Asus P5KPL-E - Manual (Page 47)

ASUS P5KPL-E 1-35
• 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.
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.
