Rosewill Glacier 600W Gaming 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).
OK what the bloody hell is going on here? That’s right, this unit pulled over 50% more than its 600W rating before the OPP kicked in and shut it down. What’s crazy is that we actually got 947W on our first three runs! We repeated the test after we ran all other load tests to get some heat into the unit and tried again, and that’s when we got the 907W score, so you’ll have no problems with power draw spikes here.
