Deepcool PX1000P ATX v3.x PSU Review

The Deepcool PX1000P is a strong, high-performance PSU, following the ATX v3.0 spec, meaning that it comes with a 12VHPWR connector, which can deliver up to 600W of power. This makes it compatible with all current generation graphics-cards, even the mighty Nvidia RTX 4090. 

The Deepcool PX1000P is included in my best ATX v3.x & PCIe 5.x PSU picks article.

The PX1000P 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).

Contrary to the PX1300P, which comes with two 12VHPWR cables, the PX1000P has one, which is the right choice given its capacity. The corresponding 12VHPWR connector is set at 600W maximum power output, although according to Intel’s specifications, it should be lower, at 450W. Nonetheless, most brands and manufacturers don’t follow this rule but provide 600W 12VHPWR and 12V-2×6 connectors to their PSUs.

The PX1000P uses the same platform as its large brother, which CWT provides (codename: CTT). This popular platform is also used in the XPG Cybercore II 1300 and the MSI MEG Ai1300P units.

One thought on “Deepcool PX1000P ATX v3.x PSU Review

  1. 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.
