The SE III is designed for full height and a little over half length cards (7.75") and has 3 PCIe 3.0 x8 slots. So in addition to not having enough power for graphics cards such as the 1080, it also wouldn't physically fit even if you could provide the additional power. Another issue is that at this time, external GPU chassis can't be certified with multiple Thunderbolt 3 ports or multiple GPU card slots. In order to address the external GPU market, Sonnet has the eGFX Breakaway Box. This product has a single TB3 port, a single slot and the ability to power full length, double height GPU cards with an 8 + 6 pin aux power connector. Here is a link to a review of the product. https://egpu.io/sonnet-breakaway-box-review-cool-quiet/
