Corsair Teases Liquid-cooled Power Supply Prototype

[btarunr]

Corsair at the 2025 International CES launched a couple of updates to its PSU lineup, the 2025 HXi series, and the 2025 RMe series, and you can read all about them here. Something else caught our eye at the Corsair booth, an unnamed, unlabeled PSU with a coolant tube from a DIY liquid cooling loop going in. It turns out that Corsair is dabbling with liquid-cooled high-wattage PSUs that can stay completely fanless, even under load. The PSU passes the coolant through an array of heatsinks that make contact with the hottest components, such as the switching MOSFETs, Schottky diodes, APFC, IGBTs, etc. Corsair is still deciding on whether to release this as an actual product. Tell them what you think in the comments.

I love wacky stuff like this.

Hopefully it's better than FSP's version; which just added a small cooling block to the existing heatsinks and only slightly improved performance between air-only and air+liquid-cooled, but not enough to warrant the upgrade and cost.

.....as with anything water cooled.....its not a mater of if....but when.....so... a dramatic future is instore for any who dare this journey......

So at this point every single piece of a computer can be liquid cooled at this point (Im ignoring mineral oil haha). Imagine a setup with every single piece liquid cooled!

I don't mind liquid cooled GPU,CPU,memory or SSD.

But PSU going to be a hard pass for me.

 

[goldman]

why would you water cool the thing that is the most dangerous and at the same time is one of the less cooling-dependant parts of your pc?

Modern aircraft has liquid cooled power electronics. On top of that the liquid is fuel. There is nothing wrong with the concept.

I would inset this into my existing system, with no kickback. I asked a PSU maker years about this, and the shared what they shared.

GPU power cables and connectors included.

Yeah, but modern aircraft are not built and maintained by the typical Corsair customer. Hopefully.

No thanks.

Corsair's Watercooling division has a well-earned reputation for leaking, because of poor design choices. There was the XG7 waterblock scandal a couple of years back and the H100i seemed to have a disproportionate number of leak complaints on forums.

Maybe they've learned their lesson, but IMO none of these leaky products should ever have made it to market. The design was questionable, the testing was clearly deficient.

I.. err..

With rising efficiencies PSUs should be increasingly passive, not active. I don't want to water cool anything. I don't want to water cool a CPU, or GPU, those are solutions to problems. This is a solution looking for a problem.
