Chapter 1: Product introduction

6. ATX power connectors

(24-pin EATXPWR and 4-pin ATX12V)
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.

• Do not forget to connect the 4-pin ATX +12 V power plug;

otherwise, the system will not boot.

• Use of a 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 power supply unit (PSU) can provide at least

the minimum power required by your system.

• If you intent to use a PSU with 20-pin and 4-pin power plugs, make

sure that the 20-pin power plug can provide at least 15A on +12V

and that the PSU has a minimum power rating of 350 W. The

system may become unstable or may not boot up if the power is

inadequate.
