Chapter 1: Product Introduction
Ch apt er 1
• For a fully conſ gured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Speciſ cation 2.0 (or later version) and provides a
minimum power of 350 W.
• Do not forget to connect the 8-pin EATX12 V power plug. Otherwise, the system will
not boot.
• We recommend that you use a PSU with a higher power output when conſ 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 PCIe x16 cards, use a PSU with 1000W
power or above to ensure the system stability.
