Koolance 1200W Liquid-Cooled Power Supply
Koolance 1200W Liquid-Cooled Power Supply

In 2001, Koolance offered the world's first water cooled ATX power supply (230W). Koolance now sets a new record with the first 1200 watt liquid-cooled power supply!

The patented Koolance PSU-1200ATX-12S features 96A (simultaneous 12V@85A) over four 12V rails, and 4 PCI-Express connectors for SLI™ and CrossFire support. It is able to unleash 1200W of continuous (1400W peak) power at greater than 80% efficiency by operating in a completely submerged state. This patent-pending design is superior to even "partly" water cooled and heatpipe power supplies. All internal electronics are immersed in a non-conductive fluid and dissipated through an external heat exchanger.

Being self-cooled, Koolance's 1200W PSU requires no connections to any other type of water cooling system. The unit comes pre-filled and no ongoing coolant maintenance is required. The quiet 120mm LED fan is temperature-controlled and operates between 25-33dBA. An included temperature sensor allows internal monitoring when used with compatible Koolance systems (TMS, RP-1000, PC3-700, Exos-2, and PC4-1000 series).

The PSU-1200ATX-12S can be used in most ATX, E-ATX, and BTX chassis that provide for 9" (23cm) power supply depths, including cable space. The external heat exchanger is highly adjustable to maximize chassis compatibility. Being slightly wider than the internal power supply, it can be rotated 180° and moved vertically 2" (5cm) to help avoid physical conflicts. Quick disconnect shutoff valves allow for the convenient attachment of the heat exchanger during installation.

NOTE: The PSU-1200ATX-12S will operate in two mounted directions (standard/upright and on its side). Please see the user manual for details.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
