Up to 91% of efficiency, compliant with 80-PLUS® SILVER efficiency requirement . Due to the extremely high efficiency of the COUGAR® S-series you can reduce your electricity costs in spite of high performance.

COUGAR® SX provide highest efficiency performance and less wattage loss.

COUGAR® SX CLC filter design efficiently suppress Ripple/Noise <1%

Advanced HDB (HYDRO-Dynamic Bearing) fan provide best lifespan and super silent performance. Temperature-controlled design adapts its rotating speed to the PSU temperature. Even on its highest rotating level the fan is still quiet enough to be barely noticeable.

Better CFM means fan can provide better air flow and cooling performance.
14cm and 12cm fan can provide much better air flow just require lower rpm than 8cm fan, therefore, 140mm fan is much better cooling performance, but is extremely low noise and longer life of the fan.

DC-DC technology for switching PSU has smaller volume, the highest efficiency, the most stable performance and perfect regulation.(<3%)

COUGAR® use the highest durable 105°C Japanese capacitors provide uncompromised performance and reliability, delivering 4 times the lifespan of conventional 85°C rated capacitors.

The best solution for a High-End PSU by using solid caps for 12Vs, 3.3V, 5V, solid caps provide highest efficiency, best reliability, and extend power lifespan.

The modular cables that reduce air friction help maximize airflow through the PC case. The modular design also simplifies installation as it allows unprecedented flexibility in using only those cables which are needed.


Dimension (L*W*H) mm 180 x 150 x 86
UVP (Undervoltage protection)
If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off.
OVP (Overvoltage protection)
If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off.
SCP (Short-circuit protection)
In the case of a short-circuit this feature prevents damage to the core components of the PSU and its system components.
OPP (Overload protection)
If the system is oversized and requires more power from the PSU than it can perform, this protection function is activated.
OCP (Overcurrent protection)
If the load on a single line is higher than indicated, the PSU automatically switches off.
Power and silence in one bottle text: Alexey Ignatyev Power supply Cougar SX850 is delivered in a black-brown box and the aggressive logo on it reminding an emblem of a sports car. The steel case of a power supply has a pleasant rough covering and bright painting. The delivery complete set includes the instruction, several screws, a collar for cables and molex-FDD adapter. click here for the total Review
