Corsair TX750M 750W Modular Power Supply Review
Jake Sedge / 13 years ago
In this test we subject the unit to various loads and measure how it effects the rail stability. In theory, a power supplies output waveform should be flat, but this is never the case. What you see is a very zoomed in view that tells us how stable the rails are by looking at how much ‘ripple’ there is. For more information, please take a look at our PSU Testing Methodology article where you can also see an example of what a poor quality unit looks like on our oscilloscope.

The ripple on this unit is extremely low, for whatever reason I was expecting it to be higher, but Corsair once again have clearly delivered a product that can only be touched in terms of performance and quality by the top brands. These ripple results are a real demonstration of Corsair’s design approach and quality-first ethic which keeps them as one of the best regarded PSU manufacturers around.
