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.
• The ATX 12 V 350 W Spec. 2.0 PSU passed the motherboard power
requirement test with the following configuration:
CPU : Intel
®
Pentium
®
4 3.6 GHz
Memory : 512 MB DDR2 (x 4)
Grpahics 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)
• You must install a PSU with a higher power rating if you intend to
install additional devices.
