How much wattage?
 
How do I determine the amount of wattage my computer will need? What do I look at? What do I pay attention to?

look up a review of your intended cpu...look for idle/load system power draw

then look up here for the gpu : AMD Radeon HD 6670 1 GB Review - Page 20/26 | techPowerUp

and then add more watts if youve got something special going on,like a bizillion fans and so on.

All these online calculator are not so precise.
The asus power calculator ask for 550w min for my config.
Antec Power Supply Calculator
Give me 376w min, way better already.

Calculators suck and should NEVER be used.

Give us a system spec breakdown of what you have and then go from there.

Because what you'd be doing in your head is so completely different from what a calculator would do?

Question the accuracy of specific calculators, I understand. Rejecting the entire concept seems an over-reaction.

Calculators have a tendency to either gross underestimate or gross overestimate

reason for which you invest 20 dollars in a power meter and find out for real :)
