how do i?

[Gentlekatt]

Hello, guys how do i check how many wats does my psu have without checking back of the case?

[Tedster]

By checking inside the case, which is usually where the PSU stickers are?

 

Do you have an exact part list?

[SirRoderick]

Check the box.

 

You can't read it from the OS or anything, needs to be the specs on the PSU

(in all seriousness, check the label on it! tell us the make and model)

[amintha1992]

i hate totally non descriptive titles. 

 

with that out of the way,

 

we can not tell with out a specific model,

 

check on the PSU or on the Box it came in.

1) Get a wattmeter and plug your PC into it

2) Start overloading your PC with power-hungry GPUs (like 295x2), one at a time

3) Find when the power input stops being sufficient

4) Round the number
