ASUS P3-P5G31

• For a fully configured system, we recommend that you use a power supply

unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)

and provides a minimum power of 400 W.

• Do not forget to connect the 4-pin ATX12V power plug; otherwise, the

system will not boot.

• Use of a PSU with a higher power output is recommended when

configuring a system with more power-consuming devices. The system

may become unstable or may not boot up if the power is inadequate.

• The ATX 12 V Specification 2.0-compliant (400W) PSU has been tested to

support the motherboard power requirements.

11. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)

These connectors are for ATX power supply plugs. The power supply plugs

are designed to fit these connectors in only one orientation. Find the proper

orientation and push down firmly until the connectors completely fit.
