A:Answer The answer is yes, it will fit. I have an Alienware Aurora r8 that I purchased this rtx 2080 ti xc ultra for. Installed it and runs amazing! The only thing is it is super bulky so you probably can’t fit a second gpu in it if you have this one installed. If you haven’t already, change out the stock fan for your aurora r8 with a Corsair 120mm led( like $30 at bestbuy) and change out the stock cpu fan/heatsink with Corsair h60 cpu liquid cooler (can find it at bestbuy for $80, compatible with the i7 on ur aurora r8). My Aurora r8 is now super quiet /cool while under video game load at max settings. Hope this helps! Oh and I almost forgot, if you have the stock 400w power supply unit, you will need to change it out before you install this rtx 2080 ti as it requires more power. I took my stock Aurora r8 psu and upgraded it with a Corsair 850w( bought it for like $120 at bestbuy as well)
