Asus M3A79-T Deluxe - Manual (Page 57)

ASUS M3A79-T Deluxe 2-31
• 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.
• 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.
• Do not forget to connect the 8-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.
11. ATX power connectors (24-pin EATXPWR; 8-pin EATX12V)
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.
