8. ATX power connectors (24-pin EATXPWR; 8-pin EATX12V_1; 4-pin EATX12V_2)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to t these connectors in only one orientation. Find the proper orientation and
push down rmly until the connectors completely t.
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 connect both the 8-pin and 4-pin power
plugs.
For a fully con gured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12V Speci cation 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 con 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 PCI Express x16 cards, use a PSU with
1000W power or above to ensure the system stability.
