Corsair RMi Series RM650i Fully-Modular 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).

This may be a 650W unit, but we managed to get it just shy of 800W before the OPP kicked in! While not ideal to run it this hard all the time, it’s good to know that if you do get a spike in your power requirements, your system shouldn’t skip a beat.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
