Asus P5Q-E Computer Hardware User Manual


 
ASUS P5Q-E Series 2-37
12. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs
are designed to t these connectors in only one orientation. Find the proper
orientation and push down rmly until the connectors completely t.
For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)
and provides a minimum power of 400 W.
Do not forget to connect the 8-pin EATX12V power plug; otherwise, the
system will not boot.
Use of a PSU with a higher power output is recommended when
conguring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
If you want to use two high-end PCI Express x16 cards, use a PSU with
500W to 600W power or above to ensure the system stability.
If you are uncertain about the minimum power supply requirement for your
system, refer to the Recommended Power Supply Wattage Calculator
at http://support.asus.com/PowerSupplyCalculator/PSCalculator.
