Hi,
I building 3x 7870 mining rig, 750W PSU is enough?

have been wondering the same thing myself, seems to be some contention about it. You should checkout the hardware sub forum some good threads there. A lot of people do it but some people say could be bad for the life of components - no idea of the validity of that personally sozzle

if they are regular 7870 it's ok, if Le or Xt then they consume almost as much as 7950 ie 250W each.
