Make sure that your ATX 12V power supply can provide 8A on the
+12V lead and at least 1A on the +5-volt standby lead (+5VSB).
The minimum recommended wattage is 300W or 350W for a fully
configured system. The system may become unstable and may
experience difficulty powering up if the power supply is inadequate.
Please donʼt forget to connect with 4-pin ATX +12V power plug
supply, or system will not startup.
