No. The motherboard does not support it. SLI requires two PCI-Ex16 slots, both running at least x8 throughput. Your motherboard's second PCI-Ex16 slot is only running @ x4. SLI is not supported.

No, you'll need a better PSU.

If that is the Extreme Power Pro model you don't have enough PCIe cables (and I'm not aware of any 600w CM model that does).

For SLI Gigabyte 760's you'll need a PSU with 2x 8-pin and 2x 6-pin PCIe power cables and ideally a tier 1 or 2 PSU at 650w-750w.

Here are two very good choices for PSU upgrade at the moment for reference, both have the correct wattage and PCIe connectors that you would need:

Power Supply: XFX TS 650W 80+ Gold Certified ATX Power Supply ($44.99 @ Newegg)

Do not select Best Answers to threads you did not start. Always follow these rules:

Selecting Best Answers is a privilege, left to the originators of a thread. You have the ability to select Best Answers because you've received five Best Answers yourself. However, there are rules for this (and we know, they're not clearly laid out).

1) Under no circumstance are you to select the Best Answer in an active thread you did not originate (active meaning answers within the past two months).

2) If the original poster of the thread has selected a Best Answer, under no circumstance are you to change that selection.

3) If a Best Answer has been selected by a member of Tom's Hardware and is clearly wrong, you may then select the correct Best Answer.

4) If the original poster of a thread has clearly marked an incorrect Best Answer, see rule #2.

I think that covers everything. For the most part, we recommend that you simply ignore the feature (except in threads you've started).

Ok will do.but yes the vote system is floored you either have non voters not rewarding for your efforts or others vote for last answer which only elaborated on what you had said before them. Too many get credit they just didn't earn. you answer first with what ended up being correct but they got the damn credit :p

On top of that, NVIDIA has a very distinct set of requirements that a motherboard has to fulfill, in order to be allowed to have SLI. It's not just a case of 'just slap this microchip on there and bob's your uncle', there are requirements to be met and there are licensing fees to be paid by the manufacturer. Yes, NVIDIA actually has the manufacturer pay for the right to implement SLI and use SLI as a selling point. NVIDIA wants tight control over SLI, partly of course because it's their own development and it's also their name that is on the line if things go wrong with it.

Compare that to AMD and Crossfire, who don't have a whole lot of requirements. AMD just wants it out there.
