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?
Has any one really had a look for the differences between the 110 and 220 volt supplies. I have started comparing a Jap PSU (100-127 volt) to a Aus PSU (220-240 volt) and so far the two main differences is the Aus spec has a extra power filter on the AC input and the Jap version has a hidden link under the main power filter The part with the red star is on the 220 volt and on the 110 volt there is a link at the red arrow The blue arrows are the only difference I have seen so far as far as the different input voltage and the link is doing the same as a universal Xbox PSU I have that has a 110/220 switch. It is looking like you could add a link to make a 220v into a 110v or remove it to make a 110v into a 220v version. https://imgur.com/a/g5nWjqw Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.
