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 450 W.
Do not forget to connect the 4-pin/8-pin EATX12 V power plug; otherwise, the system
will not boot.
Connect the 4-pin EZ_PLUG power plugs to ensure sufficient power supply when you
install multiple graphics cards.
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.
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.
If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at
