Asus P5QL - Manual (Page 53)

ASUS P5QL 2-31
• 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 EATX12V 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 with the following
configuration:
CPU: Intel ® Pentium ® Extreme 3.73GHz
Memory: 512 MB DDR2 (x4)
Graphics card: ASUS EAX1900XT
Parallel ATA device: IDE hard disk drive
Serial ATA device: SATA hard disk drive (x2)
Optical drive: DVD-RW
11. ATX power connectors (24-pin EATXPWR, 4-pin EATX12V)
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.
