Will my PSU handle my build?

[jtmoseley]

Hello! I have a Corsair Cx750M (2017) as my power supply. I just bought as 3900x, and on pcpartpicker I'm told that my motherboard has an extra 4 pin for extra wattage on top of the normal 8 pin. I'm told that my PSU doesn't have the extra 4 pin cable. 

 

Is this an issue? Or is the extra 4 pin only for extreme overclocking?

 

Here is my build if you need to check anything out

 

P.s. don't mind the $300 AIO. It's a price placeholder for a custom loop.

it's fine, it will work. the extra pin is for extreme overclocking.

The 3900X will work fine with the 8-pin only.

No worries. The extra 4 pin will not be needed. You have enough power. Enjoy your 3900X.

As long as you don't OC manually you'll be fine. Just enable PBO and let it auto tune

Thanks, I will! I'm coming from a 6700k so it should be a huge jump in performance. I can't wait for it to arrive!
