really? The rig has 8 gpus. I assumed the power consumption is for all 8 gpus?
And looking to your specs that you wrote here, i can tell you are a hardware noob. Before start, you`ll need to read about how to mod your cards. Youll need another bios on those 580.
My advice is, dont start with all 8. Install everything(windows), MOD all cards separately, and then filll your case to run! Go slow!
Thanks for the advice! I do feel kind of lost right now!
