I wouldn't think that Asus would piggy back such a task onto the processor like that...

And the fact that this component was the first thing to go in both our mobos in the case of a power spike makes me want to believe it was acting as a fuse of some sort to protect the board in this very situation...

it would be really nice if someone with a working Asus k50i v2.3 mobo could identify the part for us though.. I tried looking up a picture of the board online to see if I could make out the chip but...
