Did you miss the part where I said you distribute the load over each rail?
uh huh

well if the psu is capable of self-distributing the total amperage across 2 or more rails then wouldnt that make me trying to distribute the loads evenly among each rail redundant ? -

No...as an Asian you should understand how electrical circuits work...if you share a single load on multiple circuits those circuits can be built with less load bearing materials...1oz copper traces instead of 2oz traces etc.
ETA:
Your home for example...you might have 1 100A line coming into the home which is then split into multiple 20A circuits...you can still load your home upto 100A...as that's the main line coming in...THAT'S how the PC PSU works too. -

not if i have 3phase 100A power lines. -

i'll fully admit i'm like really dumb but like uhhhhh you know the socket that your standard 60w incandescent filament lightbulb gets screwed into is running 120v right? underpowering an incandescent bulb would make it last longer if anything... neh? -

Originally posted by Jiggaboo_Johnson Then your load is distributed over 300A…duh.
exactly. thats whats happening inside a psu.
a british psu will be getting a supply of manly 240v @ 13a, which translates into like 3120w, five times more than what a psu outputs in its entirely.
the thing your missing is that PSUs are step down transformers, and theyre outputting less than what their inputs are. and because of that the maximum load on one rail doesnt amd will not be equal to the max load of their inputs
a modern psu will have up to 4 rails of 12v30a, which means it can produce up to 1400w in total. just because you load up one of the rail with 100% load doesnt mean youve utilized the psu's full load capacity. -

o, i thot you meant 9volt 60w bulbs. -

As you noted..there is more than one rail...
The mobo, gfx card, hard drive, ram, etc...pull from multiple rails...stick 2 graphics cards in if you like for 400W draw goodness.
Give it up Asian, you're out witted and out shitted. -

yeas, and the loads arent distributed between these independent rails.
The mobo, gfx card, hard drive, ram, etc…pull from multiple rails…stick 2 graphics cards in if you like for 400W draw goodness.

errr, im sure the rams are pulling from the same rail that goes in into the mobo.
also a basic graphic card isnt going to work as hard as a gayming graohic card.
or an ssd as hard as liquid state drives.
