Protection Features

Check out our PSUs 101 article to learn more about PSU protection features. Our protection features evaluation methodology is described in detail here.

Protection Features

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

OCP on the minor rails is set properly, while at 5VSB it's a bit higher. The OPP triggering point is fairly aggressive. However, given a properly-configured OTP, we don't worry about the high OPP level.

You get SCP on every rail, the power-good signal is accurate, and surge/inrush current protection are taken care of.
