Simple doubt about PSU 8 pin and 4 pin connector, need some help!!

[wsarahan]

Hi guys how are you?

I just bought a new CPU and a new Motherboard in a store and the store mounted it for me with my other pieces

But now i have a question, take a look at the picture:

The guy of course used the 24 pin connector and as you can see this MB has an 8 pin and one more 4 pin connector

Ho here is the question, he only used the 8 pin connector(red arrow), the 4 pin one is not plugged (blue arrow) with the PSU cable is it correct or should i plug both? If the answer is only the 8 pin why the MB have both?

I`m using here a 4770k @4.5 with a H110 2 GTX 780 in SLI and the PSU is a Coolermaster SilentPro Gold 1200W

Thanks

I believe the additional 4 pin will allow you to output your cpu at more then 140 watts.

which, i believe, is standard for all 8 pins

you don't need both plugged in: the 4 pin connector is actually duplicated on pins 3, 4, and 7, 8 of the 8 pin connector. gigabyte added both because it makes overclockers feel better about themselves. 8 pin connector and 8+4 is actually the EPS12V standard (a dual processor workstation standard). ATX12V only specifies the 4 pin connector.

Thanks guys


But my PSU have 2 2x4 pin connector cables so the pin at the board had the 2x4 one and now i only need to use the one part of the other 2x4 pin of the PSU to connect the over energy slot at the board right? Can i use any part of the 2x4 to this connection if i want?

Thanks

Thanks guys just connected here

Whre can i let the other half of the pin? Is there a problem if i let in the top of the case, i mean is there a problem if the pin touch the case? Should i use some isolated tape in the other half?

Thanks

I just used my two 2x4s to fill the 8.
