• 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 400 W.
• Do not forget to connect the 4-pin ATX12V 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 or when you
intend to install additional devices. The system may become unstable or
may not boot up if the power is inadequate.
4.. Digital.audio.connector.(4-1.pin.SPDIF_OUT)
This connector is for an additional Sony/Philips Digital Interface (S/PDIF)
port. Connect the S/PDIF Out module cable to this connector, then install the
module to a slot opening at the back of the system chassis.
