Fractal Design Integra M 550W 80Plus Bronze 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).

For a unit of this size, I was expecting it to cap out somewhere in the low 600’s, but much to my surprise, this unit was able to pull a mighty 774W before the OPP kicked in. This is great news for gamers, as those big power spikes shouldn’t result in your system shutting down and let you keep the action going.
