Which is probably for the best - I don't know how these newer cards behave, but a commonality of all the older RAID/HBA cards seems to be "no power management allowed". Maybe they improved that area, because it's pretty unreasonable for an idle RAID card to burn double digit Watts if you ask me...
The 9405W cards I most recently tested seem to consume about 7W steady state (which is more than the Pi that was driving it!), so yeah... they're still not quite as efficient as running a smaller SATA card if you just need a few drives. But if you want SAS or Tri-mode (NVMe/SAS/SATA) and have an HBA or RAID card, this is a decent enough way to do it!
