Epilogue
The Deepcool PX850G achieves high overall performance, close to other PSUs that use the same CWT platform. In noise output, the non-restrictive fan grille, and the not aggressive fan speed profile, allow for a low enough average noise, which stays below 30 dBA, which I have set as the baseline for quiet operating PSUs. The dead silent PSUs don’t exceed 20 dBA average noise.
The Deepcool PX850G currently costs 160 dollars, which is notably higher than the Thermaltake Toughpower GF3 with similar capacity. Thermaltake’s unit achieves similar performance and has about the same average noise output, so you can easily go with TT’s offering if you don’t want to pay more money. There is also the Montech Titan Gold 850W, which is sold at a similar price and achieves the best performance, my sample at least, among all CWT CSZ platforms that I tested. Moreover, depending on the voltage input, the Montech unit’s average noise output is notably lower at 24-25 dBA.

Hello, i’m trying to choose between Deepcool PX850G, MSI MPG A850G and Asus rog strix 850w gold aura. Leaning towards Asus, but it is ~70$ more expensive than MSI and Deepcool. Which one is the best and which one is the worst? Which should i choose between MSI and Deepcool?
Deepcool has problems recently, don’t know if their PSUs will supported under DeepCool’s name, so better go for the MSI unit.
it turns out there is no point in buying Deepcool PX850G white? I am choosing a power supply for a white assembly and wanted this model in white
Did you notice any coil whine with this PSU? I bought a Corsair Rm850x and it has a slight steam whistle type noise even while idle.
coil whine is super weird, it depends on your hardware configuration
Oops I meant the Rm850e.
Is coil whine generally common amongst most PSUs? I noticed that the capacitors on the Rm850e are non-japanese, could that be a contributing factor?
Thank you
in general for me, since I have lots of test systems, coil whine has to do mostly with the graphics card in use and the current use (e.g. game menu or desktop)
typically coil whine has to do with the other system parts, too, not only the PSU.
