Going for another 12 card rig.
will do:
7x a5000 = 700
3x a4000 = 180
2x a2000 = 80
total = 960mh
cost = a new car

should use 2100 watts
I am finding it hard to get my hands anymore on A5000, however A2000 is relatively easy to find.
Mind sharing what brand is your A5000? mine is Gigabyte and its impossible for it to do that memory speed.
