RTX 2080Ti in the AORUS gaming box  

I'm going to try to to disassemble my 2070 AORUS gaming box enough to accommodate the eVGA RTX2080Ti amp. To start, it will be ugly and possibly thermally throttled, but I just want make sure it will work electrically first. Aside from another power supply (the eVGA needs 2x 8-pin power and the gaming box only has 1x), any tips?

Also, does the 1080 in the gaming boxes have NVLINK ports for SLI? I noticed a connection where SLI bridge could potentially fit. It's missing from the 2070 card. 

UPDATE: Well, I can't get the card to power up, despite the extra power supply powering the card and the AORUS board/PCIe slot. Because the 24-pin main power connector blocks the card, I'm using a Thermaltake 200cm PCIe riser/extender. I think the AORUS board doesn't like that.
