compatibility mobo Motherboards Compatible with SLI of 3 slot GPUs

[jwakeford]

H I'm in the market for an SLI of 1080s. 
The Gainward Phoenix Goes Like Hell edition ( GLH ) caught my attention, as did the 1080 Xtrem gaming from Gigabyte, but those are 3 slot cards ! 
Would they fit an Asus Z170-A   or a Asus X99 Strix  ?   

Thank you for your input

If the PCIe slots have a spacing of 2 slots in between them, it'll work.

I would avoid the z170-A however, its a rather thin PCB, even sags with my single 980, could only imagine what 2 3 slot cards would do to it.

It needs to have 2 slot spacing between the x16 slots in order for your triple slot cards to work in SLI. Want breathing room, then it needs 3 slot spacing between the x16 slots. Strix X99 is the better option.

With that out of the way, Now you will need to find a really long HB-SLI bridge.

Yeah, I dunno if the XL ones are out yet ... 
Otherwise I'll just use two classic ribbon style bridges, it performs the same basically.

The RGB ones (light up in orange) are the slots, where the gpu goes to. So 1st GTX 1080 goes into the 1st x16 slot. With it taking up 3 spaces, it blocks off the x1 and x16 (the one without RGB). 2nd GTX 1080 goes to the middle x16 . This leaves no breathing room. For breathing room, 2nd GTX 1080 will need to go to the very bottom x16 slot. So with SLI, you need a bridge with connectors, that has it at the very top slot, to the very bottom. The HB bridges are different from the standard ones.
