360 Power supply Failed.... This may interest you...

So my power supply jacked up recently, started making this crazy grinding noise. for the first week, it would turn on and grind for a while. here is the kicker, i would literally pound the box, and it would stop and Just be silent for the rest of the time it was turned on... this worked for about a week.

Then it just started being noisy and grinding no matter how hard I pounded it.... and would still work but make the grinding noise still.... so then...

I thought.......well, the KINECT IS PROBABLY PUTTING MORE WORK LOAD ON MY POWER SUPPLY since I have the new slim model, it does not plug into the wall independent. it uses the same power supply as the 360.

So I unplugged it.......and my power supply works for the most part flawlessly, without any noise. NOW........This does not SOLVE any problems, for i have not tested plugging the kinect back in.... I dont care to use it anyway its pretty much an over priced microphone. and if I ever did want to use my kinect again, I would probably experience that same crazyily annoying grinding noise.

This is more of a work around / informative point than a total fix for a problem that seems to be aggro'ing a lot of us 360 users, and I am curious to see if it works for anyone else.

Cheers.......and Have Nice Day.

I don't see what the kinect has to do with anything. The noise can only be the fan going out. Very strange. All I can think is maybe the kinect puts a heavier load on the power supply, therebye making it work harder putting more of a load on the fan motor. In any case you may want to see if you can buy a replacement fan motor before it locks up and causes the unit to overheat and possibly damages or even destroys it.HilbillyRokstar

And that is exactly what I suspected, and i was seemingly right. NOW however, my xbox power brick is completely dead, or shuts off after 20 or so mins. but getting a new 1 tomorrow.
