Good supplys will distribute the power load across the rails but can overallocate power requirements which could be used elsewhere, single rail supplys dont do that.
no it doesn't consume 24A (did I say it did?) but its not the only thing running, the GTX 460 uses 160w peak load, about 13.5A, the i5 uses about 180w under load (15A) then theres everything else that needs power
we really could debate the point all day, even the industry is split as to which is better
but when it comes down to it, what are the drawbacks of having a higher rated power supply at the same price?
you only use what the machine draws and maxing the supplys capability will increase deterioration and reduce the lifespan, it will also limit the potential for upgrading in the future

Again, any good quality PSU will not have any issues with overloading anything. A stock i5 750 certainly does not consume 180w, not even close. The only difference between Single and Multi rail PSU's in the lower wattage range (<550w or so) is when and how the OCP kicks in, nothing else. The whole rails overloading problem existed a few years ago on older PSU's, not now.
As for drawbacks, you can end up getting a lower performing PSU, in terms of electrical noise, ripple supression, voltage regulation, rated ambient. A PSU is the most vital part of your PC, getting a great performing one instead of an average/mediocre one can mean the world of difference if anything bad was to happen.
I didn't actually recommend a 450w either, I just said that a 450w PSU will actually work fine, I recommended a 550w unit and two 520w's, which is enough to power a single GTX 480.
Also, it would not be anywhere near to maxing out a 500-550w, under BOTH Prime95/LinX and Furmark or any other stress tests you may use, the rig would not exceed 400w if not overclocked. Under general gaming (which doesn't stress a PC anywhere near the amount that stress tests do) it would not exceed 350w.
Lastly, all PSU ''calculators'' are innacurate.
These are my recommendations:
Antec 520 Neo ECO
Antec TPN-550 or 650 if you
really wan't that headroom
Seasonic S12II 520 or 620. Modular versions of this PSU are M12II-520/620
I'm not trying to start an arguement with you or anything, but I am quite strong on my PSU knowledge.
