Methodology

Testing power supplies is a bit of a mine field, as many sites – like our own – test rail voltages to measure stability and tightness to the ideal rail rating. For a multitude of reasons these are imperfect tests. That said, without several tens of thousands of pounds worth of equipment, it’s not possible to accurately measure PSU ratings.

With that in mind, we still use our multimeter rail test during idle and load states to give something; if at least a real world comparison between units. It’s not perfect, and we would ask our readers to not base your PSU purchase solely on this review, but hopefully we can give some measure of comparing units. If not, then at least you know these units are capable of running out test setup for a prolonged period of time; or not.

The software used to load the PC was Prime95 (Large FFTs), and the 3Dmark benchmark running at full tilt to load the GPU.
