The 8-pin Power Plug LED lights up to indicate that the 8-pin power plug is not
connected.
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. This PSU type has 24-pin and 8-pin power plugs.
We recommend that you use a PSU with higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
