Ahh, I see. At first I was very puzzled by this, that can't be true. It is a safety feature. It will cancel the print. It does, but unless your printer can shut off the power supply (or at least power to the heatbed) then it wouldn't do any good. Thanks for the clarification!

Is there a thread about using a ATX power supply and how to wire it? I am thinking about switching power supplies and I had toyed with the idea of a computer power supply. I'm not too keen on the extra steps needed but if it is safer/better it may be worth it. The power supply I linked to earlier is 36amps but appears to be better quality. It is $80. I can get a morepowerful ATX power supply for less. If it also works better...bonus.
