Mark, ghm...
I didn't think about that "catch", a PC power supply without any molex
cables. But, it makes sense if you have only a few drives, and they
are all SATA, and there are no CD/DVD-drives (and floppy-drives! ;-) )
And yes, you need the power for USB 3.0 that is not available from PCIe:
USB 3.0 calls for 5 V, 900 mA (4.5W).
This is not always needed in full if the HDD has its own
power-supply, but it's a must if those are "mobile", USB-powered HDDs.
I don't remember PCIe specs and why the power cannot be drawn from it,
maybe it is the voltage (5V) that is not available without a transformer
from PCI-e x1.
Good luck!

Thanks, Igor. I looked at your recommendation but it has a molex power
socket and I only have sata power plugs free in the case - I don't even
see any molex cables in there at all. I picked the first card because of
the sata power port, Inateck's good reputation, and also because it
included a sata power cord extension (which I found was not necessary.)
After that I just looked for NEC chipset and sata power socket, and
eventually also for ports in the needed orientation - those three factors
combined really limit available choices Maybe I'll try the transcend card
and get a sata to molex adapter (I was trying to keep things simple but
obviously have not been successful on that front.)
