Real World Test System & Observations


We started with our test system, which is an ASUS Zenith Extreme Alpha running 32GB of RAM and a 2990WX CPU for maximum power pull. We then proceeded to add one card at a time to assess noise and performance as the load grew. With the three cards you see here, and we observed an input of 1023W with the bench running both CPU and GPU based render loading to keep the PSU fully loaded with a real-world workload. The load was between 1023 - 1037W depending on the clock rate and thermals of cards, which caused a minor (less than1% fluctuation) during testing.

The Hydro G PRO passed this with no issues whatsoever, so we went a bit unconventional to push the PSU just a bit further.


Since our Zenith board does not have quad double spaced slots, we had to improvise a bit here. We used the riser from our Phanteks case review. It has a cushioning foam, we then laid an extra 1080 Ti GPU across the top to give us four GPUs to work with for more loading. This time wattage jumped to 1135W with peaked into the 1154W range as GPUs adjusted their clocks based on their boost algorithm.

The exhaust of the Hydro G PRO was toasty at this point, reaching a peak of 52C with an ambient of 24.8C. This is not ideal as components wear more quickly as they are warmer, but we are pushing this PSU to a load that most people would opt for a 1500W+ to support. The Hydro G PRO performed admirably and kept chugging along without a single issue or hang up on our workloads. The Hydro G PRO ran for over 2 hours at this loading without any problems, which for me is more than a pass.
