•

Use of an ATX 12 V Specification 2.0-compliant power supply unit
(PSU) that provides a minimum power of 350 W is recommended
for a fully-configured system.

•

Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot up.

•

We recommend that you use a PSU with higher power output when
configuring a system with more power-consuming devices. The
system may become unstable or may not boot up if the power is
inadequate.

•

If you intend to use a PSU with 20-pin and 4-pin power plugs, make
sure that the 20-pin power plug can provide at least 15 A 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. The 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

•

You must install a PSU with a higher power rating if you intend to
install additional devices.
