The docking station has a built-in cooling fan and a dual air duct design to dissipate heat for the docking station and the graphics card backplane.Provide dual 8Pin and 16Pin (12VHPWR) graphics card power cables to provide 280W continuous and stable power supply for the graphics card. (This data is measured using a 330W GaN power supply. To system stability, it is recommended that the maximum power consumption of the graphics card used is within 290W.)The docking station Equipped with a chassis, the maximum supported size of the graphics card supported by this chassis is 268mm long, 133mm high, and 52m wide. If the graphics card length exceeds 262mm, it may be necessary to remove the front panel of the chassis for installation.Parameters:Interface:for Thunderbolt3/4 USB4 *2Chipset: JHL7440 or JHL7540 (Note: The main control chip JHL7440 or JHL7540 is shipped randomly, but the chip performance parameters are the same and not affect use.)Daisy chain: SupportDaisy chain: SupportSupported power supply: Support GaN power supply/laptop power supplyApplicable scenarios: portable/desktop usePD charging: Max 20V4.25A@85WPower interface: for Square PortGraphics card power consumption: 330W (20V)Other functions: Synchronous and stop (synchronous and stop means that the docking station, graphics card and power supply and shut down with the computer.)Special note:1. Some devices with Thunderbolt3 interfaces actually run at 16Gbps due to computer chipset limitations.2. Software or games have different requirements for PCI-E bandwidth, and the performance be different. Mid and low-end graphics cards have better performance because they do not require high PCI-E bandwidth. Connecting a monitor to the output of the expansion graphics card achieve better performance.Color: As ShownMaterial: Metal Package Contents:1 * docking station with Chassis1 * for 4 data cable1 * 16PIN graphics card power cable1 * Dual 8PIN graphics card power cable
