Asus E2938 manual Power supply requirements, Usb Pci

•For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12V 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.
