The 80 PLUS Bronze-certified Xigmatek NRP-PC402 makes a good impression right from the unpacking. Xigmatek includes a power cord, screws, and power ties in a single separate box, and the build quality is solid. Cables are sufficiently long and well-wrapped in sleeves.
In addition to the box you see above (pro tip: periodically blow out your PSU to prevent foliage from growing in the accumulated dirt), the PSU also comes packaged in a cheap little bag. Xigmatek did not skimp on the overall package, though. The NRP-PC402 comes with four Molex connectors, eight SATA connectors, and a 6-pin PCIe connector.

Looking at the picture and the fan alignment it seems otherwise.
While your tests show that these PSU's perform up to or even above their power output specs, that's not the whole story. You say you have an oscilloscope, but where are it's readings across all those load tests? What about voltage fluctuation measurements across them as well?
I just think you're capable of providing more thorough tests and results.
Oh, and it was interesting to see a real PSU blow up

great video, Ive always wanted to see a PSU explode lol.

The initial request makes me think these were cherry-picked, rather than selected from a Retail source. That bodes particularly poorly for AXP; looks like they should not be legal for sale.
If you doubt this, try using a kill-a-watt meter or equivalent. Most mainstream PC's idle lower than 100, and max lower than 250.
