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 would say the 4 pin socket is used when lower CPU's are installed (ones with a lower TDP or dual core) :)
 
Gigabyte included both a 4-pin and 8-pin EPS connector to make sure you have enough power available and that providing it doesn't create one huge, hot path down the board's surface. You can use one or the other, or both. I say BOTH :p.

Taken from a review website(use at your own risk)
Have you read the manual?
just had a look at the manual does not say if you should use both????

The blue four pin is sufficient according to the ATX specifictions. Follow the recommendations made by the manufacturer in the motherboard manual. In the past I have used both sockets without ill effect and used one or the other.
 
Thanks guys

I was looking here at my MB box and it says that i has one 20 pin + 4 pin and two 4+4 pin, so i just need to connect any half of this other 4+4 pin right? Any 4 half pin or should be the left side ir right side of the cable?
 
Very nice board, it has a real solid quality feel to it. A few little niggles due to the layout. Bit tighter spaced for sli than my previous P8 Z77 V Pro, lost the use of my xonar DX as the cpu cooler, (k2 mount doom) covers the top x1 pcie slot. But ill hold onto the card incase i ever change coolers. The bios options are mind boggling but ill have a good read of a few guides before starting any overclocking. Iirc your watercooling your system, good luck with the build and look forward to seeing the finished article.:)
 
Glad you asked this. I have the Z87X-OC and couldn't work it out either as the manual didn't say one way or another.
Can't you use your xonar in the bottom slot?

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

By placing the card in the bottom red slot this reduces the speed of the gpu's in sli. There is a slot available between the cards, but it would block what little airflow the top card has. The only other option is a slimmer air cooler, or something like a corsair closed loop unit. The latter i wouldnt touch with a barge pole tbh.
 
Is that mother board specific then? I read something to the contrary regarding the lanes.
I am running a single GPU in a 16x slot and have my Xonar in the bottom slot, I also have options to disable unused lanes so will be interesting to see if it effects it.
GPU-Z would report the pcie speed right?
 
Ive read it on another forum, will see if i can find the article. As im running non reference gtx 670's in sli. I need the best spacing possible. My previous P8Z77 V Pro board was ideal as it had a good gap between the primary pcie gpu slots, and i was able to use the x1 slot above the top gpu. Pic of the old setup below.

 
According to 8 pack who runs some seriously high cpu and gpu clocks including sli/xfire, youll be fine with just the standard 8 pin cpu plug, and no need for the extra gpu power connector either. I take it your power supply is a newer model that features an extra 4 pin cpu plug. If so it will be fine just tucked away. As the metal part of the connector is insulated by plastic, theres not much chance of it shorting on the case. Ive left loads of connectors like this on my builds over the years.
 
My psu is new and good one, no need to replace and no money to do it now :) So i don`t need to worry about letting the other half of the 8 pin touching the case? Here`s a picute how it is

As you can see it`s plugged correctly right?

As you can see in the top left is the another half of the cable, no problem right?

Thanks
