OPP923.69W (123.16%)
OTPNo (tried up to 150°C @ secondary side)
SCP12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes
PWR_OKOperates properly
NLOYes
SIPSurge: MOV Inrush: NTC Thermistor & Bypass Relay

The OCP triggering points on the minor rails are set quite high, and the same goes for 5VSB. Unfortunately, that rail cannot handle such high loads, so its ripple gets out of control. On the other hand, OPP is set at a reasonable level.

As you can see from the table above, we tried hard but failed to find any evidence of OTP. At least SCP is present on all rails and the power-good signal is accurate. We have to admit, though, the lack of OTP is a big let-down for us.
