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.
The 12V and 5V rails have a really tight <1% regulation, while the 3.3V rail holds very steady at a respectable 1.3%.
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 160mV peak to peak ripple, Pretty good overall which is great considering this is the primary rail.
The 5-volt rail comes in around 240mV of ripple, not bad, but not setting any records.
The 3.3V rail does a decent job with 160mV of ripple, again solid, but not mind-blowing.
