Will a 750 w power supply be sufficient or should I consider 850 w

Title says it all. Would rather ask for real hand experience then go by the estimated wattage pcpartpicker posts.

  1. Most people on this forum will tell you that with a GOOD 750W PSU, you can easily pull off SLI 770s.

    Personally, I went with an 860W PSU as I feel more comfortable, so the ease of mind was my reason for going with 860W.

    Depends, a high quality 750w unit would be ok, but a lower quality one wouldn't. Personally I'd go with a good 850w psu to make sure I had good amount of headroom. Also If you want 16GB of ram get 2x8Gb sticks instead of 4x4Gb.
    Here's an example of a good 850w PSU
  3. So a Seasonic 750w gold rated would suffice? Whats the benefit of having 2x8Gb sticks when the 4x4Gb are cheaper
  4. With 4 sticks you may have to play with voltage and timings to achieve stability. The price difference isn't that much.
  5. A quality 750w at a great price.
