For our tests we used a modern based PC system, based upon AMD Ryzen 5. Testing PSU is not something easy, we used the user side, meaning we gave to our system enough load either through extensive CPU+3D usage via 3D Mark Vantage and PC Mark Vantage. The following table lists the industry wide specifications for DC Output Voltage Regulation.

After running both benchmarks, the monitored outputs showed us how much stress the PSU has taken. A summary of the results can be found at the following table:

		Minimum	Maximum
+3.3 V	V	3,29	3,35
+5 V	V	4,97	5,12
+12 V	V	11,94	12,12

The results are good since are within the standard range and we didn't notice any issue with our long period of testing.
