3 way SLI. Whats needed?

post #1 of 13
Thread Starter 
Someone pointed out that on Nvidia's website it states that the 650 Ti Boost and 660 can do 3 way SLI but i've only seen PCB's with 1 SLI connector. Do you need two for TRI or could you just use a 3 way bridge and connect 3 pcb's with 1 SLI connector?

Single SLI Connector

Single SLI Connector

Do you have a link? Everything I have read says650ti boost only does 2 way sli. I am pretty sure you need 2 connectors to do 3way or 4 way sli. I was unable to confirm any information on nvidia's website.

You cannot Tri-SLI those cards. GTX 660 or GTX 650ti boost = No Tri-SLI


Only from GTX 660ti and up (GTX 670, 680 etc) that can be Tri-SLIed and Quad-SLIed

Ait 5770s came with single connectors for crossfire, then all of a sudden some came out with two connections making them be able to do tri-fire.

I'm sure there needs to be two connectors for more than two-way sli.

I'm sure it's intentional. In supported games and a good deal on 4x 650ti boosts you could blow a titan away for 600$. lol.

Anyone with 670 3 way or 680 3 way care to undo 1 side of the SLI connector and see if you could still enable SLI?

Here's the Link

I think it's a typo on nvidia's ad copy. The only info I can find on 3/4 way sli is on the 660 ti version which does have 2 connectors.

All the 3 way sli connectors I have seen or can look up are double wide and require 2 connectors per card. I am pretty sure it is required.

Has to be a typo, the 650 Ti Boost says the same thing.

If only it wasn't a typo. 3 way 660s would be a great deal of performance for 567 dollars
