Aight... so I know this is annoying, but I've checked multiple PSU calculators and asked several people, and I get all kinds of mixed results. I'm going to swap out my TitanX for 2 EVGA superclocked 980TIs. I also have an overclocked 3770k pushed to 1.30v. 1 SSD, 1 HDD, and 1 Blu-ray drive. One calculator said I only need a 750w power supply (to be on the safe side) and another said I would need 900w. Forum posters here and there also suggest that I would need 850w, but that I should get a 1000w power supply just to be flexible in the future. Others say I don't need more than 650w. Here is my current PSU. Is that enough, or should I get more power?
