Final Thoughts and Conclusions

Corsair continues to offer a very complete selection of PC power supplies and the new TX Series fits squarely in the middle of their product lineup. The TX750M delivered excellent voltage regulation across the board during our tests. AC ripple and noise suppression was good with all values staying well below even half the recommended ATX guidelines. And the power supply easily met the criteria for 80 Plus Gold efficiency certification while operating on 120 VAC and at elevated temperatures. And the TX Series PSU chassis measures only 140mm (5.5”) deep.

The TX750M is semi-modular which means the main 24-pin ATX cable/connector and 4+4 pin ATX12V/EPS cable/connector are fixed while all the rest are modular. The build quality is very good and Japanese made capacitors are used throughout. The power supply is quiet over most of the output range and only became noticeably noisy at full load. And last but not least, Corsair is backing the TX750M with a 7-year warranty. It’s hard to find anything not to like about the TX750M but while the 120mm riffled sleeve bearing fan is probably a good choice for this PSU we would prefer to see a more robust Fluid Dynamic Bearing fan used.

The MSRP for the Corsair TX750M power supply is $99.99 USD (, May 2017).
