FSP Twins 500W Redundant ATX Power Supply Review
Peter Donnell / 7 years ago
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).
At 500W this unit isn’t the most powerful. However, keep in mind it does house two 500W units for stability, rather than more power. The peak is 571.8; a respectable 13.39% above the rated value.
