Corsair RM750x review

Corsair already have a wide range of power supplies available for the enthusiast audience as you can see if you look at this listing page on Overclockers UK. Their updated RMi series was launched in June this year with Corsair Link Support. The RMx units are supplementary to the RMi series – both have 80 Plus Gold Certification and are modular, however the RMx series do not have Corsair Link Support which will enable the company to hit slightly more competitive price points.

The RMx has been updated to incorporate 100% Japanese capacitors in both primary and secondary stages. The RM series only had Japanese capacitors in the Primary stage. The RMi series has a 140mm fluid dynamic bearing fan which in our tests proved to be a little quieter than the Rifle bearing featured in both RM and RMx units. To be fair, both units are relatively quiet and seem built to last. Corsair seem confident in the design and have increased the warranty from the RM series 5 years coverage to a full 7 years.

Technically, the RM750x is a solid CWT design which doesn’t compromise on components or build quality. Load regulation is stellar and the power supply achieves the 80 Plus Gold standard without a problem. CWT do deserve acclaim for these recent designs alongside Corsair.

The new ‘Type 4’ flat cables will appeal to the demanding enthusiast audience. The 8 pin cables for the ATX 12V/EPS12V and PCIe are pin compatible with Type 3 cables but they incorporate capacitors to help reduce ripple noise. This is actually one of the big selling points for the RM750x – the class leading ripple suppression which is as good as we have seen.

Lastly, the external finish meets the standards we would expect from Corsair and the fully modular design will appeal to enthusiast users who want to showcase an attractive, tidy build behind a windowed panel.
