Subject. I am currently planning to upgrade my motherboard to an SLI motherboard. The reason I want to do this is because, in case I want to upgrade the graphics power of my motherboard, I can simply buy a second GTS 250 and give a quick 50% jump in performance.

My PC currently has a 600Watt OCZ StealthXStream.

 
The GTS 250 is a g92 based card and is typically a 55nm version. I know the GT and green spec of the g92 very well in terms of power and performance. As for the full spec G92 will likely fall around the 85-120w range per card depending on core voltage and clocks. Avg load should be around 100w for each card in sli so it is on par with the power figures of a single gtx 465/gtx470. A high quality 550w unit (80%+ gold rated unit) or a typical 650w 80% rated unit that isn't even bronze rated. Look on newegg for examples.

Why does it matter if it is Bronze only Gold 80% rated?
 


That figure is off, that is less than what two normal 9800gt will draw at stock clocks and roughly the same of two green edition overclocked. Never bother with psu calculators and I prefer to factor in max load or avg load figures that are physically measured in reviews.
