It is recommended that you use an ATX 12 V Specification
2.0-compliant power supply unit (PSU) with a minimum of 350 W
power rating. This PSU type has 24-pin and 4-pin power plugs.
If you intent to use a PSU with 20-pin and 4-pin power plugs, make
sure that the 20-pin power plug can provide at least 15A on +12V
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.
Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot up.
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.
