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 6-5 for details.
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. See the table below
for details.
