More about what
  1. 600-650watts will do just fine running a single GTX580! Looking at the brands you have chosen so far you will not have a problem selecting a quality unit that fits your budget.
  2. what about 2 580s will a 750 cut it? or no cuz im looking at the corsair tx650. and for $10 more for a tx750

    lets say 2 580s i can get a seasonic x750 or corsair hx850 for same price.. need suggestions
  3. 750 would if you do not overclock or stress test! If you are planning that I would go with the HX850 for headroom.
  4. okay perfect!
  5. how does the tx750 do for sli 580s?

    ORRRRRRRRR


    Tx850
  6. Alrighty.. so now the choice.. Corsair TX850.. Or the Corsair HX850 big price diff. i dont really care much about the modularity
  7. TX850 if modularity is not preferred!
