For PC enthusiasts and mini-PC users, the external GPU (eGPU) dock has long been a gateway to desktop-level graphics performance on the go. However, the market is often dominated by a few big names with premium price tags. Enter Topfeel, a brand that's challenging the status quo with the launch of its new G1 and G1 Pro eGPU docks in China, offering a compelling mix of flexibility, expansion, and a very accessible price point.
The two new docks cater to different user preferences, but both share a core focus on minimizing performance loss and maximizing functionality beyond just graphics.
The Open-Air Contender: Topfeel G1
The standard Topfeel G1 model makes a bold statement with its open-frame design. This isn't just an aesthetic choice; it's a functional one. The open nature means it has virtually no restrictions on the size of the desktop GPU you can install. Whether you're looking to slot in a triple-slot behemoth or a more modest card, the G1 is ready to accommodate it.
This flexibility extends to the power supply as well. The dock can house a standard ATX PSU, which many users may already have on hand. However, for those aiming for a cleaner and more compact setup, Topfeel recommends using an SFX power supply. You can check out the design and get a closer look at the G1 on its official JD.com product page.
The Streamlined Solution: Topfeel G1 Pro
If an open chassis isn't your style, the Topfeel G1 Pro offers a fully enclosed design. This provides a more finished look and better physical protection for your components. The trade-off is a more defined limitation on the power supply, as the G1 Pro is designed specifically for SFX PSUs.
The Pro model has a significant trick up its sleeve, though. Topfeel notes that its optional bundled PSU can simultaneously power both the high-end graphics card inside the dock and the connected mini-PC. This is a huge convenience, eliminating the need for a separate power brick for your small form-factor computer. For a compatible device, look no further than something like the GMK EVO-X1 mini PC (currently $819.99 on Amazon with 32GB RAM and a crucial OCuLink port). It's worth noting that the power delivery to the mini-PC tops out at a healthy 140W, which is ample for most devices.
The Secret Sauce: OCuLink and Storage Expansion
Where both models truly shine is in their connectivity and unexpected expansion features.
- Superior OCuLink Connection: Instead of relying on the more common USB4 or Thunderbolt standards, both Topfeel docks utilize an OCuLink connection. For the uninitiated, OCuLink is a PCIe-based interface known for offering significantly lower GPU performance degradation compared to USB4 and even the new Thunderbolt 5. This means you get more bang for your buck, with more of your GPU's raw power making it to your screen.
- Built-in Storage Expansion: In a clever twist, Topfeel has integrated support for two 2.5-inch SATA drives into both docks. This transforms the eGPU from a single-purpose device into a holistic docking station, allowing you to add terabytes of extra storage for your game library or projects without cluttering your desk or mini-PC.
- Enhanced Cooling on the G1 Pro: The enclosed G1 Pro doesn't skimp on cooling, either. It features the ability to mount two 120mm fans, ensuring that both your GPU and those new storage drives stay cool under pressure.
Pricing, Availability, and Global Hopes
The most startling part of this launch might be the price. The open-frame Topfeel G1 starts at an incredibly accessible CNY 599 (approximately $84), while the enclosed G1 Pro begins at CNY 799 (around $112). Both can be bundled with a 600W SFX power supply for a complete out-of-the-box solution.
As of now, the launch is confined to the Chinese market. However, given that most of Topfeel's products eventually find their way to global platforms like AliExpress, there's a strong likelihood that international users will get a chance to experience this powerful and affordable eGPU solution soon. For mini-PC users craving more graphical muscle and storage, the wait for a global release will certainly be worthwhile.
