Deepcool PQ1200G ATX v3.1 PSU Review

Deepcool PQ1200G is an ATX v3.1 power supply with enough power to support a gaming system with an RTX 4090. It uses a platform provided by Helly Technology, and for the moment it will be only available in the Chinese market, but into this year it will also be released worldwide. 

The Deepcool PQ1200G will be included in my best ATX v3.x & PCIe 5.x PSU picks article.

Deepcool keeps on releasing new PSU models and I am more than happy to evaluate them! Although it already has two ATX v3.1 1000W and 1200W models in its portfolio, the PN1000M and PN1200M, which use CWT’s omnipresent CSZ platform, it decided to release the PQ-G series, which has four members, including two members with 1000W and 1200W capacities. All PQ-G members use Helly platforms. Helly Technology looks to get stronger as time passes by and this is good since the more competitors, the better the products. For the moment, the PQ-G will be only available in the Chinese market, but soon enough, Deepcool will offer them to the rest of the world at attractive prices, as I heard.
