This PSU has both the Cybenetics ETA-B and LAMBDA-A++ badges and is 80 PLUS Gold certified. The LAMBDA-A++ noise badge is representative of a very quiet operation wherein a unit's overall noise output stays below 20 dB(A). In an effort to restrict production costs, there are no modular cables; none of these can be removed.

The maximum operating temperature for a continuous full load is restricted to 40°C, and all the necessary protection features are present. This unit's cooling duties are handled by a 120 mm FDB fan that isn't supported by a semi-passive mode, but we don't mind the lack of a semi-passive operation as long as the fan's RPM is low at light and moderate loads. Finally, the warranty is long enough at five years, and the unit will set you back nearly $90. $90 is enough for a unit with modular cables and a similar capacity from other brands, which means the BF750G will have to do quite well in terms of performance to be competitive.

There are four +12V rails, of which two have 10A more current output than the others. The maximum combined power of the minor rails is enough for a modern system, and the 5VSB rail has the capacity typical of a contemporary PSU.

There are two EPS and four PCIe connectors, and eight SATA and four 4-pin Molex connectors. Given this is a non-modular unit, we are happy with the number of available cables and connectors, and the distance between connectors is 15 cm, which is perfect.
