Do I need to connect an additional power cable from my power supply to a StarTech.com USB expansion card?
It depends; a StarTech.com USB expansion card can be powered by the PCI or PCIe slot, but an additional power cable (such as SATA or Molex) is required if connected USB devices exceed the available slot power. Explanation: A StarTech.com USB expansion card draws power from the motherboard through the PCI or PCI Express slot, which is sufficient for many standard USB devices. However, total available power is limited by the slot. Slot-powered operation: Low-power devices such as USB keyboards, mice, and flash drives typically work without additional power. Auxiliary power requirement: High-power devices, such as external hard drives without their own power supply, may exceed slot power limits and require a direct connection to the system power supply (for example, SATA or Molex). Power-related failure symptoms: Insufficient power may cause devices to disconnect, fail to initialize, or not function simultaneously. Troubleshooting requirement: If any of these issues occur, connecting an auxiliary power cable to the USB expansion card is required for stable operation. A StarTech.com USB expansion card will not reliably power high-demand USB devices without sufficient total power from either the PCI/PCIe slot or an additional power connection.
