Note:
For a fully configured system, we recommend that you
use a power supply unit (PSU) that complies with ATX 12V
Specification 2.0 (or later) and provides a min. power of
330W.
We recommend that you use a PSU with 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.
