Corsair HX750i Fully Modular Platinum Power Supply Review

Over Power Protection and Max Wattage

Power supplies often quote as having various protection mechanisms such and the most important of these is Over Power Protection. In our testing we crank up the power draw until the power supply either shuts down (meaning the OPP mechanism is present and working) or blows up (meaning it is either not present or not working). We then note the maximum power consumption before the power supply shut down (or blew up).

Very good OPP protection, as we managed to push over 950W through this unit before it shut down, so you should be able to handle the odd power spike when benchmarking or gaming without any major issue. Also, the OPP kicked in, preventing the unit from exploding, that’s always a welcome feature.
