I am in the process of doing my first mining rig build and you have been a big help thus far. I thank you for that. However I do not know the best way to put it all together. I tried searching but found no good source. Do you have one? Once I can get a process down I intend to build 3 or 4 of them. All of my rigs will be 4 cards. Starting with GIGABIT 750TIs for my first. I see it says 400W in the specs so does that mean that I need a 1600 WATT PSU? Sorry but I am rather much a noob at this.
