Corsair TX750 V2 750W & TX850 V2 850W Power Supply Review

Price: $104.99 & $124.99


Founded as Corsair Microsystems in 1994, Corsair originally developed level 2 cache modules for OEMs. The release of Intel’s Pentium Pro processor with built in cache memory led Corsair to change their focus to DRAM modules. In 2002 Corsair began shipping memory modules specifically with the enthusiast in mind and today their high performance memory modules are probably the product that most enthusiasts associate with Corsair. Corsair has expanded its product range to now include power supplies, computer enclosures, processor coolers, solid state drives and other key system components.

The Corsair TX650, TX750 and TX850 power supplies have now been around for some time and I guess rather than discontinue what has proved to be a very successful product Corsair have decided to keep the model going a little longer and offer a few improvements with the V2 units. This time around OCC will take a look at two power supplies from the V2 range, the TX750V2 and TX850V2 power supplies and see just what improvements, if any, Corsair have made.

Closer Look:

The Corsair TX750V2 and TX850V2 boxes, with their yellow, black and white theme, are basically the same apart from model numbers and technical specification. The top face of the box shows a photograph of the cooling fan side of the power supply along with model number, Corsair logo and a small box in the top right hand corner showing it’s a V2 unit.













The bottom face of the box carries all the technical information including connector types and quantities (with photographs), the main features in five different languages, fan noise and efficiency graphs and specification tables.



The front face of the box shows the model number and V2, a further list of features in five different languages with a five year and 80 Plus Bronze logo.



Model number and V2, a photograph of the fan grill, more features, again in five different languages and conformance marks on the rear face.



The box comes with identical end panels that carry the same photograph as the rear face with the model number and V2 once again displayed.



Both power supplies are contained in a further brown cardboard box bearing the Corsair logo.


Lift the lid and both power supplies are identically packed. The instruction manual which covers the TX650, TX750 and TX850 sits on top of the foam protected power supply. Removal of the top foam cover reveals a black drawstring bag enclosed power supply with the cables, power cord and accessories neatly stored down the side.



The black drawstring bag with Corsair logo along with the full box contents which includes the power cord, user manual, cable ties, case badge and power supply mounting screws.


The Corsair TX750V2 and TX850V2 power supplies are well packaged with a good set of accessories so let’s move on and have a closer look.
