9. ATX power connectors (24-pin EATXPW, 4-pin ATX12V)
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.
• Use of an ATX 12 V Specication 2.0 -compliant power supply unit (PSU)
that provides a minimum power of 350 W is recommended for a fully-
congured system.
• Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the
system will not boot up.
• Use of a PSU with a higher power output is recommended 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.
