CoolerMaster PSU Calculator!

[MUff1N]

It's the Cooler Master PSU Wattage calculator...
Make sure to click the Advanced tab which gives you much more options on what's going into your system.
I'm sure it's not 100% accurate, but it does give you an idea of what you'll need.

I was surprised at the power requirements for my system.
Seems right now I'm around 200 watts over what's needed! Nothing wrong with too much power!!!

I just did my CPU to see what kind of power it's using OCed at the vcore I have it set to as seen in the screenshot below.

Btw, only half of the page is showing so there's a ton more options that
aren't showing including using water-cooling in your setup.

I've also used this site in the past to determine what my PSU needs are. And like you, I too have too much power supply for my needs. I think that is a think with techies...we generally tend to overspec what we need. When I was building I knew the 520W Corsair would be MORE than enough...but even then...I just went with the 620W to be sure.
