For a fully con gured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Speci cation 2.0 (or later version) and provides a
minimum power of 350 W.
DO NOT forget to connect the 8-pin EATX12V power plug. Otherwise, the system will
not boot.
We recommend that you use a PSU with a higher power output 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.
If you want to use two or more high-end PCI Express x16 cards, use a PSU with
1000W power or above to ensure the system stability.

These connectors are for ATX power supply plugs. The power supply plugs are
