These connectors are for an 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.
• Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot.
• When using two graphics cards, do not forget to connect the 4-pin
ATX +12 V power plug to the EZ Plug™; otherwise, the system will
be unstable. See page 6-6 for details.
• Use of a power supply unit (PSU) with a higher power output is
recommended when configuring a system with more power-
consuming devices. The system may become unstable or may not
boot up if the power is inadequate.
• Make sure that your PSU can provide at least the minimum power
required by your system. See the table below for details.
