Thunderbolt 3 to PCIe USB 3.1 Adapter - 10Gbps - Chassis + 4 Port Card

Questions & Answers

My DisplayPort displays are not working at 60Hz with this adapter. How do I resolve this issue?
To use a Thunderbolt 3 adapter to output to a display at 60Hz, your monitor must support the refresh rate and you need to set the monitor to work at 60Hz. By default, most monitors are set to DP1.1, which will not work with this Thunderbolt 3 device when you use a display at 60Hz. In most cases, you need to set your monitor's DisplayPort settings to DP1.2. To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.2. For more information about changing your monitor settings, refer to the website of the manufacturer of your monitor.

Can I use a Thunderbolt 3, Thunderbolt 4, or Thunderbolt 5 device on a USB-C or USB4 port?
No, a Thunderbolt 3, Thunderbolt 4, or Thunderbolt 5 device requires a Thunderbolt-enabled port and will not work on a USB-C port that does not support Thunderbolt. Explanation: Thunderbolt 3, Thunderbolt 4, and Thunderbolt 5 use the USB-C connector, but they require Thunderbolt protocol support from the host port, cable, and device. Compatibility rules are as follows: A Thunderbolt device (Thunderbolt 3, 4, or 5) only works when connected to a Thunderbolt-enabled USB-C port. A standard USB-C port without Thunderbolt support does not support Thunderbolt devices and will result in no functionality. USB-C devices are compatible with Thunderbolt 3, Thunderbolt 4, and Thunderbolt 5 ports because Thunderbolt includes USB support. USB4 ports may support Thunderbolt 3 devices, but this support is optional and not guaranteed. USB4 does not ensure compatibility with Thunderbolt 4 or Thunderbolt 5 devices. To confirm compatibility, look for the Thunderbolt symbol on the host port, cable, and device. If the Thunderbolt symbol is not present, the connection supports USB-C only and does not support Thunderbolt devices. All components in the connection must support the required Thunderbolt standard to ensure proper operation and full performance.

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.

What DC barrel connector power plug types do StarTech.com products use, and what are their dimensions?
StarTech.com DC barrel connector plug types are defined in the “Plug Type” field of the technical specifications, using a letter code that specifies the connector’s outer diameter (OD) and inner diameter (ID) in millimeters for power adapter compatibility. Explanation: In StarTech.com technical specifications, the “Plug Type” field is a standardized identifier for the exact DC barrel connector size required to power a product. Each plug type is assigned a letter code that corresponds to a specific combination of outer diameter (OD) and inner diameter (ID), measured in millimeters. Common DC barrel plug type dimensions Plug Type OD ID A 2.35 mm 0.7 mm B 4.0 mm 1.7 mm C 4.75 mm 1.7 mm H 3.4 mm 1.3 mm L 5.0 mm 2.5 mm M 5.5 mm 2.1 mm N 5.5 mm 2.5 mm The DC barrel connector plug type must match both the outer diameter and inner diameter exactly. A mismatch between the StarTech.com product requirement and the power adapter connector can prevent proper fit or stable power delivery, which may result in device startup failure or intermittent operation. The plug type defines only the physical connector size. The plug type does not define electrical power requirements such as voltage, current, or polarity. The power adapter used with a StarTech.com product must match the product’s specified electrical requirements. Using an incompatible power adapter can cause device malfunction or permanent damage. This standardized DC barrel connector plug type system enables IT professionals and procurement teams to verify connector dimensions, ensure power adapter compatibility, standardize hardware deployments, and identify the correct replacement power supply for StarTech.com products.
