External GPU solutions have evolved significantly in recent years, moving beyond basic connectivity to address the power demands of modern graphics cards. Sparkle’s latest additions at Computex 2026 demonstrate this progression, offering specialized enclosures that push the boundaries of what Thunderbolt 5 can deliver without compromising on compatibility or performance.
The Sparkle eGPU Studio-G Ultra 850 is designed for high-end graphics cards, including the RTX 5090. It supports up to a 33 cm long GPU and includes an 850 W power supply with a 12V-2x6 connection, capable of delivering 600 W continuously. This setup ensures stable operation even for the most demanding workloads, where power delivery can be a limiting factor. The enclosure leverages Thunderbolt 5’s asymmetric mode, providing 120 Gbps receive and 40 Gbps transmit bandwidth, or symmetric 80 Gbps in both directions if needed.
For users with more moderate requirements, the Sparkle eGPU Creator Station offers a pre-built solution centered around an NVIDIA GeForce RTX 3060 12 GB. Unlike the Studio-G Ultra, this enclosure includes additional downstream I/O, such as two 10 Gbps USB 3.2 Gen 2 Type-A ports, two Thunderbolt 5 ports (one with DisplayPort passthrough), and a 1 GbE wired LAN connection. The inclusion of multiple full-sized DisplayPorts ensures compatibility with multi-monitor setups, while the color options—silver, white, red, blue, and gold—provide flexibility for aesthetic preferences.
These new enclosures address a critical gap in the market: the need for high-performance external GPU solutions that balance power delivery with connectivity. The RTX 5090, for example, demands significant power, often pushing the limits of traditional enclosures. The Studio-G Ultra 850’s 600 W continuous delivery capability directly tackles this issue, ensuring stability without requiring complex power management setups. Meanwhile, the Creator Station simplifies workflows for users who need both GPU performance and additional I/O options in a single package.
The shift toward Thunderbolt 5 as the standard interface for external GPUs reflects broader trends in connectivity, where bandwidth and power delivery are increasingly intertwined. Previous generations of eGPU solutions often relied on PCIe or other interfaces that limited scalability. Thunderbolt 5 changes this dynamic by providing the necessary throughput while also supporting high-power devices through its 12V-2x6 connector standard. This is particularly important for professional workloads, such as 3D rendering or AI development, where both performance and stability are non-negotiable.
For PC builders and system administrators, these enclosures represent a practical solution to the challenges of integrating high-end GPUs into existing setups. The ability to add significant compute power without modifying the host system’s internal components is valuable in environments where flexibility and scalability are priorities. However, the reliance on Thunderbolt 5 means that users must ensure their host systems support this interface, which could be a limiting factor for some configurations.
Looking ahead, the introduction of these enclosures signals a maturing market for external GPUs. The focus on both high-end and mid-range options suggests that Sparkle is targeting a range of users, from professionals requiring maximum performance to enthusiasts looking for expandable solutions. As Thunderbolt 5 becomes more widespread, the potential for even higher-performance external GPU setups will grow, but for now, these enclosures set a strong benchmark for what is achievable today.
