Antec HCG1000 Extreme 1000W PSU Review: Good Looks For $150

Cross-Load Tests & 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 are calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. The ambient temperature is between at 30°C (86°F) to 32°C (89.6°F).

Load Regulation Charts

Efficiency Chart

There was a small region where efficiency landed between 92 and 94%. You typically don't see that from 80 PLUS Gold-rated PSUs. It's more common in Platinum-rated models.

Infrared Images

We apply half-load for 10 minutes with the PSU's top cover and cooling fan removed before taking photos with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

Temperatures inside of the PSU remained under 90°C during our 10-minute half-load test session.
