Seasonic Focus Plus Platinum 750 PSU Review: Efficiency On A Budget

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.

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

Seasonic's over-power protection (OPP) is set high. Normally it should be configured to trip at around 120%. Over-current protection (OCP) at 5V and 3.3V is set at normal levels, whereas it's quite high at 5VSB.

Finally, we observe short circuit protection on every rail, the power-good signal is accurate, and surge/inrush current protection are accounted for.
