Thermaltake Toughpower DPS G RGB 850W PSU Review

In addition to its flagship Titanium line, Thermaltake also equipped the DPS G Gold family with an RGB fan. The highest-capacity model outputting up to 850W is our test subject today.

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 25,000 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 (12 V, 5 V and 3.3 V) as point zero.

Efficiency Chart

The unit's efficiency falls within the 90-92% region from around 160 to 590W, with load on the minor rails staying lower than 75W. This is a decent performance, but definitely not a top-notch one. And in this price segment, the competition is ruthless.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

Temperatures inside of the PSU are low given the conditions and loads that we apply.
