[SOLVED] Can the PCI-E 8 pin be used for the CPU 8 pin connector?

[reapzstar]

Hey there!

Unfortunately my PSU(Seasonic Prime Ultra 650 Gold) doesn't have an additional 4+4 pin CPU connector.
I'm currently using my mobo with just the 8 pin plugged, which for my currenct CPU(i5 12400f) is just fine, but I'm planning on upgrading and I'd like to have the additional 4 pin CPU plugged in as well.
My question is, could I use one of the PCI-E 8 pin connectors instead of the current 4x4 that's plugged powers the CPU and just connect one of the two 4 pins in the other one?
I wouldn't want to upgrade my PSU as well, since the new CPUs cost a fortune around here, if this is a possible method.
The motherboard is an ASUS TUF B660M PLUS D4.

Thanks in advance for every answer!

Regards,

Richard

No the pinout on the PCIe plug is not the same as the CPU power pin out. If you are going to spend a lot on a new CPU, then buy the proper power supply to use it.

Your PSU has 5 sockets for CPU and GPU cables. Buying a second EPS cable is the easiest way.

What's your GPU?

I'm not quite sure where to obtain one of these in my country, probably close to impossible.
It is an RTX 3060 Ti

Edit: I found one on aliexpress for pretty much the same price, ordered it.
Thanks for your feedback!
