Load testing - stability Testing the PSU

So let's zoom in at load testing. When we focus solely on gaming load for a second we see that the PSU draws 479W from the wall socket which seems to to smack down in the middle of where a Silver certified PSU should be. It's roughly 15 Watts away from Platinum certification actually.

Stability Testing the PSU

So during our tests we also monitor the voltage fluctuations as shown below in both IDLE and LOAD states of the PC. We write down the lowest and highest value we see within a certain PC state. The difference is the fluctuation. If a PSU is unstable we'd see a lot of fluctuation, differences and discrepancies which can result in system instability.

Once we gathered all Voltage results we can place them in an easy to understand chart. Look at the chart, the two lines show both the Idle and Load state of a specific voltage rail, the dark blue one the lowest voltage dip measured, the red one the highest fluctuation. That's your baseline.

So then, ATX specification requires that the PSU needs to stay within a 5% fluctuation; for example, each +12 Volt rail should remain between 11.4 - 12.6 Volts.

As you can see, the PSU when utilized stays consistent as you can hardly even see the blue line, meaning that the PSU is functioning within ATX specified limits. During the load test, I checked several times to see if the PSU was warm, it was cold to lukewarm really.
