Default Xbox Power

My friend's old xbox stopped working after a power surge, and he gave it to me.

I took an old computer powerbox, and attempted to hook it up to the xbox, since they have almost the same power specs. The motherboard plug was different, so i cut the wires which colors' matched that of the 12 wires going to the xbox motherboard. After hooking them up, I got the fan on the xbox to twitch! lol. After cleaning the dust out of the powerbox, i noticed that both fans on the powerbox and the xbox twitch in unison, so Im guessing theres some problem i need to resolve with the powerbox. Could it be a circulation/security issue, so the powerbox cuts the power because it senses too much power coming back? please help.

I know xbox power supplies are only 20 bucks, but wheres the fun in that?

ATX93-3405 is the model of the powerbox. ASTEC

I would find an Xbox on Craigslist or Ebay with a broken CD drive or something and just replace the PSU with that one.

You can just buy an Xbox PSU on eBay for about $20, so it wouldn't be worth buying a whole new Xbox xD.

well you can use a v1.1 psu with a 1.3, so if you can find some info on a 1.1 here is a link:

Xbox-Scene Tutorial: Use v1.0/v1.1 PSU for v1.2/1.3 console

here is another link

Xbox Power Supply Adapter - ATX to XBOX

it seems like the xbox is shutting down because of over current. the 5vsb rail is downconverted to 3.3v, so pretty much, an xbox has a 3.3Vsb.

and one last thing, what version is the xbox? like 1.3, 1.4, 1.5, or 1.6?
