Topfeel just made external graphics upgrades a lot more attainable with its new G1 and G1 Pro eGPU docks in China. Starting at around $84, these docks lean on OCuLink connectivity to minimize the performance loss that often plagues USB4- and Thunderbolt-based eGPU setups, making them especially attractive for mini PCs and compact desktops that need serious GPU horsepower.
The lineup splits into two designs to fit different builds. The G1 is an open-frame dock built for maximum compatibility, accommodating virtually any full-size desktop graphics card. Its open layout also leaves room for a standard ATX power supply if you want, though Topfeel recommends using a smaller SFX unit for a cleaner, more compact footprint.
The G1 Pro takes the enclosed route for a more finished, living room–friendly look. Because of its tighter chassis, it’s designed specifically for SFX power supplies. Opt for the version bundled with a 600 W SFX PSU, and the dock can power both the installed GPU and a connected mini PC at the same time. Power delivery to the host device tops out at 140 W, which is enough for many compact systems that support high-wattage input.
Both docks connect via OCuLink, a direct PCIe-based link prized by enthusiasts for reducing bandwidth overhead and latency. In practice, that often translates into closer-to-native GPU performance versus many USB4 or Thunderbolt eGPU arrangements, which can bottleneck powerful desktop cards.
Storage and cooling haven’t been overlooked. Each model includes bays for two 2.5-inch SATA drives, letting you expand your game library or scratch disk space right on the dock. The G1 Pro’s enclosure can also take two 120 mm fans to keep airflow strong when you’re pushing heavy workloads or high-refresh gaming.
Prices are straightforward and appealing. In China, the G1 starts at CNY 599 (about $84), while the G1 Pro comes in at CNY 799 (about $112). Both can be bundled with a 600 W SFX power supply for a ready-to-go experience. A wider international release hasn’t been announced yet, though the brand’s hardware often shows up later on global marketplaces.
Key details at a glance:
– Interface: OCuLink for low-overhead, high-throughput GPU connectivity
– Models: G1 open-frame; G1 Pro enclosed
– GPU fitment: G1 open design supports virtually any desktop GPU
– Power supply support: G1 supports ATX or SFX (SFX recommended); G1 Pro supports SFX only
– Optional bundle: 600 W SFX PSU capable of powering both GPU and host device
– Power delivery: Up to 140 W to a connected mini PC (model-dependent)
– Storage expansion: Two 2.5-inch SATA drive bays on both docks
– Cooling: G1 Pro supports two 120 mm fans for added airflow
– Pricing in China: G1 at CNY 599 (~$84); G1 Pro at CNY 799 (~$112)
– Availability: Launching in China first; broader availability to be determined
If you’re building a compact gaming rig or supercharging a mini PC, the G1’s open approach maximizes flexibility and GPU choice, while the G1 Pro offers a tidier, quieter setup with smart power delivery options. Either way, OCuLink connectivity and the aggressive pricing make these docks standout contenders for anyone eyeing an external GPU upgrade.
