supply are designed to fit these connectors in only one orientation. Find the
proper orientation and push down firmly until the connectors completely fit.
Important notes on the motherboard power requirements
•
Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the
system will not boot up.
•
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.
•
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.
