Well, things don't always go to plan.

Today was supposed to be a video of this 400W PSU under load and a comparison of it with a Sunon fan also under full load.
Both PSU's performed as expected with the Sunon fan swapped unit being much quieter than stock, but our recording equipment didn't like what it was watching so much.....

This PSU will never be silent like the 600W with a Noctua fan, on account of its lower efficiency but more so more agressive fan voltage map that ramps up to full voltage/speed at full load with high thermals. That said the acoustic noise signature of the Sunon fan is cleaner and quieter than the ADDA. Not as clean as a Noctua fans sound signature on like for like cfm, but for this PSU that is simply not an option.

So for now just a quick intro / overview on this PSU.
