DeepCool PN650M ATX v3.1 PSU Review

Epilogue

The DeepCool PN650M ATX v3.1 uses a tested CWT platform, with codename GPX, which has a bit lower overall performance than the CSZ platform used by many ATX v3.x compatible PSUs nowadays. Like the other family models, at the time of the review, I couldn’t spot this PSU on Amazon; I only found it in another much smaller shop at a pretty stiff price (above 100 dollars). Considering the not-so-high performance, the PN650M has to be sold at around 80-85 dollars to be competitive. I know that ATX v3.x compliant PSUs are notably more expensive than previous generation models, but I hope this will eventually change once the production grows. With AI coming strong, demanding for multiple GPUs to perform optimally, powerful and highly tolerant to power spikes PSUs will be required, which will offer a tremendous boost to ATX v3.x compatible models.

Competition

There are few 650W offerings compatible with the ATX v3.0 and v3.1 standards, mainly because most brands focus on 750W and stronger PSUs. This is why I was forced to include three older-generation models in my charts. At the time of the review, the only ATX v3.x 650W units I could find on Amazon were the Thermaltake Toughpower GF A3 650W and the Thermaltake Smart BM3 650W. I have the first in my charts but not the second since I have had trouble establishing communication with Thermaltake recently. The best ATX v3.x 650W unit is the XPG Core Reactor II 650, but I am unsure when stock will be available.

The PN650M doesn’t register a top performance in the 650W category, but it keeps its 12V rail high enough to not create any issues for the rest of the hardware, even with a 200% load. Speaking about ATX v3.x transient response performance, I should state that the 450W setting of the 12V-2×6 connector is overkill in a 650W PSU. Typically, it should be 300W.

DeepCool and CWT should remove the completely unnecessary 12V rail from this platform. If shorted, it can also kill this specific PSU. We tried two samples, and both died during the 12V Short Circuit Protection evaluation testing.

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.
