be quiet! Pure Power 10 600W 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).

The use of quality capacitors is clear here, with the 600W unit able to draw 674W before the OPP kicked in and shut it down. At more than 10% over the official rating, this is impressive, so there shouldn’t be any concern about power draw spikes from your components.
