So I have a corsair cx600m 80+ bronze PSU and I was wondering if it has enough watts for a Asus Gtx 1080 Strix 8gb edition? https://pcpartpicker.com/list/
I am not planning to overclock the gpu
 
Solution
Well with a single 1080 and a usual system, it is unlikely you will draw over 600w.

However for your GPU it will be pulling its power from the 12v rail. Also along with other 12v items such as your CPU.
So what is important is the rating of the 12v rail.
So according to the CX600m's specs on this page: https://pcpartpicker.com/product/sCH323/corsair-power-supply-cx600m
If you look down at the outputs you can see the 12v rail is capable of 46 amps.

Which means, due to Power(watts)=voltage*current(amps).

That PSU is RATED to be able to deliver 552w of it's 600w through it's 12v rail.
So therefore since a gtx 1080 can draw 180w peak (not accurate), say 130w for the CPU. You're at 310w+what ever devices you have. ~410w (once again do not...

So you could even overclock.

So short answer yes you'll be fine running your system 😉

edit: Note, it isnt what your system pulls on average while under load that is important. It is what it possibly could pull at peak. e.g. A GPU pulls 130w average, but peak figures are at 150w. The power supply must be able to accommodate for that.
