Chieftec SFX 500GD-C 500w 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).

OPP performance was ok, giving 16% more power before the unit cut out. This is ok if you get a small power spike from time to time while gaming, but the PSU won’t let you push it very far for long.
