Need help/information about PSU's

I'm going to get a new PSU when I upgrade this winter because the one I have right now is a good 5 years old now. Just want to get a new one for stability and reliability sake I guess.

I'll probably get a motherboard that's going to have two CPU power connectors and I would like to populate those with custom cables. So I have been on a quest to find a PSU that can meet that requirement. Now I stumbled across the Cooler Master V850 Gold and it says 8P PCIE/CPU above 5 8 pin connectors. Can I assume that these connectors can be used interchangeably as long as I use the correct cables?

 

The Corsair RM850i says something similair. 6+2 PCI-E & 4+4 CPU inbetween 5 8 pin connectors. This gives me the impression that as long as you use the right cables, you can have two connectors populated for the cpu and two for the gpu if needed.

Unless you're going for Threadripper or Skylake-X, the extra 8pin is all for show. If you want to look good you could just have the custom cable hanging off the motherboard's connector without being plugged into anything

Yes that's how it works

what cpu are you getting? you probably won't need that second 8 pin

Probably one of the upcoming Intel HEDT parts. And although I know I probably won't need it, I will just populate it for the aesthetics.

Yes the plan is getting a Cascade Lake-X (or Skylake-X idk what the naming is really).

Right, that's what I was hoping to hear!

yeah you'll need that to compensate for 14nm+++++++'s efficiency with high core count like that

That's what I assumed yeah. I watched some of Buildzoid's X570 motherboard teardowns and he always spoke about one 8 pin being equal to about 384W of power. And when I overclock those Cascalde Lake-X parts, I'll probably need the second.

I'm not sure you even need it then.  The FX 9000 series used more power than thread ripper does.  Those boards didn't even have the extra plug.

That's why you have to use 16AWG wire cables for those boards. These days most PSUs use 18AWG, which is thinner, has higher resistance and hence cant push as much power
