PSU CPU cable

[Hermann]

Hey guys I was just wondering do I need both of the 4pin CPU connections to be plugged into my motherboard for the CPU to work properly or not. Can I just plug in one four pin connector?

 

I have an Asus X370 Pro

And a ryzen 1700x that will be overclocked

What CPU would that be? You might be okay using only one, but you can definitely forget about overclocking or doing some heavy work on the given CPU.

 

I also can be wrong.

What PSU are you talking about?

But those two 4pin equal one 8pin and you should use them, especially if you plan to overclock.

Going off the PCIE specifications I was looking at a while ago (and making some assumptions) I would say you should basically account for 18.75w per pin. So on a 4 pin that would be 75w, although I expect if you looked you would find the socket has addition power from the 24pin. Being as the TDP of the 1700x is 95w I would say don't do it.
