Do you have to plugin the entire 8 pin CPU connector on the motherboard?

The title might not make much sense, but I have an AMD X4 860k, and the motherboard I am currently using only has a 4 pin CPU connector. I plan on getting a motherboard that will have an 8 pin connector, so will you always have to use whatever connection is on the motherboard? I really don't know how to word this. It is a CPU power connection of course, but if it only needs a 4 pin connector on one motherboard, why would another need an 8 pin connector? That's what I'm really trying to ask.

It will depend on the motherboard as to if it has a 4 pin or 8 pin CPU connector. Lower end boards and boards designed for office work don't necessarily need to feed extra power to the CPU while higher end enthusiast boards designed for overclocking and high end systems will have the extra power available.

An 860K will perform identically in a board that has a 4 pin connector vs a board with an 8 pin connector though. Same is true of any CPU. All you might gain is a little overclock headroom. And yes you will need to plug in the 8 pin connector.

Well it's the exact same CPU.

In general it should work fine. Same as only having a 20-pin connector on the power supply when the motherboard wants for a 24-pin plug.
But recommended is to plug in what is asked for.
The extra lines are not only to provide more power but also to balance out the load on the connector.
