recomended power supply for 2 gts 250's in sli?

[SPARTAN1630]

That one's just an overrated 600w PSU - seriously, walk away. I've seen probably half a dozen sites with reputable PSU reviews, and Jonny's is right up there. Trust him (and his associates).



If you can find it cheaper than most 600-650w units, it may be acceptable, but... just no.

alright, thanks, i really appreciate the help.

need a PSU with 2 +12 Volt rails

Multiple rails are really pretty much BS; that's just the manufacturer covering for the fact that they can't handle a large load at any given point. It's a much better idea (and more and more manufacturers have been doing this recently) to just make a single, huge rail that can handle the full load of the PSU. Go for one of those. With the setup you have, I would say anything 500W and above will be fine if you get a high quality unit. Personally, my manufacturer preferences are:
PC Power & Cooling
Corsair
OCZ
Antec
...honestly, anything else I'm really hesitant to trust. Too many bad experiences.

the "hec" PSU i bauht for my origional rig was great it was 80 bucks i was skeptical too but it turned out to be a little trooper thats PSU will be good for years to come, the only reason i have to get another is because it handle the load of SLI and the 940 phenom
