Koolance offered the world's first water cooled ATX power supply in 2001. Now continuing with their patented line of innovative liquid-submerged power supplies comes the 1300/1700W PSU-1300ATX-12N. Completely flooded in a special non-conductive cooling liquid, the fan-less PSU-1300ATX-12N is superior to even "partly" liquid cooled and heat pipe power supplies.
Main Features
- Power efficiency is rated at 83% (avg) to 85% (max) for 110V, and 86% (avg) to 87% (max) for 220V!
- Four 8-pin and four 6-pin PCI-Express connections for convenient quad SLI and CrossFire™ support
- Two 8-pin 12V connections for server motherboards
- Internal temperature sensor allows monitoring when used with compatible Koolance systems (PC3-700/Exos-2 series and later).
Wattage - 1300 or 1700W Continuous!
Due to U.S. regulation, power draw over a typical household 110-volt AC line limits the PSU-1300ATX-12N to 1300W. However, the unit is fully capable of a continuous 1700 watts when powered from a 220V AC circuit. Users are responsible for supplying adequate AC power for the PSU-1300ATX-12N.
Heat Transfer Method
Featuring a compact liquid-to-liquid heat exchanger developed exclusively by Koolance, the PSU-1300ATX-12N provides the most efficient heat transfer available among any ATX power supply. Heat from each component is dumped directly into an internally circulating non-conductive liquid, through the heat exchanger, and out to an existing water cooling system. Thus, liquids are kept completely separate and normal cooling fluid can be used with the PSU-1300ATX-12N.
The PSU-1300ATX-12N is not a self-dissipating product and must be connected to an existing water cooling system via its external nozzle sockets (G 1/4 threading). A PCI L-bracket "slot adapter" is provided for easy hose routing back into the chassis through an available card slot. This helps reduce the power supply's internal length.
The PSU-1300ATX-12N is capable of producing some extreme wattages. When used at maximum output capacity, Koolance recommends a water cooling system capable of dissipating at least 250W of heat while powered by 110VAC, or 300W for 220VAC. This is in addition to other water-cooled components. In other words, if your cooling system is designed around a 700W hardware heat load (CPU and dual video card water blocks, for example), the PSU-1300ATX-12N should be allotted an additional 250-300W of cooling capacity. If unavailable, it is also possible to dedicate a separate cooling system solely for the power supply, such as Koolance's ICM-509 or Exos-LT.
Other Notes
- The PSU-1300ATX-12N can be used in most ATX, E-ATX, and BTX chassis that provide for 9.45" (24cm) power supply depths, not including cable space.
- The PSU-1300ATX-12N's small external liquid-to-liquid heat exchanger may conflict with some chassis that use restrictive rear mounting plates for the power supply. In most situations, minor modification to this plate (or removal, where possible) will fix the issue. [...to be detailed later]
- Due to the weight of the unit, an additional support bracket is provided for top-mounted-PSU chassis that might benefit from increased stabilization. [...to be detailed later]
- The only material in contact with the external cooling liquid is stainless steel.
