Thortech Thunderbolt 1000W Modular 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.

As expected, the ripple on this unit does not really compete with the more established companies on the market, but is certainly not bad either. Again, this fits perfectly into the gaming market for those who want a powerful PSU that juts ‘works’ rather than providing enthusiast-level performance that would not be beneficial for the gamer and would be unnecessarily expensive for his needs.
