What do you think the limit of a PCB or the entire GPU is. i have a GTX 460 and according  to bit-tech.com is comumes 135-140 watts at idle and 250-270 under load. I want to overclock my GPU when I get a new PSU because mine currently can't handle it and I was wondering how much juice I could pull through the PCB before it blows up. I have in the past hot 890Mhz on my GPU and it was stable but I started to smell burning form my GPU...

I'm not entirely sure, tracers are rather small, but even then I'd be thing somewhere up in the 10,000 watt region, even that won't guarantee an explosion

I am good at computer
