I'll answer again. You need 60mm. Each slot is 20 mm apart, each GPU is 40 mm thick. You have one 20mm space between cards, or "1 slot".

Shaman got it in before I could.

Sorry, Scarlet.  I'll go slower next time.

Great thanks.

I ordered this one since the HB ones are out of stock.

What is the difference?

This is not the new SLI HB bridge, it is just a LED bridge.
There are some differences:

cancel the Amazon order and wait for a High Bandwidth bridge to become available. use the ribbon cable sli bridge that came with your MB until then.
 
 

Why buy a bridge that will limit what you can do?

TPU present NVIDIA GTX1080 SLI ...
 
https://www.techpowerup.c...ce_GTX_1080_SLI/1.html
 
70fps on 4K in Crysis 3, 77 fps in Far Cry Primal, 95 in GTA 5...
That mean GTX1080 SLI should be option for gamers who bought 4K monitors and want to play in native resolution.
One thing is very important, fps is almost double compare to single GTX1080 and looks like NVIDIA really
optimized better SLI in games with this generation and because of that they limited GTX1080 on SLI configuration.
 
 

thanks, this info really helped.

So it would appears the HB bridge only works on 16x16?
 

I thought it worked independently from the PCI lanes and it's a direct connection?

hey guys have any one tried this bridge with the EK-FC1080 GTX? does it fit?

It should I am currently using the 2/3way EVGA SLI bridge which is the same size on my EK FC 1080s and it fits just fine.
Now just waiting until the HB 0 slotted come back in to stock haha

why is the 60mm never in stock :/

 
because it hasn't been released yet.  They initially stated early July, but they are still waiting on the bridges to release them. 

Are there any difference other than looks between the Nvidia HB bridge and EVGA's? My Nvidia bridge arrived earlier than my 1080s did and it's just sitting there.

One thing i've noticed when testing bridges is that when the elastic bridge is connecting 2x 1080's, in the nvidia control panel it gives the message 'using a high bandwidth SLI bridge would improve performance.' Or words to that effect. Then when you put a HB bridge in the machine, that message is gone. But the interesting part is, i have this EVGA bridge also: http://cdn.overclock.net/b/bb/500x1000px-LL-bbba247d_ProSli.jpeg. The EVGA pro SLI bridge 3-way (the one on the right in the picture). Its not a HB SLI bridge but because it connects both SLI sockets on each of the 2 1080's, the nvidia control panel sees it as a HB bridge and doesn't show the message telling me to put in a better one.
 
I've tried benchmarking both the HB SLI bridge and the EVGA LED 3-way SLI bridge and both are yielding very very similar results - only a few points discrepancy in Firestrike Ultra between them.

is there some possibility that this bridge will improve performance even on a GTX980 Ti SLI?
I'm using the old EVGA Led Bridge, should I upgrade to this one with a GTX980 Ti SLI?

No and No.
Only Pascal generation see some improvements in 5k resolution and Surround config.

Just came in today, expect to see them shortly.

0 and 1 in stock http://www.evga.com/Products/ProductList.aspx?type=14&family=SLI+Bridge&chipset=HB+Bridge 

 
And...the 1 slot is gone. Looks like I missed it.
 
Hey Jacob, will newegg be getting these soon? If so, do you know what day?

Got lucky and got a 1 space today.  Arrives tomorrow....nice.

Are the HB bridges going out to retailers anytime soon?
