8 and 4 pin Crosshair V connectors

post #1 of 10
Thread Starter 
So I was looking over my new Crosshair V and I'm a bit confused by the manual's description of the power connectors. There's a 4 pin and an 8 pin, but the 8 pin has a cover over half of the pins. What does each send power to, and do I need all of them plugged in?

I think it has a single 8pin that can work for the 4pin plug on some motherboards. Or it might split into two 4 pins and go together for the motherboards 8 pin.

That's basically the AUX power for the CPU, it helps with overclocking. Yes, plug all 8 pins in, the cover is for if your PSU only has a 4 pin plug.

So the 8 pin is the main connector and the 4 pin just gives the CPU some extra kick? Alrighty, thanks

Yes. Im just using the 8 pin for now with my hex core, since its all i used before. It would not hurt to use all 8+4 pins though. Im guessing the higher end bulldozer chips will prefer this.

kinda not exactly. The 8 pin and the 4 pin are both CPU power connectors, some motherboards have an 8pin or a 4pin(mainly low end and older boards).
You have one or the other, not both. Just wanted to clarify that.

Nope, Crosshair V has both. I have the board 2 feet away from me.

Kind of like how some boards have two 8-pin connectors. They're great for extreme overclocking (LN2, DICE, etc.).
