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).

Another impressive result, with the unit showing it was capable of drawing 35%+ more power ran the rated specification before the OPP kicked in and powered down the unit. This is good news, as it means that power spikes when your gaming are unlikely to cause the system to power down.
