Here's a couple of tutorials if you want to read up on power supplies, some short, some long.

Minimum of 750watts, 850 would be better.

Thanx I was thinking about that Corsair myself. I also found this one sounds like its got some power and some nice sounding extras!! 1250 watts might be over kill if im looking for efficient?

Overkill, but it gets great reviews. Make sure your case has room for it.

I have a small TIG welder that uses somewhat less power... Maybe I could sub in this unit and move up to 5mm welds vs. my present 2.5mm welds...?

That review just made me want it more!! So tell me, what is bad about overkill??

 

[masterjaw]

IMO, overkill is when you buy more than what you really need/use. corsairs has 80+ % efficiency. 850 is quite enough for your system.

Ok SO im thinking the Corsair but is it a problem that it has only 1 12v rail? What is the benefit of multiple rails?

 

[dirtmountain]

You didn't read the tutorials !

"Some manufacturers decided to implement one over current protection (OCP) circuit for all +12 V wires, simply trusting the fact that is highly unlikely that at any given time a single +12 V wire would be delivering more than 240 W on a PC power supply, because of what we explained on the previous paragraph. This approach is called single-rail design. In fact some power supplies, especially very low-end ones, don’t have any OCP circuit at all"
