Thermaltake Toughpower DPS G 1200W PSU Review

Thermaltake introduced the Toughpower DPS G Platinum line that consists of three new, semi-digital and fully modular PSUs made by Enhance Electronics. The highest-capacity 1200W model is our test subject in today's review.

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

Efficiency Chart

The efficiency sweet spot is between 150W and around 880W, where you can expect readings between 90 to 95 percent.

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).

The PSU's internal temperatures are fairly normal. The bridge rectifiers operate at around 93 degrees C with the PSU delivering full load for a prolonged period. This temperature level isn't a problem for the GBU15L06 rectifiers; combined they can handle up to 30A of current at 115 degrees C.
