Power supply plug in definition

HP Common Slot Power Supplies are designed to simplify the serviceability and maintenance of power supplies across the HP portfolio of server and storage products by being hot-swappable and providing a tool-less installation. Multiple power management options deliver greater power efficiency when using redundant power supplies to reduce overall power usage. Multiple input and output options deliver increased flexibility in usage while reducing the chances of creating "trapped" power capacity in the data center. HP Common Slot Power Supplies have Titanium level certification by both the 80Plus program and the EPRI providing the highest level of power efficiency (up to 96%) in the IT industry.
Note: Information published at this site may refer to products, programs or services that are not available in your country. Computer power supply units (PSU) deliver the power to the PC hardware via a number of cables with connectors. Standard ATX power supplies typically have the main power connector P1, additional 12V connectors, as well as peripheral, floppy drive, serial ATA, and PCI ExpressA® receptacles, which we will describe below. Under normal operation, PS_ON# is activated when you press and release the computer power button while it is in standby mode.


Also note that many brands such as Apple's Power Mac, Dell (during certain years), Compaq and HP used proprietary boards with entirely different pin designations- see this for info on some brand name power supplies. All voltages are referenced to the same common (if you need to measure any voltage, connect the return lead of your voltmeter to any of the COM contacts). When the industry began using voltage regulation modules (VRM) running off 12V2 to energize CPU and other motherboard components, the bulk of the wattage shifted to 12 volt buss.
Some units may also have an optional 2x3 socket that can be used for auxiliary functions, such as fan monitoring and control, IEEE-1394 power source, and a remote sense of 3.3 V. HP Common Slot Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HP server and storage solutions. Consult your local HP business contact for information regarding the products, programs and services that may be available. Their generic specifications for various desktop systems are defined in Intel's design guides, which are periodically revised. Most of today's motherboards supply their CPU with a separate 12 volt cable, which has 4 pins for ATX style (sometimes called P4) or 8 or more pins for EPS and non-standard high-power systems.


The power supplies provide the IT industry’s highest level of power efficiency (up to 96%), helping users to reduce power requirements per server and reducing overall data center power requirements.The Platinum Plus and Titanium power supplies also enable HP Power Discovery Services which focus on increasing compute density while reducing data center outages. Prices, promotions, specifications and availability are applicable to Singapore only and may change without prior notice. Accordingly, different ATX-style PSU may use different number of power wires: see the pinout diagram to the right. Despite our best efforts, a small number of items may contain pricing, typography, or photography errors. Well, under certain conditions a new PSU can still be used with an old PC and vise versa- see our guide on connecting 20-pin PSU to 24-pin motherboard.
