While I do agree with some of your post, you are very wrong on the PSU sizes. No current build with the exception pf a X99 system with 2 GPUs is ever going to require a 750W PSU, this debate has been fought over since Ivy Bridge. And even in a X99 scenario a 650W will be sufficient.
My 7700k build with a Z270 MB, 580, 1 M.2 NVMe drive, 2 HDDs, 3 140MM fans, led lighting and overclocked to 4.8 GHz doesnt pull more than 320W at the wall.
Now onto to power draw.
PSUs like to be used, having a 750W psu is useless in all these builds pulling ~300W, overkill and will shorten the life of the psu. Adding anything over a 550W PSU in these builds is a waste of money.
Large PSUs arent needed anymore, power requirements over the last 4 years have dropped almost 50% on cpus and gpus even overclocked, all the builds so far listed will pull at most ~300W, 500-550 is the best spot for those and even 450W would be fine, and save the xfire/sli argument, I dont think he is ever going to go that route and most games dont support it anyway. I run a 450W Gold from Seasonic on mine with 314W being pulled from the wall under full load using AIDA 64/Heaven
Even a 1080Ti added to these builds wouldn't require more than a 550
Theres other things you post I dont agree with, but I digress, not worth arguing over.
....and there is nothing wrong with a 1400, its a quad with 8 threads, perfectly fine for gaming with 4/8 threads with a simple multiplier boost to 38 and not having to touch anything else in the bios and thats on a stock cooler, it is completely able for a budget build, although with OPs budget it wouldnt be practical at $1200., however to say its useless is hyperbole, its better than a 7400 or i3 from Intel which alot of people still buy.
