So I've just found out that my GTS250 and 9800 GTX+ can run SLI. The only question I have is if 700w is enough to support it. Anyone here running SLI? If so, what is your wattage?

It really has more to do with the amps on the 12v rail(s) than wattage but you should be fine. I ran 2 9800gt's in SLI as you can see in my specs I ran a 700W PSU. As long as it's of good quality. Fabe If this is it it has more then enough amprage http://www.rosewill.com/products/1375/productDetail.htm

Thanks for the answer...turns out that it doesn't really matter, as my mobo supports CrossFire, but not SLI...

Good info to have for the future though. +rep.
