These connectors are for an ATX power supply. The plugs from the
power supply are designed to fit these connectors in only one
orientation. Find the proper orientation and push down firmly until the
connectors completely fit.
•
It is recommended that you use an ATX 12 V Specification
2.0-compliant power supply unit (PSU) with a minimum of 300 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 300 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.
• The ATX 12 V Specification 2.0-compliant PSU passed the
motherboard power requirement test with the following
configuration:
CPU : Intel

4 3.6 GHz
Memory : 512 MB DDR (x 4)
Graphics card : PCI Express x16 Nvidia EN5900
Parallel ATA devices: IDE hard disk drive (x 2)
Serial ATA device : SATA hard disk drive
Optical drives : CD-ROM (x 2)
