Product Description
The PURPLELEC TB1015A40 is an 80Gbps eGPU dock built around a Thunderbolt 5 host connection. Designed as an external graphics card dock for laptops and compact workstations, it allows compatible systems to use a desktop graphics card through a high-speed Type-C connection.
With a full-length PCIe graphics card slot and space for an independent power supply, TB1015A40 provides a flexible platform for video production, 3D rendering, photography, engineering and other graphics-intensive workflows.
Add a Desktop Graphics Card to Your Laptop
TB1015A40 supports compatible desktop graphics cards from major NVIDIA and AMD product families. Its full-length PCIe slot accommodates graphics cards up to 400 mm, making it suitable for a wide range of professional and high-performance GPU configurations.
Actual graphics performance depends on the selected GPU, host computer, operating system, driver, application and Thunderbolt connection.
Thunderbolt 5 Graphics Card Dock Connectivity
As a Thunderbolt 5 graphics card dock, TB1015A40 provides host connection bandwidth up to 80Gbps for external graphics and peripheral expansion.
Additional Thunderbolt and USB-A connectivity allows compatible storage devices, displays and accessories to be connected alongside the external GPU.
Backward compatibility with Thunderbolt 3, Thunderbolt 4 and USB4 depends on the host implementation. Available bandwidth and functionality will be limited by the host computer and connected devices.
Flexible GPU and Power Supply Installation
The external GPU enclosure provides space for a full-length desktop graphics card and a compatible 2U server power supply, allowing users to select an appropriate power configuration for their GPU.
The accessible installation layout, securing mechanism and auxiliary pull tab make it easier to install and maintain the graphics card and power supply.
The graphics card and power supply are sold separately.
High-Resolution Creative Workflows
When paired with a compatible graphics card, host computer, cable and display configuration, TB1015A40 can support display workflows up to dual 8K at 60Hz.
Available resolution and display quantity depend on the graphics card outputs, GPU driver, host capability, connected displays and application requirements.
TB1015A40 is suitable for:
• Video editing and post-production
• 3D rendering and design
• Photography and studio workflows
• Engineering and visualization
• Multi-display workstations
• GPU-accelerated professional applications
Compatibility Notice
A USB-C or USB4 connector alone does not guarantee external GPU support. The host computer must support the required Thunderbolt or PCIe tunneling functionality, and an appropriate graphics driver must be available for the selected GPU.
For macOS, eGPU support is limited to compatible Intel-based Macs with Thunderbolt 3 and supported graphics cards. Apple silicon Macs do not support eGPU operation.
Confirm the host computer, operating system, graphics card, power supply and application compatibility before deployment.

Q1: Does the TB1015A40 include a graphics card or power supply?
No. The package includes the eGPU dock and connection cable. The desktop graphics card and 2U server power supply are sold separately.
Q2: What type of computer is required?
Thunderbolt 5 is recommended for full bandwidth. Thunderbolt 3, Thunderbolt 4 and USB4 compatibility depends on whether the host computer supports PCIe tunneling and external GPU operation. A USB-C connector alone does not guarantee compatibility.
Q3: Which graphics cards are supported?
TB1015A40 supports compatible NVIDIA and AMD desktop graphics cards up to 400 mm in length. Final compatibility depends on the operating system, GPU driver, physical size and power requirements.
Q4: What power supply should I use?
The integrated power bay is designed for a compatible 2U server power supply. Select a power supply with sufficient output for the installed graphics card and confirm that its dimensions fit the enclosure.
Q5: What is the maximum connection speed?
The Thunderbolt 5 host connection supports bandwidth up to 80Gbps. Actual graphics and data performance depends on the host computer, graphics card, driver, cable and application.
Q6: Does it support dual 8K displays?
It can support display workflows up to dual 8K at 60Hz when used with a compatible graphics card, host computer, cable and displays. Available resolution and display quantity depend on the complete system configuration.
Q7: Does it work with MacBooks?
macOS eGPU support is limited to compatible Intel-based Macs with Thunderbolt 3 and supported graphics cards. Apple silicon Macs do not support external GPU operation.
Q8: Can I replace the graphics card while the dock is powered on?
For safety, turn off the dock and disconnect its power before installing or replacing the graphics card or power supply. Do not remove components during active data transfer.
