• 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.
• We recommend that you use a PSU with a higher power output 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 PCIe x16 cards, use a PSU with 1000W
power or above to ensure the system stability.
• DO NOT connect the 4-pin power plug only, the motherboard may overheat under
heavy usage.
• Ensure to connect the 8-pin power plug, or both the 8-pin and 4-pin power plugs.
