XFX Pro850W Black Edition Fully Modular 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).

This unit just keeps on knocking our tests out of the park, we managed a whopping 1192.0W before the OPP stepped in and shut the unit down .
