Original Question:
I'm planning on building a new PC and I'm not sure which PSU I should go, a 850W or 1000W (Corsair's RM850/1000X). Reading other people's questions on this same topic, I found somewhat mixed answers, others saying 850W should be just fine for this type of build, and others recommending strongly to go for the 1000W just to be sure and to hit that 50% usage sweetspot performance. Do you guys have any suggestions to add? Is the 850W be perfectly fine or should I just pony up the 50 bucks extra for the 1000W and never worry about the power supply ever again.
