This could help someone else on the list. 3ware has Linux tools to monitor the drives or you. And their 9000 series cards are very fast in a RAID configuration. I actually use RAID5 with 1 hot-spare drive. Their older cards were kind of slow. I have a few laying around here as well. No I do not believe that Linux is aware of the power supplies. They do however beep when one is not plugged in. And I have seen a card for windows that you can plug this into and notify you. But not sure of a Linux version. The 3ware and Areca card's are very fast and reliable. SATA is the future and expect it to replace SCSI in the next year or so when SATA-3 comes out at 600MB/s bus and they start coming out with full 10k and 15k drives.
