0W Load Tests

These charts show how much power each PSU draws when no load is applied (i.e. the leakage), both when the PSU is switched on and when it's off.

Noise Levels

These charts show each PSU's noise levels at three different load levels. Note that for the highest one we allow things to run for 20 minutes before taking a measurement, as we feel this is a more realistic simulation of user experience with heavy loads, such as gaming.

Update 04/12/14: Please note that we originally reported the EVGA SuperNova P2 1200W and Seasonic Platinum Series 1200W as reaching noise levels of 48.6 and 42.9 dB(A) in the 500W load test, respectively. We have since realised that these results were incorrect, and in fact the EVGA PSU remained at just 18.8 dB(A) during this test while the Seasonic reached 21.7 dB(A). We sincerely apologise for these inadvertently misleading errors, and have updated the appropriate graph, reviews, scores and conclusion in line with the new data. Please note that in light of this new data we now consider the EVGA SuperNova P2 1200W to be deserving of our Premium Grade award.
