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 550 W.
Do not forget to connect the 4-pin/8pin EATX12V 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.
If you want to use two high-end PCI Express x16 cards, use a PSU with
500 W to 600 W power or above to ensure the system stability.
