Wattage calculator

[mjallan123]

Hi,

I put all my components into this:

http://www.extreme.outervision.com/PSUEngine

And it recommends a minimum of 365w, with a recommendation of 415w.

However, I just bought a plug-in wattage meter and while playing TF2, I'm averaging about 200w according to it.

Do these online calculators over-estimate the wattage requirements or is my meter under-reporting?

I'm just wondering whether my corsair ax860 is enough for a 4790k and r295x2? The calculator says 810w recommended.
