Hello!

I have a semi-old FSP Aurum gold 700W PSU and I am planning on doing an SLI with the Gigabyte Windforce 770 4GB's. I have one of the GPU's already and bought it planning on SLI (before I really understood what I was doing).

I've seen mixed reviews on whether the 700W PSU would cut it, and it has been constantly used for about three years (no issues). The aim here is mostly to prevent the need to get a new PSU since at that point I might as well start looking at the 980 for cost performance.

Thoughts and suggestions are appreciated! I've used this site alot to get advice on components in the past :)

Normally, dual GTX 770 require a 850W PSU for sufficient headroom. But if this is your PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817104099
...it has a strong 672W +12V rail. Both cards maxed out would be somewhere in the neighborhood of 460W. If the PSU has the necessary 6/8 pin connectors, I'd be inclined to use it if it were mine.
As far as the age, I would not have any qualms about using it at 3 years old as long as I knew it was well cared for and not abused. The one in my sig is older than that.
