So i bought an old-stock Apevia X-Qpack. This comes by default with a "420W" power supply. Since i read this review from JonnyGuru, i thought it would be crap:

But i think i've got a newer revision of this psu. Mine got a passive PFC and looks rather complete. I've added some pictures to show it to you guys.
The primary:
- a pretty much complete input filtering stage
- Real 250W Passive PFC coil with an added capacitor
- 2x 2SC2625
- KBL406 bridge rectifier
- 2x 470uF primary caps
The secondary:
12V: SFR20100 Schottky 20A rectifier, pi coil
5V: SBL3040 Schottky 30A rectifier, pi coil
3.3V: SFR20100 Schottky 20A rectifier, pi coil
The secondary caps are really crammed together so i still have to take a good look at them to know which one is for which rail. All caps are Fuhhyu ones. The PCB says this is a YoungYear unit. It also is 230V AC only and it seems that if even has a temperature controlled fan.
Now, when i look at the power supply and the components it uses, i really think that the unit JonnyGuru reviewed maybe had a 10A rectifier for the 12V rail?
If i recap the secondary output stage, will i have a reasonable 250W PSU that can deliver about 200W on the 12V rail?
