Trying to figure out if this will work. I have this LSI SAS9201-8i raid controller mounted to my motherboard originally to allow for more drives via a mini SAS 8087 to 4 sata connectors. Works flawlessly (mntherboard only has 4 sata which are used). I recently came into quite a few SAS drives. That being said, would I be able to use a mini SAS 8087 to 4 SFF-8482 Connectors with SATA Power connected to the second port on the LSI raid controller and have the SAS drives work?

Yes.

But mind you, a SAS drive has a different method, if any, for spindown....use this plugin:

Another gotcha I ran into after also reading about it here and other places is the SAS 3.3v power pin issue. This could likely affect you with your SAS drives. I also used the SAS SFF 8087 breakout cables with SATA power input cables. If you do that, you can't use regular daisy-chain SATA power cables. Instead of messing around with pin-masking, I recommend you use a Molex to multiple SATA power adapter like this which simply bypasses the 3.3v power pin to the SATA adapters which let my system boot and SAS drives spin-up. Just make sure your power supply has a Molex power output cable free.
