Before you power on the system, please make sure that both ATXPWR1 and ATXPWR2 connectors
have been plugged-in.

Insufficient power supplied to the system may result in instability or the peripherals not functioning
properly. Use of a PSU with a higher power output is recommended when configuring a system with
more power-consuming devices.
