Epilogue
The Deepcool PX1000P achieves a high overall performance thanks to its tight load regulation (although there is room for improvement at 3.3V), the good ripple suppression, the excellent transient response of the 12V rail at both normal loads and the ATX v3.x ones, the long enough hold-up time, the low vampire power, and the high enough efficiency.
The areas that could be improved are the protection features where lower OCP triggering points are required under hot conditions on all rails and the fan speed profile, which needs a complete overhaul. An average noise output of 32.5-33 dBA is too loud for this category’s standards, and the fact that the PPSU’sfan starts at over 30 dBA when the semi-passive operations end will surely be annoying for the majority of users. Since this unit uses a semi-digital platform, implementing a digital interface wouldn’t be costly. It will allow users to tune the fan speed profile, given that the appropriate application was developed and offered. However, most users don’t want to have an extra thing to do: tune the PSU’s fan speed profile, so it would be ideal if the default one were set appropriately to allow for the lowest possible noise output.
The Deepcool PX1000P is not affordable at $240, but it uses an expensive platform featuring digital controllers, high-end capacitors, and quality FETs. If 1000W are not enough for you, you could look at the PX1300P, which costs 60 dollars more. If you plan on powering a super-expensive RTX 4080 or RTX 4090, you should not cheap out on the power supply but choose one that will easily handle the task.
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

It’s such a shame that such a good and expensive PSU is hampered by a silly fan profile.
This figure looks like some sort of torture device.
I want to ask, if the starting 1k RPM (30-35dBA) is the same even with the semi-passive mode turned off?… If so, than it is really silly.
