ATX power connectors (24-pin ATXPOWER and 4-pin ATX_CPU)

These connectors are for ATX power supply plugs. The power supply plugs are

designed to t these connectors in only one orientation. Find the proper orientation

and push down rmly until the connectors completely t.

OTE: Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the

system will not boot.

NOTE: Use of a PSU with a higher power output is recommended when

conguring a system with more power-consuming devices. The system may

become unstable or may not boot up if the power is inadequate.

NOTE: Make sure that your power supply unit (PSU) can provide at least the

minimum power required by your system.

NOTE:

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.

NOTE: You must install a PSU with a higher power rating if you intend to install

additional devices.
