Psu calculator that makes more sense than most

[ted34]

Most psu calculators always report low figures and dont have the right hardware listed. I just put my system into it and came out making sense. Add 30% though to have some give

That recomends me a 400w psu and my system barely uses 200w. Its way out.
Its a good way to calculate a comprihensive maximum power but in reality its impossible to draw maximum power from everything at the same time.
If you get a psu with the recomended power it will certainly be plenty.

But thats what you want. If you buy a 200w then it wouldnt be any good in your system though
