Questions about computer PSU

I've recently been looking around for a 12V power supply that outputs 40-50 amps. Seeing that commercially made SPSs are not cheap, I've settled on using a computer PSU(Probably in the 650-700W range). I've noticed that most of the computer PSUs have 2-3 12v rails; unfortunatly the individual rails don't provide enough current. Would it be possible to parallel them together to get the full 40-50 some amps I need?

Another concern I have is the gauge of the PSU wires; I'm pretty sure they're not rated for 40A. Are the wires isolated from each other or are they in parallel to their respective supply rails?

Any info would be appreciated

I don't really know much about the internals of the PSU although I have always been told to not mess with them internally for various reasons. You can however obtain a PSU with the 12v on one rail. I usually recommend PC Power and Cooling however they are out of stock on Newegg as of today. OCZ did buy out them though and I found this one easily enough.

Newegg.com - OCZ Fatal1ty OCZ700FTY 700W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Power Supplies

I have also used Thermaltake brand power supplies before but of the top of my head I don't know if it was a single rail or not.
