Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1,500 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.
Load Regulation Charts
Efficiency Chart
Efficiency is between 90 and 95 percent for quite a large region of this PSU's operational range.

Infrared Images
Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera, which delivers 320 x 240 IR resolution (76,800 pixels).
During the full power and overload tests we noticed that with the ambient temperature close to 48 C (118.4 F) the bridge rectifier's operating temperature exceeded 100 C (212 F). There is no need to worry about this, though, since all good quality bridge rectifiers can easily handle such high temperatures and, besides that, the higher the temperature of a bridge rectifier, the lower the energy losses it experiences.

laviniuc you mean P2, right?Reply
"This means that we will most likely see an EVGA SuperNOVA 550 T2 unit in the near future." -
envy14tpe The 650W version sells for $85usd (here in Taiwan) and 750W for $100. Not sure why this company doesn't sell more internationally since it is at the top tier. As it is known for quality. Gonna be picking up a SuperFlower PSU with my next build.Reply -
casey_souder actually it did and still says that 10C is 50F.
A change of 1 degree C equals a 1.8 degree F change. Google is doing a temperature conversion, not a unit conversion. -
Roj Number 1 Yes, 10C = 50F, but a 10C increase in temperature is a 18F increase in temp. Two different things.Reply
