Asus F2A85-M Computer Hardware User Manual


 
ASUS F2A85-M
1-27
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 300 W.
DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will
not boot up.
We recommend that you use a PSU with higher power output 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 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.aspx?SLanguage=en-us for details.
3. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
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.
