Corsair TX750W Review - Updated

Price: $109.99


If right now you are thinking OCC has already reviewed the Corsair TX750W, then you would be correct. It was last looked at here in June 2008, so please go back and have a look at ccokeman's review and see how OCC once tested power supplies. Installing a power supply in a high end PC, software stressing the processor and graphics card to load the power supply and measuring the rail voltages is one way of testing. Some people might say this is a "real world" way of testing power supplies and many review sites are still doing it this way but, and I'm sure OCC won't mind me saying this, it can be done better.

Corsair has kindly supplied another TX750W power supply to OCC and this time round I will be loading the power supply up to or very near its maximum power and seeing how it performs. My testing methodology is by no means perfect, but it is the next logical step up and I'm confident my test regime will give accurate results from which I can reach a fair, accurate and valid conclusion.

"Enthuiasts looking for the optimal in price performance PSU technology will find the Corsair TX650/750W series of PSUs will meet even the most demanding of required specifications. The Corsair TX650/750W power supplies are engineered using advanced technology and components typically found with high performance power supplies. With design features such as a dedicated, single 12V rail, the TX series offers the maximum compatibility with the latest system components. Energy efficient circuitry capable of delivering 80% efficiency ratings across 20%, 50% and 100% load conditions make the TX family of PSUs ideal for the value/quality conscious enthusiasts. With a large 140mm (120mm on the TX650W) diameter temperature controlled fan that is ultra quiet, yet still more than sufficient to cool the internals of the system, reliability and stability are no longer worries for the gamer, overclocker or enthusiast and high end system builder. Each Corsair TX power supply is backed with an industry leading 5 year warranty and 24/7 on demand customer service."

Let's have a look at the Corsair TX750W and see how it performs.

Closer Look:

The Corsair TX750W packaging once again closely follows the layout used for the rest of its power supply range. This time around a black and orange theme is used. The lid shows the usual arty photograph of the power supply, a short five point list of the main features of the power supply in English, Spanish and French, the Corsair sailing ship logo with large TX750W logo and finally a five year warranty, 80 Plus and SLI ready icon. The underside of the box contains a wealth of information with various close up photographs of the power supply, a core features list, specification table, part number CMPSU-750TX and audible noise and efficiency graphs.






On the sides of the Corsair TX750W box there are photographs and quantities of all the connectors available along with a short paragraph or two, in three different languages, introducing the power supply and its main features



The sides of the box are identical and show the Corsair logo along with model number.



Lift the lid and the first thing you see is the user manual on top of the foam envelope that encases the power supply. The TX750W is non-modular and all the cables are neatly bound and tucked down the side of the power supply along with the power chord. The power supply is contained in a draw string black felt bag.

The Corsair TX750W is well protected against transit damage and includes all necessary accessories for a successful installation. Let's have a look inside the felt bag.
