Corsair RM750x PSU Review: Improving On A Classic

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

The OCP triggering points are set high on every rail. Meanwhile, the RM750x delivers almost 975W before its over-power protection feature intervenes. Over-temperature protection is also set high.

Finally, we did observe short circuit protection on all of the rails, and the power-good signal proved accurate.

    I bought one last year and did not realize that I would need two EPS cables for future builds. Moved to EVGA. Corsair was too late.
