I have 2 GTX470s running SLI perfectly but I want to add another one (they all are Superclocked editions) and I was wondering if my OCZ Z-Series 1000W 80+ GOLD Certified EDITION could handle it with my 4.0GHz i7-860? Im running all of this in a MSI Big Bang Trinergy.
Should work. I calculated it using values that I guessed on, but I tried to be as pessimistic as possible, so that it was the worst case scenario. Anyways, your PSU should do fine. Worst case scenario is you encounter instability, and need a bigger PSU.
You have plenty of power for that the OCZ Z-series is a great power supply.
Are you sure? Im quite scared since the 3 GTX-470s would be the Superclocked editions and my Big Bang Trinergy with my i7-860 OC 4.0 GHz can draw almost 275W alone...the good things is that I only power those and 1 HDD, one Corsair H50 and a simple DVD-CD Drive
