Specifications

The ETA-A and 80 PLUS Gold ratings are common for PSUs with 750 W max power in this price range, but some have much better noise ratings than LAMBDA-S++. Take, for example, the RM750x (both the old and new version) with an LAMBDA-A (15-20 db[A] overall noise output) rating. The Bitfenix BWG750M also manages less than 30 dB(A) overall noise output for a LAMBDA-A- rating.

According to Cougar, all protection features are present, while the maximum operating temperature for a continuous full load operation is 50°C. The PSU's cooling is taken care of by a 135 mm fan equipped with a hydro dynamic bearing, which is just another name for the fluid dynamic bearing and allows companies to avoid paying the patent fees that come with the FDB naming scheme. There is no semi-passive operation, which could help keep noise output low under light and moderate loads, while the PSU's dimensions are pretty compact with 15 cm of depth. Finally, the provided warranty is long at seven years, and the MSRP for the US market, once the PSU becomes available there, will be around $100.


The maximum combined power the minor rails can deliver is too high for a modern system's needs. Typically, the +12V rail can deliver almost the unit's full power alone, while the 5VSB rail can output up to three amps.

Cables and Connectors, Power Distribution

Four PCIe connectors are enough for a 750 W PSU, but one EPS connector definitely is not. Cougar should equip this PSU with a second EPS connector in order to make it compatible with mainboards requiring more energy for the CPU socket's area. More clearance between the peripheral connectors would also be nice.


Here are some photos of the unit's cables.

Since this PSU features a single +12V rail, we do not have anything to comment on when it comes to its power distribution.
