Tower ECT1250, power for PCIe x1 USB 3.0 expansion card

Has anyone installed a PCIe x1 USB 3.0 expansion card in a Tower1250? I'm trying to do that (PCIe x16 slot already occupied) but haven't yet identified where inside to source the 5v power feed. Tech Support says to find an unused PSU SATA/Molex connector to plug into but I've not been able to find one in this model. Might a solution be to use a splitter/Y lead on the HDD SATA supply - or any other ideas?

Use a SATA power splitter on your hard drive’s power cable to feed the card — it’s safe and works fine.

@smidude​ , @TrevorMc ,

Correct.

You can split-it if needed, but there should be some spare SATA-Power-Cables hanging down by the lower 2.5in drive-bays.
