Ok so say a system has these specs:
a core 2 duo @ 3.0ghz
2gb ddr2 ram
8800GT
2 Hard disks
2 dvd-rw
3x120mm fans
draws 281w with psu calculator below.

Even if you put a overclocked 8800GTX it only reaches 336w.
So why do we need a psu with 500w and over recommended for such systems? I do understand though just having a 500w psu doesn't mean all of that power is useable but wouldn't a solid 400-450w psu be enough?
Like if you were to have an SLI system and depending on other components then it would draw a lot more power.
I'm not trying to saying that we don't need powerful psu's or anything I'm just trying to understand how things work.
I'd appreciate if someone could explain this to me, don't need to go in-depth.
Also could anyone care to just briefly list how much power each component takes like
processor, ram, motherboard, hard disks, optical disks and so on - how many watts each of them take or are there any good guides or articles out their worth reading to gain more knowledge.
I have found these two below which I found useful
