Asrock z97 Extreme6 4-pin problem (Cannot plug due to PSU in the way)

Diego Hostettler · Mar 3, 2015

Hello

I got me a asrock z97 extreme today. After powering up i got the error that i have to plug in the 4pin. After googling a bit i found out that the asrock boards have additional power sockets for pci. It looks like a old hard drive 4-pin power socket.

So after connecting the 4-pin the board finally is booting properly. Now to the problem!!

The plug can be found on the bottom of the mainboard. If i plug it im not able to fit the PSU in my computer case anymore! My computer case is a normal ATX normed Mid Tower. Thus getting a new midtower with the psu located at the bottom will probably never fit this mainboard due to the plug that is just not fitting between the psu and the board.

So my question is, does the board really need this additional power or can i turn it off in bios? If i can do this would the board still be functional? I never had a Asrock board. Usually i go with Asus and i so far have never heard of a board requiring a separate power socket for the PCIe slots?

Thanks for you help

You don;t need to plug the molex connector for the PCIE if you just using one GPU.
If you refer to your motherboard's manual p28
"Please connect a 4 pin molex power cable to this connector when more than three graphics cards are installed. "

If in doubt with your motherboard, look it up in your manual.
Link to your manual if you don't have it for some reason:

You could always get a molex extension cable (molex is what the connector is called).

If you have a dedicated GPU with its own power and no other addon cards needing power then you likely could go without it.
Is there anything in the manual about it?

i have to use the additional power it seems. i only run 1 msi gt970 graphics card. but as soon as i use the pci_5 slot for my audio card OR wifi card the board won't boot and asks for additional power.

i probably just gonna switch to a asus board. i was using a z87 without any issues with the same pcie cards for a long time. asrock should write in BIG letters that the mainboard only delivers sufficient power to 4 out of the 5 Pcie slots. .or at least put that molex somewhere where it is accessible with a normal case.

Switched to a Asus z97 MAXIMUS VII RANGER. Works perfectly!
