Hello,

i have a working eGPU setup but I want upgrade my GPU to a GTX 1080. Actually I run a Mac Boom Pro Late 17" 2011 with the Akatio Thunder2 and a GTX 1060 with the DELL DA-2 Power Supply without any issues. Can i run farther this Setup with the GTX 1080 (Specific Zotac GTX 1080 8GB Mini)? Or   I must upgrade the power Supply too? I am not really sure...

You'll likely need a beefier PSU to accommodate the GTX 1080.

Also, I would not bother upgrading to a 1080 with TB2 and a 2011 MacBook, I'm pretty sure smarter folks than me will correct me if I am wrong, but it'll bottleneck way too much.

First, thanks for the realy quick response and recommendation Smile

I don't think that TB2 will be the real bottleneck (in my case) i mostly use the GPU for Gaming and about GPU-Z the Bus usage its mostly below the 50% I think so, but I will check this the next days. I will think the plan, but it should safe enough to try.

My recommendation for an alternative power supply is a SS-350m1u. I use one to power a more power hungry 980ti. It's very small and also modular.

I'm using 650W with my EVGA 1080 and when i run some benchmarks i got coil whine.Started googling it and it turns out that the proper PSU should be 850W(or you got coil whine,if you go bellow 650W it might be even worst) for them.Those 1080's are power hungry beasts,i can tell you that much.Also they are very sensitive,i just changed all the outlets in the living room of my apartment due to being old(that's one thing) and the driver was hanging(not crashing but just stops working and can not recover),and was doing that when i wasn't doing nothing on my laptop but just walking around the room.Took me awhile to figure it out,i thought i got defective GPU at first.What i'm saying here is don't underestimate that beast and get yourself a proper PSU.

Hey Guys in the last days I tried it out. And Eightarmedpet should be right Smile the CPU is a too much Bottleneck for the GTX 1080, but the Bus has still enough space. GFX Benchmarks was ok, in compare to the GTX 1060. But in Games like Battlefield 1, Star Wars Battlefront. This System will have no more advantages, ok that not really right you have almost 10 FPS more, its a lot quieter then the GTX 1060 and its feel a little bit smoother, but its not worth it. I tried everything. New Windows on a second Partition, Newest Drivers and some older Drivers, in game the result will be the same. 

For interesting Guys. the Bench results but in game no much difference.

@victorios can you do 1920x1080 on Superposition 2017 and post the results(screenshots),just need to compare it.Thanks.

P.S. How could it not worth it? You gained aprox.30 FPS(3440x1440) and 60 FPS(1920x1080).Is that nothing for you?

The GTX1080 has a mass of power but this power cannot be unleashed with my setup INGAME like Battlefield 1 and so on, The Heaven Bench Tests the GPU the results are still good, but Games has also as a relevant usage of CPU. My CPU is Bottlenecking the GTX 1080 and for 540€ for only 10 FPS more in games in compare to the GTX1060 thats not worth. And I tried every thing from Installing Newest and some older drivers and a new Windows installation on a Second Partition. the Results still the same.

I have send the GTX1080 back. so I can no more testing. Sry, but like I said around 10 FPS more in games for 540€, 54€ per fps? That will be a wast of money.

Just curious, with Thunder2, how are you able to run GTX1060 with 6pin reliably with only 75W from 6pin cable and PCIE slot (about 25-30W)? GTX1060 as I measure can go up to 120W. It will need more than the supplied power, panic and reboot.
