I am building a raid array in a separate enclosure. I will be putting an empty tower case next to an existing tower computer, and this second tower case will only hold hard drives.

There are many solutions for connecting the drives in the second case to the raid card in the first case (SFF-8088 and SFF-8087 cables).

But I prefer not to run power from the first case to the second case. Can I use a power supply in the first tower case and cause it to start the power supply in the second case based on an indication from power in the first tower case's power supply?

Maybe run a 12 volt cable from the first case to the power supply on the second case only for the purpose of initiating the second power supply.

At my new home, I turned them… >>> More
