[SOLVED] USB expansion cards: SATA vs non-SATA

[Linerax]

What are the differences between a USB expansion card that is solely connected to the PCIe slot and a card that also requires a SATA connection? Is the expansion card which needs SATA able to draw more electrical current from the motherboard? Or is SATA connection an alternative method for the expansion card to function?

SATA connection required: https://www.amazon.com/gp/product/B00FPIMICA

Power delivery. Ones with SATA/Molex connector can deliver more power to USB devices.
