PWR_OKOperates properly
SIPSurge: MOV Inrush: NTC thermistor & bypass relay

This PSU includes all of the protection features we'd expect, though OCP's triggering points on the minor rails and 5VSB are set pretty high.

OPP is configured at normal levels, while OTP is set quite high because this PSU includes a semi-passive mode. The power-good signal is accurate, and we observe surge and inrush current protection, both of which are expected from modern PSUs.
