A Detailed Look – The PSU

When I first heard that Koolance was about to release a liquid cooled power supply, I assumed that it would incorporate one or more waterblocks instead of the heatsinks used in traditional air cooled PSUs.  However, I soon learned that the new Koolance 1,200W power supply uses true submersive cooling.  While some hard-core enthusiasts have been experimenting with various forms of submersive cooling for years, this is the first commercial PC product I am aware of that uses this technology – wow, now that’s kool!

The Koolance 1,200W liquid cooled power supply is big and heavy.  The build quality appears to be very good and the fit-n-finish is excellent.  A combination of tough engineering plastic, black anodized aluminum and steel parts are used in the construction.  The Koolance name is laser-etched into the sides and top.  Add in the blue LED lighting effects and this power supply is a real looker.

Attached to the front of the power supply is a removable radiator and fan assembly, which is hinged and swings out to provide access to the rear panel connections and hoses.

When the power supply is mounted into a PC enclosure the back panel is flush with the back of the case, leaving the radiator/fan assembly sticking out the back of the case for good air circulation.  The back panel has connections for a power cord, radiator fan cable, and two coolant hoses.

The Koolance 1,200W liquid cooled power supply is rated for a combined, continuous output power of 1,200 watts at up to 40°C ambient air temperature (1,400W peak).  The Koolance PSU incorporates universal input (automatically adjusts the AC line voltage) and active PFC that adds to the units environmental friendliness.

Notice that the majority of the rated output capacity is supplied by the +12V section.

This is typical of most newer power supplies and a result of changes in the PC industry that more and more rely on +12V instead of +5V and +3.3V.  With over 1,000W of power available on the +12V rail, the Koolance PSU should be capable of powering most any new system you may want to build.

 

Quad +12V output

 

The Koolance 1,200W PSU incorporates four +12V outputs.  As is the case in most PC power supplies, the four +12V outputs are all derived from a common +12V source and differentiated with individual current limiting circuits.  The following table shows the maximum rated current and what connectors are supplied by each output.

Note: The maximum combined load for all four +12V outputs is 85A (1,020W).
