ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
Correctly orient the ATX power supply plugs into these connectors and push down
rmly until the connectors completely t.
• For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12V Specication 2.0 (or later version) and provides
a minimum power of 350 W. This PSU type has 24-pin and 8-pin power plugs.
• DO NOT forget to connect the 8-pin EATX +12V power plug. Otherwise, the system
will not boot up.
• We recommend that you use a PSU with higher power output when conguring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
