Asus P5QPL-VM EPU - Manual (Page 39)

ASUS P5QPL-VM EPU 1-29
• For a fully configured system, we recommend that you use a power supply unit (PSU)
that complies with ATX 12V Specification 2.0 (or later version) and provides a minimum
power of 400W.
• DO NOT forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not
boot.
• We recommend that you use a PSU with a higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
10. 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.
