Some of the PSUs suggested so far are insufficient.
Hi again
last time I bring up this thread I promise lol
Now I have some cash I am looking to invest in this..

My calculations say this will give me 40 amps? Can some reassure me please?
Thanks
Minus the CPU you will only have 16A (at max) so lets say 15A (running at almost 100%), to power a graphics card that requires up to 11.6A just by itself. That means if you want to run anything else on the 12V rail, it must be under 36W. Thats at 100%. That PSU will fail.
The same goes with the rest as these psus do not have EPS certification, meaning that under ATX design standards, 12V2 is dedicated to the CPU. Thats the first 16A on the 12V rail. That leaves 16A for everything else, mind you at 100% = poor efficiency, heat, expensive and shutdown (and associated damage).
You need a minimum 12V rail of 26A on a quality EPS 2.91 certified, 80% efficiency on a strong single rail. Go for one with 5 years warranty. Do this or risk losing much more than your graphics card.
Cheap PSUs are false economics.
