Modular. 12v+ 4 rails @56A (if focused)
First make 100% sure the modular feed is connected properly (if you have messed with the cabling a lot over the year, it is very possible the modular power connector is no longer making proper connection 100% of the time). This is the biggest problem with modular power supplies.
On your powersupply, each rail can only get a maximum of 20A. This is why I said focused above (adding them together) remember tho, 4x20A DNE 80 AMPs. I will assume you are using 1 rail for the CPU, 1 for harddrives/cdrom, and one for the video card?
Ill add this: When using multiple rails, the maximum value is ONLY ever obtained if that is the only rail being used. 1 rail = 20A max. 2 rail = 28A max. 3....4 = 56A. Undernearth where it shows 20A value for each rail on your PSU it shows 56A max (this means 14A MAX per rail if all 4 are being used). You are probably underpowering the card on the 12V line (pulling to much power could have been why your powersupply "Shorted" if it does have a blown cap)
Edit 2: Most 470s I can find require 220W (18.33333Ax12v) which is more than your supply can handle per rail unless they are focused.

Ok, interesting. So my PSU virtually took a dump them due to over stressing the rails. Makes sense.
A guy on Bit-tech is thinking its the mobo because the GPU sits on top of the southbridge meaning the south bridge could have went. I find this also a plausible theory. What do you think?

Its always possible, but highly unlikely. Id just replace the PSU (you will have to either way for the GTX470, and try to find one with a single rail @60A or so) and try it that way. Was the card physically touching the SBCS, or just its passive heatshink? If I was a betting man, my money would be squarely on the PSU. Tho it is very possible you shorted the board trying to get that monstrosity known as a GTX 470 in the machine (bent it a bit much if the mounting screws are to tight, etc).

Ok, seems you are probably right. I just cross jumped my PC with my friend's PSU's rails. Instant boot on my system. The PSU is the cause it would seem. Looks like im getting the ABS Majasty 1100w PSU. Its modular but rated at 83a on all 12v rails. lol

If im reading this right, there is one single rail @ 83A. Absolutely PERFECT and will do everything you want it too. Single rails are almost always > multiple rails for comps now a days anyway. Before the new ATX spec, to be "certified" a single rail COULD NOT supply more than 240W (12v @20A like your current PS). This caused big problems, so they split the rails to adhere to this policy (problem is, the source is still the same, why you could not split it properly...IE no 20A per 4 rails = 80A).
Enjoy your PS, getting it from Newegg I think? Let me know how it all works out for ya :)
