NZXT HALE90 750W 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.

The ripple on this unit is quite simply excellent! This really shows the unit in all it’s high-quality glory and demonstrates the excellent performance that the NZXT has achieved with their very first power supply- outstanding. Admittedly, ripple this low is not new, but on a power supply of this value it is fantastic to see!
