My PSU came with 2 cpu 8 pin cables?

Go to solution Solved by mariushm,

It's perfectly normal for a power supply to come with 2 CPU 8 pin

Sometimes one of the cables can be split in 2  CPU 4 pin connectors, maybe that's why it says in smaller letters on one cable.

 

This makes it possible to power a motherboard that has only one 4 pin CPU connector, or motherboards with one 8 pin and one 4 pin connector.

 

Only ONE 8 pin is needed, if your motherboard has more than one 8 pin.  Anything else is optional, and only needed if you have very power hungry processors (think 12 or 16 core processors).

If you don't like the extra cables, then your computer will be perfectly fine with just the 8 pin connector populated.

 

A single 8 pin connector can give the processor over 300 watts. The 5600x will not consume more than 100-125 watts.  Extra power connectors are not needed when the first cable is barely used to half of its capabilities.

So do I need to use both cables or just 1?

 

I'm also a bit comfused because the text written on it diffrent for the other one

One cable has 2 times small cpu on it 

The second cable has writting CPU big on it?

A lot of motherboards nowadays have multiple CPU power connectors. Often an 8 pin and 4 pin.

Usually the 8 pin is only needed.

 

One cable probably has CPU written on it twice, because it can split into two 4 pin cables.

So should I connect both or just 1 the 8 pin?

What motherboard and CPU are you using?

You'd only need the 8 pin cable.

need, yea, but since you have both why not use both?

I think it it is useless to use both if it not even take half the cpu power a cable can handle. because the guy a few post back said it only takes about 125 watt and a cable can transfer 300 watt I just saw.

yeah. Just, for me, I don't like how empty power headers look. which is the whole reason i suggested using both.

Well go right ahead and suggest that to OP and not ask me.

Why use a cable you don't need? It will only get in the way.

 

Of course the counter-argument would be that having it installed ensures if you're going to install a more power hungry CPU in the future you don't have to run another cable I suppose.
