Thank you for your input. Here is my dilemma though:
I've just purchased a Corsair RM750e for 99.99 CAD, I had to get a Corsair 3000d with it (came in a bundle) which was also 99.99 CAD. However, the Asus tuf 850w is on sale for 129.99 CAD and I also found another case that is on sale for 59.99 CAD. So I guess my real question is, 750w A-tier psu, or 850w B-tier psu with extra 10 dollar savings lol.
