Introduction

We would like to thank Corsair for supplying the TX750M review sample.

The Corsair TX V2 series PSUs are solid performers with great price/performance ratio. However nowadays the demand for units with modular cables is increasing, even in the middle priced segment, so Corsair came up with the TX M Series. These PSUs use a different platform than the TX V2, and on top of that feature a modular cabling system which offers installation flexibility and makes cable management much easier, something that many users will greatly appreciate. Besides the platform change and the addition of the modular cabling system the visual appearance also changed since the TX M units feature the same fan grill design that we first saw on the HX1050W, where the fan grill covers only the fan's area and the case features some bumps that follow the lines of the fan grills.

The Corsair TX M series consists of four members with capacities ranging from 550W to 850W. In this review we will thoroughly test the Corsair TX750M. Summarizing, this is a single +12V rail PSU, with a 140 mm double ball-bearing fan which is temperature controlled, efficiency is 80 PLUS Bronze certified and the PSU is backed up by five years warranty. With a price difference of only $10-$15 compared to the TX 750 V2 the TX750M surely has a very competitive price.

Specifications

Corsair states that the unit does not have Over Power Protection (OPP). That's strange but since it is single rail, the OCP takes the role of OPP here (usually the opposite happens in single rail PSUs). The warranty is long enough so you will have your piece of mind and the dual ball bearing fan promises quiet operation. Finally at $120 we think it is well priced, since its price difference from the non modular TX750 V2 is small.


Not much to comment here. There is one +12V rail that can deliver almost the full power of the PSU and the minor rails (5V & 3.3V) are strong enough since they can give up to 150W of power. Also 5VSB has satisfying power capacity.

Cables & Connectors, Power Distribution

Cable length is sufficient and the distance among the connectors is very close to what the ATX spec recommends (150 mm). All connectors, except the floppy cable, use 18 AWG wires, the recommended by ATX wire gauge. Also as it seems Corsair forgot to include the Peripheral connectors modular cable with our sample since the official description refers to eight Peripheral connectors but we found only four, so one modular socket is left empty (the other is occupied by the SATA modular cable).
Sleeving on all cables is of decent quality and the unit features flat modular SATA cables for easier cable management. Speaking of the latter we would like to see more modular cables and less native ones. Finally we should note here that if you choose to connect the second modular EPS cable then you have to sacrifice a modular PCIe connector.

Since this PSU features a single +12V rail we do not have anything to comment about its power distribution.

Packaging

The front of the box is covered by a close up shot of the new fan grill design that the TX M series PSUs utilize. We saw it for the first time in the Corsair HX1050W and we liked it very much. For now it seems that Corsair will use this design on all of their new PSUs. As expected, on the rear side of the box we find much more useful information regarding the cables/connectors of the unit, efficiency and noise curves, power specifications etc. On the bottom and top sides we find less useful information so you can safely skip them.
