I am using a Corsair CS 550M modular power supply. Two 6-pin sockets are labeled Peripheral/Sata, one 6-pin socket is labeled 6+2 PCI-E, and one 8-pin socket is labeled 4+4 CPU. The spacing between the optical drive and HD will not allow one cable to reach both devices, so I will have to run two separate cables.
This would be fine, except I also have to run power to a molex connector for the fan controller in my ARC Mini R2 case. If I use the two Peripheral/Sata sockets to power the optical drive and HD, would I be able to use the 6+2 PCI-E 6-pin socket to power the fan controller?

If not, I will have to relocate the HD closer to the optical drive, so only one cable is required, instead of two.

Comments and/or suggestions will be appreciated.

Hi

If You have a voltmeter to measure with You will find that all the required voltages are not on the PCI-E socket.

Those are to supply power to Video Cards only. I suggest getting a extension cable for the hard drive or relocating it. When I was selling them the extension cables were not expensive.

 

Good Luck

Roger

Thanks, Roger. I think the best solution is to get the extension cable, as you recommended. I really don't want to relocate the HD, since it would impede airflow.

Hi Rob

Air flow is important.
