Important notes on the Motherboard Power Requirements
z Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot up.
z To power the motherboard, it is recommended that you use an
ATX 12 V Specification 2.0 power supply unit (PSU) with a
minimum 350 W power rating. This PSU type has a 24-pin and
4-pin ATX power plugs.
z If you intend to use a PSU with a 20-pin and 4-pin power plugs,
make sure that the 20-pin power plug can provide at least 15A on
+12 V and that the PSU has a minimum power rating of 350 W.
The system may become unstable or may not boot up if the
power is inadequate. We do not, however, recommend the use of
a 20-pin PSU.
