Pleas do note that the 1,200w applies to TOTAL output of all rails including the 5v and 3.3v ones. The 12v rail is rated for 84A = 1kw.

Go on ebay and buy if you can find the butteryfly labs PSU that were meant to mine 24/7 they are beefy.

I got one for my home computer.

   Many PSUs that have "multiple 12v rails" in fact only have one supply circuit, with multiple over-current/short-circuit protection channels.  To find out what your PSUs has, connect an ohm-meter between the two 12v rails that you want to connect together (with the PSU off, of course).  If it reads a low resistance (like <2 ohms), they are connected together inside the PSU, and the PSU shouldn't know any different if you connect them together externally.

    Now let me explain why PSUs have multiple 12v rails.  As CPUs and GPUs have become more hungry for 12v power, the amperage that PSUs must be able to supply has increased.  The problem is that the individual 12v output wires aren't very thick, and now, a PSU capable of 50A on the 12v rail could present a fire hazard if one of the cables got shorted (or overloaded), since a single wire may not be strong enough to trip the PSU, and will certainly overload long before the PSU does.  So the multiple "rails" on many cheaper PSUs are really there only for safety, rather than anything to do with isolation or providing extra power.
    So, when connecting 12v rails together, you would be circumventing this protection—which should be OK if you know what you are doing and there is no chance of a single 12v wire being treated differently than the others.

I've just had a brand new Thermaltake Toughpower 1200W Gold that I purchased yesterday burn up (literally!) after powering an Avalon A6 miner for about 30 hours. Luckily I was in the room when it went and smelt it before it actually burst into flames.

Wondering whether I just got a bad power supply (seems to be my luck) or if it just wasn't up to the job. Thoughts?
