Closer Look and Performance
The Interior of the PSU looks exceptional, as usual in the case of Deepcool power supplies. The build quality is high, and everything is clean. Soldering is also pretty good, and the whole design suggests there were no problems with overheating of any component.
The PSU can work up to around 30% load passively, so at least at about 300W. If we watch videos, browse the web, or do any regular office work, then the PSU will stay silent.
All the visible capacitors are rated at 100°C or more. Many, if not all, capacitors are Japanese, as we can read in the main features. Two main capacitors are made by Nichicon and are rated at 420V, 470uF, and 105°C, so exactly as the specs say.
There are not many heatsinks, and their surface is enough to keep everything cool and quiet. The fan keeps the optimal temperature under load, even though it runs in a semi-passive mode.
The PX1000G 1000W uses a fluid dynamic bearing Hong Hua HA13525H12SF-Z fan, rated at 12V 0.50A and up to 2300RPM. The automatic adjustment limits it much lower as we can barely hear it during even high load. During the tests, the fan was quiet, and the generated noise suggests it was spinning below 1000RPM during the highest load of our test PC.
Performance
Tests were performed on the AMD Ryzen platform, which contains the overclocked Ryzen 9 7950X CPU, ASUS Crosshair X670E Gene motherboard, overclocked Colorful RTX4080 Advanced OC graphics card, and additional components to bump the wattage some more. The peak wattage is around 800W.
All results were performed in the Corsair 5000D case with good airflow.
There were no stability issues during all tests. The efficiency of the PX1000G is great. The +12V voltage was nearly perfect under load. Everything else was also close to the reference values.
No wonder the PSU is certified 80 PLUS Gold and Cybernetics Platinum.
In idle and during the mixed load tests, the PSU was silent. Under full load, we could hear the fan, but it was still very quiet. Experience is better than on most competitive PSUs. It also proves that Deepcool had no problems with the design and its heat, so it could limit the PSUs fan a lot from its reference speed and still keep everything perfectly stable.
The mixed load test will be the closest to the daily usage, which is about what we can expect during less demanding gaming or some more demanding office tasks. During this work, the PSU is just perfect. It’s quiet and delivers stable voltages.
The PSU is designed to work with the latest graphics cards from Nvidia and AMD. However, the main difference makes the power connector used in new Nvidia graphics cards. The 12VHPWR cable used by Deepcool is designed to handle 600W and has 16 pins, so it matches high Nvidia series specifications like the RTX4080/90. In the tests, we used RTX4080, so maybe not the highest, but much more popular (due to its lower price) and also a power-hungry GPU.
The PX1000G is a refreshed version of the already widely awarded PSU, so it’s not a surprise we have no problems with recommending it to any gamer or power user. Enthusiasts and modders will for sure pick the new series because of its unique aesthetics, but also multiple additional features.
