Hi, I'm trying to repair my xbox v1.6 with a Delta 220v PSU because it doesn't power on at all(even the fan isn't spinning). Backstory: the xbox stopped working all of a sudden(it worked just the day before even with the leaked/bulging caps), so thinking that maybe the power and eject buttons got broken, I tried to turn it on by shorting the SW1 Eject or SW2 Power(I can't remember which) to GND according to this diagram of the front panel connector. I don't think this was a good idea since the xbox didn't turn on and I heard a small spark but I'm not totally sure. Now from the PSU, not plugged into the motherboard(so in stand-by I guess), I get a ~5v reading from the orange wires but 0.1v from the blue wire(which should be 3.3v even on stand-by according to this table) and ~0 volts from the other 3.3v and 12v rail as it should be. Moving on to the motherboard, after removing all the bad capacitors, I still get a short between the 5v rail and ground(measuring the pins of psu connector on the motherboard). I also tried measuring the caps under the CPU(starting from C2P1 to C2P17) and they're all shorted to ground. The caps C2E2 and C1E1 too. Also, measuring the VRM(?) FAN5059M I'm getting a short on the pins(apart from GND) 2_SW, 6_VID2, 8_VID0, 20_VFP. All this leds me to believe that the CPU is fried but I can't really wrap my head around how I could have done that, is there something I'm missing/misunderstanding?

Long story short While modifying my Xbox, I accidentally shorted out the 5 volt rail. Now the thing doesn't turn on. I'm wondering what exactly I killed on the power supply. I checked the fuse near the 120Vinput and it appears to have continuity. I notice basically right next to the wires for 5v there appears to be a regulator or a mosfet. Perhaps it just needs a new mosfet? The short only occurred for less than a second. Personally I find it kindof rediculous how it killed it so quickly but nonetheless. Needs fixing now. Also on another note. I know this is a long shot, but could the power supply from an Xbox Revision 1.0 be rigged into a newer box. I see that the connector for the old Xbox is only 12 pin and the newer one is a 20 pin ATX. What crossed their minds to change over to the ATX power supply?
