ASUS M4A78T-E 2-33
Chapter 2
• 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 600 W.
• Do not forget to connect the 4-pin ATX +12 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.

11. ATX power connectors (24-pin EATXPWR; 4-pin ATX12V)
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.
