  1. An 850W unit is fine,you could just get a 750W which would be enough power too!
    If budget allows for the 850w,go for it.
  2. rosewill rx750-s-b $89.99. 750 watt PSU should be good.

    Rosewill is kind of cheap quality-wise
  4. Go for the 750w, it'll be futureproof because we're inventing items to use LESS power, rather than more :)
    But make sure it has the rite ammount of conectors for your twin GFX :P
  5. instead of 2 560ti a single 570 or 580 is better, and will use less power

    for your current system a 750w is minimum, but 850w is a better choice with minimum 650w-700w on 12v rail (combined).

    For 570 you need 600-650w psu

    Dude stick with Corsair or XFX = both good quality and carry 5yr warranties.
    Where do you shop?
