Koolance has been in the business of making water cooling gear for CPUs and video cards for a long time now. Way back in the day they even offered a liquid cooled PSU, which they have updated again, and boy is it sweet.

The Koolance PSU-1200ATX-12S puts out 96A over four 12V rails and uses modular cables, and offers four PCI-E connectors for the latest NVIDIA SLI setups or ATI Crossfire.

Koolance doesn’t merely put a couple water blocks inside the PSU and call this beast water cooled, they actually fill the entire enclosure with a non-conductive fluid that is cooled via an external radiator. Yes, the entire internals of the PSU operates in a submerged state.

The liquid cooling allows the Koolance PSU to put out 1200W of continuous power and a 1400W peak power output. Included with the PSU is a temp sensor that allows internal monitoring when used with compatible Koolance systems. The PSU is sized to be able to fit into most PC cases of ATX, E-ATX and BTX configurations that provide nine inch PSU depths including cable space. Pricing is $499 and the PSU is avaialble now.
