I currently have a gtx 760. i was thinking about getting a second one and using SLI connection.I have a 550w psu and was wondering if i would need to get a better one in order to run 2 760's. Heres a link to my PSU http://www.amazon.com/gp/product/B00918MEZG/ref=oh_deta...

Absolutely. What is your CPU and RAM?

Yep, a single 760 is probably putting you pretty close to what your PSU can handle.

The GTX 760 requires 30 amps on the 12v rail, that PSU has 45, so you are no where close to using the power that one has. But to run 2, you will need at least 60, so for 2 760s that psu will not do. Your probably looking at getting something around the 750W - 850W range to get the required amps to be able to run those 2 cards together. IF you need a recommendation let me know, otherwise look in that range for something from Corsair, Antec, Seasonic, XFX, etc.

A single 760 won't even come close to stressing that Seasonic unit, I have one of those in my backup ITX system alongside a stock 3470, an overclocked 660 Ti and 8GB of ram, and the unit barely breaks 200W of power consumption. While the PSU is technically well able to push two 760s, It doesn't come with enough PCIe power cables for that kind of setup. At best, you could run 2x660s since those only require one 6 pin connector each. So unfortunately, you're probably going to want to upgrade to a larger capacity PSU, especially since doing so will give you not only the required amount of power connectors, but more headroom to overclock if want to. However, at that point with the amount of money you'd spend on buying both a PSU and another GPU, you may want to just save up to get a powerful single GPU like a 780/Ti, since that'll get you around the performance of 2x760s, but with less power consumption, and more flexibility to upgrade in the future.

*Edit*
If you really want to go the SLI route sooner than later, I'd go with diddy's brand recommendations; go for something like a Seasonic X-750 or 850, or for nearly the same quality but for slightly cheaper, go for an XFX PRO Black edition 750W or 850W unit.
