I didn't make the connection (no pun!) until now, but I've got a PSU for sale that might suit you.
Its this one here: http://www.scan.co.uk/products/520w-ante...e+shopping
It's got a single 12v rail rated at 40A though technically it should be able to deliver more for short periods of time. Its brand new and I'm looking for about £30 if you think it'd suit.

You know what you're doing in terms of wiring it up? Like, yellow is 12v, red is 5v, blacks are all ground (but may be separate depending on the rail configuration) green is the wire to ground to turn PSU on etc. etc.
I imagine to pull more than 10A through it you'll need to use multiple yellow wires as although the PSU is rated highly the wire is only good for a few amps. You might need to open up the PSU to identify which wires are which rails if it has multiple 12v rails (which by the sound of it it doesn't).
