HDDS that can run on 1 PSU cable.


Recommended Posts

Hi All,

 

I am very new to unRAID and just recently decided to put a homelab server / media server / NAS together using unRAID. I just got a RSV-L4412 case. The hot-swap bays of the case take 2 molex connectors each supporting 4 HDDs, in total there are 6 molex connectors to the total of 12 HDDs.

 

I got a new PSU for this project, the Seasonic GX-650 PSU. I was thinking of using 1 SATA power cable, and using SATA to 2x Molex splitters to go to all molex power inputs for the HDDs.

 

I was trying to find specs of the wire ti see if this is OK, but can't seem to find it online.

 

Any thoughts if this is fine?

 

Thanks!

12 drives going through a single cable is a bit much.  You've got a total of 5 molex connectors on that PSU, spread out between 2 cables.  Then use a SATA to Molex for the remainder from another cable.

Thanks! Will do.

I have 12 drives powered by a backplane which uses 3 molex as input. I wouldn't feel comfortable running more than 4 drives off one header. Had a friend running 6 drives off one header in a non-unraid setup, and he kept getting drives dropping out of his raid array. Turns out that putting 3 on a separate header solved the issue.
