Deepcool PX1300P ATX v3.x PSU Review

The Deepcool PX1300P is a high-end power supply, suitable for supporting the strongest graphics cards available in today’s market, either from NVIDIA or AMD. Thanks to its native 12VHPWR cables, set for 600W max power each, it is future proof to support the upcoming GPU generations and as about its ATX v3.0 official compatibility, read the full review to understand why this is not an issue. 

The Deepcool PX1300P is included in my best ATX v3.x & PCIe 5.x PSU picks article.

The PX1300P is an ATX v3.0 PSU, but before you rule it out from your list, you should look at the article below:

For those of you who didn’t bother checking the article above, I will mention one thing only. This PSU can be ATX v3.1 compatible with a different 12+4 pin header on its modular panel, which doesn’t cost anything extra! The high-power cable connecting the PSU to the graphics card remains the same, regardless of the PCB header, 12VHPWR (ATX v3.0) or 12V-2×6 (ATX v3.1).

One strange fact about the PX1300P is that it has two 12VHPWR cables, one of which takes power from a pair of 8-pin sockets. Thanks to this feature, this PSU satisfies the ATX v3.1 specs! The whole situation is a bit crazy, I know, to have a new ATX spec version based on a new header, creating all this confusion among manufacturers, brands, and users.

Leaving aside ATX compatibility, the PX1300P is a powerful PSU that can support any of the current and upcoming GPUs. Despite its high power, it has compact dimensions and uses CWT’s advanced CTT platform. This is a popular platform, and it is also used in the XPG Cybercore II 1300 and the MSI MEG Ai1300P units. CWT claimed a big part of today’s PSU market since it was among the first to offer high-performance and reliable ATX v3.0 platforms.

  1. Wanna thank you guys for the review, I was doing an absolute ton of research a couple of weeks ago between 1000+ watt ATX 3.0 units, and between this and the PlatiGemini I ended up with this unit cause it had more PCIE, a longer warranty and was actually on sale for 270 US at time of purchase.

    One thing I wanted to ask, is there a way to check if my native 12VHPWR cables are 12V-2×6? Anything to look for in the sense pins or the connector itself? I’d appreciate it cause all this crap around 12VHPWR is very confusing lol
