Corsair HX750W is an impressive power supply, being to this date one of the power supplies with the highest efficiency that we’ve tested to date, easily beating all other 750 W power supplies we’ve tested, including those also based on a DC-DC design on the secondary like Antec TruePower New.

Not only the DC-DC design proved to be superior, but Corsair/CWT decided to use only high-end components inside this unit, which features only Japanese capacitors and solid caps on the DC-DC converters in charge of the + 5 V and +3.3 V outputs.

We could also pull up to 910 W at 46º C from this unit, which is really impressive.

The number of cables available is perfect for a 750 W product (12 SATA power connectors, eight peripheral power connectors and four six/eight-pin video card power connectors), allowing you to build a very high-end system with two very high-end video cards (more video cards are supported if you use adapters to convert standard peripheral power plugs into video card power connectors).

The seven-year warranty – losing only to BFG’s lifetime warranty – is also another reason to pick this product over competitors.

Corsair HX750W is a very good choice for users looking for a 750 W power supply with one of the highest efficiencies around.
