Hi,had a new motherboard (Asus X99-A II) which has an 8 pin CPU connection as well as a 4 pin. The last motherboard I had only had the 8 pin and I have lost the other 4+4 CPU cable that came with the power supply, my question is do I have to connect both 8 and 4 cables or is the 4 pin just for overclocking as i have read on other sites. I dont intend to overclock until i do find a replacement and PC boots into Bios fine just dont know if ill be OK to carry on installing windows. Asus have not been back in touch or any replays on forum Any help would be great,many thanks
Hi there If you do plan to OC in future I would use 8 pin(4+4) connector,this second connector not sure if you are neex to have connected,in my opinion I would say,you don't need that there to have connected Yours PC should be OK and you can start or carry on with installation of Windows I'm using 4+4 pin for powering CPU and don't have any issue,my 5820k is OC to 4.4GHz right now and everything is very stable Hope this helps and good luck there Thanks,Jura
CPU OPT is usually a Fan header. No idea why that sort of socket is being used. In my experience its usually a standard 4-pin fan header connection, like the white one in the far left top in your pic.
I've got the same on my board, it's an optional (OPT) extra power for the CPU if you are going for big CPU OCs, to take some of the load off the other connector / part of the board If you go for an extreme OC without using it, fire can happen so I'm told
Yup same as yours, I wish I would have gotten yours, mine works does same thing but you can keep voltages more stable on yours thus less heat. I've got a 0.056 voltage droop on mine so I have to go up a little more on voltage 1.53 with 4.7 because it droops 1.48 that's the bonus for the extra 4 pin.
If you have LLC in your BIOS, set that higher to combat vDroop, I had to do that to stabilize my chip Spoiler
If you check your mainboard's manual, page 1-26, it does make an extra statement to connect both 8 and 4 pin ATX12V plugs... If it works, good, I'd personally try to grab one of those 4 pin cables or an adapter on the long run. Just my opinion though.
Well I hope it won't tear you down to ruin, but as I said, I personally would have looked for such a cable anyway, just to be sure.
