Although these will work only on Geforce GTX 1080 and GTX 1070 graphics cards, the EVGA SLI HB bridges will be available in three different versions, depending on the gap between graphics cards on the motherboard, including 1U, 2U and 3U versions.
The new EVGA SLI HB bridges from will also have RGB LEDs and will be able to sync with EVGA's GTX 1080 FTW and GTX 1080 Classified graphics cards for some color or just shine in green or white to match Founders Edition and other custom GTX 1080 graphics cards.
As you already know, Nvidia has focused on 2-way SLI with new GTX 1080 and GTX 1070 graphics cards so EVGA is doing the same thing.
The new EVGA SLI HB bridges will be probably sold separately, similar to the previously available EVGA Pro SLI Bridge.
