5.2Power Supply Guidelines

AMD Opteron processor-based motherboards may be designed to leverage industry standard power supplies. The selection of the proper system-power supply is a critical element to the success of the finished system. For best results, a system builder should always contact the motherboard, power supply, and chassis suppliers or vendors to verify that each of the chosen components supports the desired system configuration, and a system builder should verify that support through internal testing and validation.

5.2.1Server and Workstation Platform Power Supplies

Depending on the motherboard vendors’ design requirements, the server/workstation can use either an ATX 12-V power supply, or an EPS12V. The motherboard design can use one or two power connectors. Usually a separate power connector is used to provide power for the I/O components. It is important that you confirm with the motherboard manufacturer the exact connector requirements.

Note: It is imperative that system builders ensure that the power supply of choice and the selected chassis are mechanically compatible.
