6800, Possible PSU Problem?

I have had this problem a couple of times, I will be using my computer, and just out of nowhere my monitor goes blank. First time it happened I thought the monitor finally died (It's old), checked cables and such. I had my laptop right next to me, so I plugged the monitor in and it turned right on. Plug it back into my video card, nothing. Generally turning the computer off solves the problem.

Could my PSU (It's a cheap PowMax unit, 18a on the 12v line) not meeting power demands at these points, and sort of shutting the card down? I tempted to put in a different PSU and see what happens, but this problem is very random, and has only happened twice.

Yeah hopefully I won't have it for much longer. Still sort of searching, was hoping to find some one that sells Sparkle or Forton locally. No luck so far though.

Just really wanted to make sure it wasn't a card problem, which I am pretty sure it isn't, probably just some sort of fluke.

Actually I very seriously was thinking about it. I talked to my dad about it. I don't have the know-how to really design something like this, but my dad being an electrical engineer, is capable designing some plans for me to follow. However after talking to him and explaining the kind of amps I would need, he said finding components to handle these kind of amps were kind of limited. In the end he was of the opinion that I probably wasn't going to save much money, and probably just best to buy one.

I have actually run this card and setup off of a CodeGen 400 watt, and to be honest it handle it better (it ran much cooler) than my junk PowMax 480 watt. Both PSU are honestly just cheap generic units, and I figure with the amount of money I have spent on my system lately I think I should be able to afford a decent PSU. I've been using generics long enough I think! Time for something decent, and hopefully something that will run cooler.

TT-420 is a good one. I'd recommend it also since I run one too if it was on-sale or had free shipping.
