supported by a filter coil. Last but not least the shrink tubes on the important solderings must not be missing; it is a very important contribution to the internal power supply security. Of course the circuit board for the implemented protective circuits is also not missing, but you have to be careful there, because not every PSU that speaks of OCP, OVP, etc. Also the Silver Power PSU already meets the requirements of the RoHS environmental ordinance ("Restriction of the use of certain Hazardous Substances in electrical and electronic equipment"), which came into effect in July 2006. Exchanging the PSU is not very difficult, even unpractised users should not encounter great difficulties; therefore we do not describe the procedure in detail, and name only the important aspects. Before the installation of a PSU and respectively before the test we briefly check its function with a Power Supply Tester. The Power Good Value (PG) specifies the space of time in which the motherboard and the PSU "talk to each other" during the power on of the system. The article is also very detailed; we test our power supplies like this since February 2010, so we spare you the story here. Not much is missing for the 80 + gold certification (Gold: 87, 90 and 87 per cent at 20, 50 and 100 % load with 115 Volt) the Silver Power PSU even operates a bit better than the Seasonic M12D original, although the layout has not been changed significantly. Concerning the PFC values the Silver Power is also very good, this applies to the measured temperatures too, we also controlled them via the sensor on the heat sinks. Neither had we noticed unusual electronic noises which exceeded the typical quiet cracking noise under full load during the test in the test station nor in our current Socket 1336 system. First launched in December 2008 Seasonic's technology proved to be pathbreaking and it still does not have to hide in March 2010. The Silver Power Gorilla SP-SS750M PSU has excellent efficiency levels, a steadfast stability and brilliant Ripple & Noise values, there is no changing that. In the next weeks and months we are going to test some more power supply units, including the current and upcoming models with 80+ Gold certificate. Power supplies are an often overlooked part of your computer, however the health of your power supply is an extremely important concern.
Whenever you upgrade your system or build a new system with an old power supply, you should always check the power supply to make sure . Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application.
In addition to the power supply the box also contains a power cord, mounting screws, wire ties, Corsair case badge, Corsair Link USB dongle, a multi-language User’s Manual and a black nylon pouch containing 19 modular cables.
Lee and or PCPER I am a bit confused about the PSU test bench as described in this article.
Which tests are you using the PC-based load for and which tests are you using simulated loads for ?
Additionally, testing in open air versus mounted in a warm PC chassis, typically pushed against a wall or under a desk.
The PCPerspective PSU test bench uses a combination of six Progammable DC loads and up to three different banks of precision load resistors to create the various loads (up to 2,000W max). Early in the millennium, there was a TV channel called ZDTV (which changed to TechTV in late 2000).
Hosted by geeks Leo Laporte and Patrick Norton, the show covered a broad swath of the enthusiast PC world including gaming, modding, hacking (Digg founder and tea aficionado Kevin Rose started out as a guest hacker, then the resident hacker, and eventually became a co-host), programming, etc.
It was during the call-in section of the show that a caller asked for advice in purchasing a power supply. That was about a decade ago, and though I have since owned at least 25 different power supplies, with several of them considered some of the best on the market, deep in the recesses of my consciousness, I've always wanted to try a PC Power and Cooling PSU. Today I will be looking at what is the latest version of PC Power & Cooling's most popular power supply, the 750 watt Silencer Mk II.
Here, we elaborate on the concepts and requirements for HTPC cases that were mentioned only briefly at the outset of this chapter. Your authors are somewhat split on the subject of form factor as it pertains to case orientation and layout.
The vented surface area should match the exhaust outlet surface area as closely as possible.
The internal layout of the case should be free of significant obstructions and should leave ample room for air to circulate and flow through following an effective cooling path across the heat-producing components?the CPU, video card, and hard drives. Fan mounts should be at least 80 x 80 mm (a more or less standard PC fan size), and provide at least 25 mm of vertical clearance. Use noise (or lack of noise) as an important selection criterion when picking components for an HTPC.
Make sure that what noise is produced must travel a long way to arrive at a listener’s ears.
If you recognize potential sources of noise and take steps to prevent sound from propagating (by isolation or insulation) you’ll be able to reduce their impact on your listening experience as much as possible.
As long as a case is sturdy, and tightly enough fitted to eliminate as much vibration or resonance in its outer panels as possible, it should do the job. Some HTPC (and other) cases may come with sound dampening materials already installed, or offer extra-cost sound dampening kits (Uneed claims to offer such a kit for the x15e, but we can’t find any for sale). This is where aesthetics come into play, and that’s something that only a buyer can really appreciate in context. Te following table mentions numerous vendors who offer PC cases designed specifically for HTPC use.
It was expected that the existing Gorilla family would eventually spawn a new member because the high-end segment still was missing in the portfolio. We already hinted at it in the Sharkoon Rush Power test, that we will not get involved in this game and that we will again and again anonymously purchase models from the current series. Well, this is not the end of the world but in this price segment some extras would be appreciated. The overall depth of 160mm should be no problem for smaller computer cases; we are still well within the ATX specifications. Silver Power refrains from counterproductive rear or side vents which makes sense, because in the worst case warm air from the inside of our PC could enter. The weight that our calibrated scale shows is nothing unusual today, with 2364 grams the Gorilla power supply is at about the level of comparable power supplies of these ratings.
Unfortunately those fans are relatively rare in current power supply layouts, except from Seasonic nearly no manufacturer uses them.


Not only because the individual cable strands are long enough, also the flat ribbon coating of the strands is flexible, so that the individual strands can be excellently placed within the computer case. The locking position of the connectors is clearly defined and we get an audible feedback in order to hear that the plug has arrived in the port. The additional circuit boards and connectors not only have significantly higher production and additional costs, but also might involve the risk of corrosion-voltage drops.
Occasionally you read the call for a completely modular wiring arrangement, so that the main wiring harness may be removed. The quality of the plugs and shielding is at a high level, we could not find a stubborn plug during our test. The corresponding extra-board sits slightly hidden under the heat sinks, but Seasonic was as kind as to give us a separate copy on which we can see the polymer aluminium capacitors very well. FR4 and FR5 boards have better creep resistance and improved high frequency characteristics. But that is not all; the input filtering is continued on the main board and consists of two additional X-capacitors, two other Y-capacitors, a metal oxide varistor (MOV), the mandatory safety fuse and three coils along with an additional ferrite core.
The electrolytic capacitors of the secondary areas are also made by Nippon Chemicon and are available in 105 ° C variants and the grade KZH and KZE, which means even higher quality than the KMR capacitors of the primary circuit. For those who are surprised about the plastic films on the sides, these films serve to protect against the hull, preventing effectively from short-circuits. A separate advertisement of this characteristic does not help in merchandising anymore; the manufacturers have to comply with it. The most important basic rule when working inside the computer casing is to set all the components to zero-voltage. The Loudness of the fan is measured about 15 cm away from the fan with an ACR-264-verified plus instrument, which usually includes a range from 15 to 140 dBA. The ripple and noise results are excellent and free of any incident of bursts or peaks, showing clearly that all the filtering units work very well. The Sanyo Denki fan clearly is one of the better models on the market and the S2FC fan control keeps it well under control.
But there might be Socket 1156 systems that react with noise to DC-to-DC PSUs, so far turning off the power options in the BIOS could help. If you look objectively at the market you will see which products are labelled as "seminal" and you will shake your head.
Up to 60% load it works very quietly and it comes with a high class fan, which is by no means a matter of course among that price category. Especially because this PSU would also be suitable for workstation motherboards with more than one CPU. Insofar it will become interesting, because high efficiency levels are not the only quality criteria for a current PSU, even if the manufacturers would like to tell us just this over and over again.
It’s also good to check in once and a while to see if your power supply is still running your system well or needs replacing. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS Platinum efficiency, and clean, stable power. Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a Corsair Commander (available separately).
As we tackle these subjects head-on, we hope to teach you how to evaluate cases for yourself (or to look in published reviews for the rights kinds of information, should they be available). In the most important sense, PC cases relate to those motherboard form factors they can accommodate. The various ATX specifications are designed so that smaller variants of the same family (such as mini-ATX or micro-ATX) can be mounted in cases that support larger variants (full-scale ATX, in this scenario). One of us believes that tower cases can be okay for HTPCs, providing they meet other criteria and don’t look too out of place in the living room.
Smaller, more crowded cases invariably run hotter than larger, roomier cases even with identical components installed.
That’s a primary contributor to our earlier observation that a roomier case runs cooler than a more crowded one.
Larger 120 mm fans are preferable, because bigger fans can run more slowly yet move the same amount of air as smaller fans that run faster. HTPCs are involved in producing sound, either by itself for music, or in tandem with images for TV or DVD playback. This explains why drives are at the front of most horizontal HTPC cases and exhaust fans blow out the back: sound must travel from the drives through the case, out the back, then around to the front and out the entertainment center to be heard.
The best HTPC cases (and modifications) drill out drive mount holes, so that rubber or silicon grommets may be inserted into those larger holes. For example, many system builders apply noise-dampening materials inside case panels for sound insulation. For example, the Uneed case toured earlier in this chapter uses a heavy 8 mm aluminum front panel along with light 3 mm aluminum panels on the rest of the case (top, bottom, sides, and rear). Other vendors such as Acousti Products offer aftermarket products like their AcoustiPack soundproofing materials that diligent HTPC users can install in their own PCs (be prepared to spend $50–100 to do the job right).
Make sure what you buy matches your other AV components (or at least doesn’t clash with them too much). This is now remedied; the approximately one year old but still excellent layouts of the Seasonic M12 series which at least pointed out an efficiency of nearly 90%, even if these values already have been outperformed, provide the basis. Hopefully we will be able to figure this out in this test, but we can already reveal that the power supply will be offered directly after the CeBIT fair for 119 € and it includes a revised wiring harness that differs markedly from the rather stubborn Seasonic pendants. All the more pleasing is the sight of the modular cable strands which are in no way inferior to the ribbon cables from Corsair and Thermaltake, but more on that later. The weight might play no role at first glance, but there are still enough PC towers, where the retainers for the PSU already bend when unpacking the power supply. Experts in this field will agree on that, since this type of modular flat ribbon coating is also used by Corsair and Thermaltake.
To be honest, we can not understand that, because without a main harness a power supply will not work. There is also nothing to complain about the PATA plug connection, because also the six 4-pin Molex connectors with their handy removing aid still have a right to exist. Maybe some users will miss a tacho sensor and temperature-controlled connectors, but we have to tell them that those are often a source for problems, because there are many motherboards that refuse to work at a fan rotation speed of 1.000 rpm. The hotspots of the Mosfets are routed through heat sinks to the cantilevered aluminum radiator to ensure rapid heat dissipation. The whole design is substantially more complex than in cheaper power supplies, where this area is designed significantly more economical, before the current is then transmitted to the rectifier. On the board for the cable management we find some Nippon Chemicon capacitors that match the quality level of KY. There are quite a few manufacturers that leave out those circuits, even if the brochures tell a different story. As for the voltage stability, there is also no cause for criticism; the same applies to the tolerance levels of each power rail. Not until 50 to 60% load it reaches the magical threshold of 20dBA, under full load it works with 2200 rpm and produces up to 32,5 dBA excess pressure, which is of course not quiet. Finally we mention the standby power consumption (S5, computer switched off), which is at about 0,64 Watts, an excellent value.
Of course the current 80+ Gold PSUs are a bit better which is quite clear, nonetheless verifiable technologies are not to be characterised as out of the question. Silver Power significantly beats the Seasonic M12D not only in the expected price structure but first and foremost in the modular cabling system which clearly differs qualitatively from the Seasonic original.
Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options. But the term can also be used to describe case orientation and layout, which allows us to distinguish towers by a vertical orientation, and horizontal or cube cases by a horizontal layout. The other believes that only horizontal or cube cases make sense for entertainment center furniture.
That’s partly because smaller cases leave less space in which air can circulate, and partly because smaller cases build up and retain heat better than bigger ones do.


Both music and multimedia use sound dynamics for effect, so that sometimes things are deliberately quiet and other times things are deliberately loud. The basic idea is to eliminate all unnecessary noise, and to limit all necessary noise to an affordable or practical minimum. Although it’s commonly believed that foam damping can increase temperature levels inside your case, this is generally true only if you end up blocking airflow with the material, so proceed carefully. Though some experts argue that steel is preferable to aluminum for HTPC cases, aluminum’s lighter weight and greater ductility make it attractive to case builders.
It also incorporates two steel drive bay cages in the front of the case, and a steel expansion card and motherboard port block cage at the rear of the case.
Additional sound dampening is a good idea, provided you buy dense, high-quality materials (but keep them away from sources of intense heat like CPUs, GPUs, and Northbridge or Southbridge processors—or rather, away from their coolers or heat sinks). But appearance is a characteristic you’ll want to consider when selecting any HTPC case for purchase. If someone has to connect three case fans and his fan control, usually the first four Molex connectors are occupied. Although the fins are relatively wide, but since DC-to-DC power supplies are working very efficiently and are therefore not so warm, the airflow should be sufficient. They are joined by a large transformer on the main supply and a smaller one for the required 5V standby line that powers our USB devices for example.
We would have preferred the Zalman solution that provides higher quality polymer aluminum capacitors there, since this area is hidden, leak detection is extremely difficult, not to mention the difficult cooling of this area altogether.
But the motives for this are quite clear, the protective circuits have negative effects on the efficiency of a PSU and because they can only advertise well with high efficiency, they cheat. But the computer is not yet set to zero-voltage completely, because on the motherboard and inside the PSU there are still charged capacitors. On the other hand this probably will not bother those who operate a PSU on the brim of its rating, because within that range of performance other system components pipe up as well. Form factor can even be used as a metric of roominess, in that some cases qualify as compact or cramped, while others qualify as bigger and less crowded.
But happily both of us do agree that horizontal cases are probably the best choice for most HTPCs. It’s also true that installation and upgrades are easier in a roomier case because your hands and fingers have more room to maneuver as well. The Silverstone LC-04 you toured earlier in this chapter suffered somewhat from a ratio of vents to exhausts that favored vents, resulting in less than optimal case ventilation.
Fans should also be placed to push or pull air over the hottest components (that’s why faster CPUs require dedicated fans and coolers). When things get quiet, nobody wants to hear a PC grinding, buzzing, or whirring away in the background, distracting viewers or listeners from their programming material. If a case sits on a shelf in a home entertainment center, it may work better to apply sound insulation only to the front half of a panel, rather than covering the whole thing. Most commercial HTPC case designs use an aluminum shell around a steel cage or steel drive bays and card cages.
But because all mechanical connections between panels are tightly screwed together and fit extremely well, this case produces only a little vibration or resonant noise. We found little or no difference between going with standard black or silver cases ourselves, probably because our AV setups already include a mix of black and silver elements. If there is a water cooling system added, it increases the need for further connectors; ergo we see no reason for rationalising these plugs which some manufacturers already do. The aesthetes among us will certainly not praise the milling works of Seasonic, but it is not so bad, as long as the heat sinks serve its purpose. The soldering quality is at a very high level, there is absolutely nothing to complain about it. All other coils, X and Y capacitors and metal oxide varistors come from the usual upscale assortment in Japan.
Foolow along with Jonathan as he shows you his step by step guide to checking your PSU's voltage readings. Since we at HardwareLogic always want the most accurate numbers, my special assistant Bobby and I are going to teach you how to do it with a multimeter. That’s why we try to be clear about which meaning applies when we invoke this term in talking about HTPC cases. Of course, one of the joys of building your own HTPC is that you can choose whatever type of case (or other components) that you like best.
Mainly because smaller cases run hotter than larger ones, we urge you to go bigger rather than smaller when picking an HTPC case (or buying a pre-fab HTPC system for that matter). When it comes to an HTPC silent operation is the ideal, and as quiet as possible a very real goal that HTPC builders should seek to attain.
The back half is further away, so sound must travel further to your ears, and with drives typically front mounted, insulation near the source does the most good.
Those who’ve been more single-minded in their color schemes will want to pick an HTPC case that matches. Only when the PSU is hosed and kills all the components you get an idea of what went wrong. Under normal conditions the Power Good Value is between 100 and 500ms, which also was the case concerning the Silver Power PSU with 223.7 ms. Using a multimeter will give you the most accurate numbers while using software will give you numbers that will be off. Some cases are built with double walls because of noise insulation between inner and outer walls. Using a small trick you can get rid of the remaining electricity: Simply press the power on button of the computer again, after the cable has been removed. The 5v and 3.3v rail generally power devices like your motherboard, and its onboard peripherals. Many new motherboards draw from this line as well.I have one more thing to go through before we start. That means that you have to take extreme caution or you may wind up shocked and on your ass.
HardwareLogic and I cannot be held responsible for anything that happens to you, others, or your system. The digital multimeter I will be using reads out to two decimal points.If you plan to get load voltage readings it is strongly advised to download a stress testing program such as Prime95 before shutting down your system.
To gaurentee that your power supply can run your system it is necessary that you run it all full load to maximize power consumption. The system draws its main power through here, therefore you will get the most accurate numbers. Make sure your system is turned off.Take the multimeter and put the black rod into any of the grounds.
Depending on which rail you want to test, you can put the red rod in either the Orange, Red, or Yellow wires.
Boot up the system and make sure none of them get loose and fall out, the results could be disastrous.
To get an idle voltage, leave your system idle for a minute or two then check the multimeter readout.
To get a reading, put the black probe into either of the grounds and the red probe into whichever rail you want to test.
Using this method you can accurately measure your voltages and determine whether your PSU is capable of running your system or not.
