[SOLVED] Can I have EPS extension 4 pin unplugged?

[gilgamesh2134]

I just bought Asiahorse extension cables and my motherboard allows 8+4 pin EPS but the extension is 8 and 8 pin. Can I plug in all 8 to extension for the 4 pin and just leave the other 4 pin sitting unplugged? Or should I only plug in 4 pin to extension and leave the 4 pin extension unplugged?

That surely is confusing question. I'll try my best though.
You should connect full 8 pins between PSU cable and extension cable. The extension connector that goes into motherboard should have only 4 pins plugged in for the second cable, with the other 4 pins just hanging unplugged.

You can leave anything beyond the first 8 pins unplugged unless you plan on doing heavy overclocking with a 100W+ CPU.

Those answered my question exactly, thank you!

Yes and no. Depending on the motherboard and cpu. Some motherboards demand a 4+4+4 for a 9900k or better, some don't, only requiring the 4+4, same goes for the 5900x/5950x. Applies to cpus as well, they might demand use of a 4+4+4 if heavily OC'd, with restrictions to clock speeds if just supplied by a 4+4.

So things will need to be done on a case by case basis, there's no hard and fast rule that says yes or no for sure.
