Default PSU wattage

Assuming enough amperage, and 3 rails at 700 watts, is it possible to do either crossfire or sli? Or do I need more power?

Thanks again for all the support.

If you intend to run anything that's a high end graphic's card like the 4780 or the 260 or card's like those, I'd suggest a 800-1000 watt just to be on the safe side.

you would need 850- 1000 for 3 of the high end cards like the 295. I think 700 would be good for 2
