• For a fully congured system, we recommend that you use a power supply unit (PSU)

that complies with ATX 12 V Specication 2.3 and provides a minimum power of 350W.

• Do not forget to connect the 4-pin/8-pin EATX12 V power plug; otherwise, the system

will not boot.

• Use of a PSU with a higher power output is recommended 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 are uncertain about the minimum power supply requirement for your system,

refer to the Recommended Power Supply Wattage Calculator at

for details.

10. Speaker connector (4- pin SPEAKER)
