I recently bought a GTX260 from Newegg for about $200 and I figure in a couple weeks to a month, I can buy another video card should I need/want it. (i.e. another GTX260 for SLI). My PSU is a 700W Silverstone Strider unit, and it has served me pretty well. In my computer I have a Core i7 920 overclocked to 3.2GHz (it was a lot higher until I got some more DIMMs, then I had to lower my overclock, but honestly in everyday use I don't notice the difference much).

Would my power supply be able to handle it? It is SLI certified, and has enough leads for 4 6-pin PCI-e connectors, which I believe would be spread across different rails, however I would need to open up my case and look to be sure.

Also my video card is overclocked, per the specs in my sig.

Thanks. I don't know much about SLI and I hear horror stories about how you apparently need at least 1KW before you should consider SLI with these cards, but I am not so sure I believe that.
 
The ST70F is a bit weak on the +12V rails for a 700W unit, but it will be enough for your rig with a second card, especially if you grab one of the newer 55nm GTX260s.
 
Thanks. Didn't realize this should belong in the PSU section.

I thought there might be a reason why the ST70F would be as cheap as it is (compared to other similar PSUs. I guess I know why now.

I think I have one of the 55nm cards already, which would be nice if it is the case, (I am kinda sure this is the case as the backplate is not there), although I don't know if there is a way to tell for sure.
