Rosewill Quark 1000 Power Supply Review

Today we take a look at Rosewill's Quark 1000. In addition to 80 PLUS Platinum efficiency and fully modular cabling, this $200 unit can support multiple GPUs.

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 1000 possible 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.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU as it was being tested using our modified FLIR E4 camera that delivers a 320x240 IR resolution (76,800 pixels).
