Chapter 1
• 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.
• DO NOT forget to connect the 8-pin EATX12V power plug. Otherwise, the system will
not boot.
• 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 PCI Express x16 cards, use a PSU with
1000W power or above to ensure the system stability.
10. Speaker connector (4-pin SPEAKER)
The 4-pin connector is for the chassis-mounted system warning speaker. The speaker
allows you hear system beeps and warnings.
9. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to fit these connectors in only one orientation. Find the proper orientation and
push down firmly until the connectors completely fit.
