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).
Again, another fantastic result for this unit, as we managed to pull over 250W extra power from it before the OPP kicked in; more than enough to deal with any big power spikes.
