GPU: Nvidia RTX 2080 Ti Founders Edition

SSD: OCZ RD400 512GB

OS: Windows 10 Professional X64

We’ll start out saying we aren’t equipped to do extremely detailed electrical analysis required to pick apart a modern power supply. It takes laboratory grade dedicated equipment so we’ll have to make do with some less precise testing.

While we normally use a good Fluke Digital Multi-meter, we’ve found the onboard monitoring solutions in modern motherboards to be quite accurate and able to be easily logged with utilities like HWiNFO.

Next, we’ll look at ripple on the rails with our Owon VDS-1022/I Digital USB Oscilloscope.

 The +12V rail under a stress test load registers a peak of 120mV peak to peak ripple.

 The 5-volt rails fairs about the same at around 120mV of ripple peak but also averages much lower.

The 3.3V rail does a decent job with 160mV of ripple. Modern systems typically put very little load on the 3.3V rail.
