Quick question on PCIe-based SATA expansion cards. I need to add some internal SATA ports because my hack's Asus Z490-P mobo has only four. I've done a lot of searching regarding PCIe expansion cards, as well as reviewing the official PCIe specifications, but they mostly talk (brag) about throughput and performance.
I'm more concerned with power issues. As I understand, the PCIe slot draws lower power than a SATA II or SATA III hard drive requires. Throughput aside, I need to know if a PCIe slot's power can in actuality support the power requirements of 2-4 additional 3.5" hard drives. Maybe I just haven't searched the right place to get an easy answer, so I'm trying here in the hopes that I can find out yea/nay.
If it makes any difference, the drives I want to install are mainly for storage. They wouldn't be accessed continuously or simultaneously.
TIA
