IMBM-Q67A 2-16
IMPORTANT:
• For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)
and provides a minimum power of 350 W.
• DO NOT forget to connect the 4-pin / 8-pin ATX +12V 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.
2. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs
are designed to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit.
