ASUS Z97-A/USB 3.1

1-29

• 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 350 W.

• DO NOT forget to connect the 4-pin/8-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 or when you intend to install additional

devices. The system may become unstable or may not boot up if the power is

inadequate.

• If you want to use two or more high-end PCI Express x16 cards, use a PSU with

1000W 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.aspx?SLanguage=en-us for details.

4. 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.
