Thortech Thunderbolt Plus 800W Power Supply Unit 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.

We can see that the ripple results are a similar story to that of the standard Thunderbolt units- a good, solid performance, but not something that will be challenging the likes of Enermax. I think this is good as on the PSU market today there is a clear distinction between cheap and nasty- will blow up your computer type units and high end units from Antec, Corsair and Enermax but there is very few that bridge the gap, providing a compromise of quality and value.
