IMPORTANT:
• For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)
and provides a minimum power of 350 W.
• DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the
system will not boot up.
• We recommend that you use a PSU with higher power output 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.
1. ATX power connectors (24-pin EATXPWR, 4-pin EATX12V)
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.
