The name of the FSP Saga II 400 is a bit grander than the PSU itself, which is of slightly lower quality compared to the other test candidates. At the same time, it's also the most affordable unit in this roundup. This model is one of two devices with no support for 115 V, making it a fancy-looking brick here in the US. You'll only be able to use this one if you're in a country with 230 V power.
At first glance, the 400 W PSU looks like a relic from the past, even if the matte white paint provides a welcome change.
Despite its affordability, FSP's bundle is on par with the other PSUs. The box includes screws, a power cord, and an FSP sticker. Unfortunately, most cables are just under 12 inches long and, aside from the normal ATX, CPU, floppy, and 6-pin PCIe cabling, the Saga II 400 only offers three SATA and Molex connectors. Thus, it might not be suitable for larger enclosures optimized for good air flow. Rather, the Saga II probably belongs in compact systems.

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.
