11. ATX power connectors
(24-pin EATXPWR; 8-pin EATX12V; 4-pin EZ_PLUG)
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.
• 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 350 W.
• Do not forget to connect the 8-pin EATX12 V 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.
• 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.

• 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.
