Topfeel’s W1 squeezes desktop Ryzen processors and a proper graphics card into a case just 5 liters in size. The footprint is only 125 × 198 × 198 mm, yet the hardware inside looks closer to a small gaming tower than a typical mini PC.
The board carries a standard AM5 socket, so it can run full desktop chips instead of mobile parts. That includes Ryzen 7 X3D models aimed at gaming as well as 16-core Ryzen 9 CPUs for heavier work. This alone sets it apart from most compact systems, which usually rely on laptop silicon.
There is also room for a dedicated GPU inside the case, supporting cards from recent launches such as Colorful iGame GeForce RTX 50 Ultra series. The W1 supports full-height, dual-slot PCIe cards up to 188 mm long, which means compact single-fan GPUs can fit without needing an external dock. In this size class, that is still uncommon, since many small PCs stick with integrated graphics.
Cooling relies on a downdraft CPU cooler with six heat pipes, paired with a 120 mm fan and another fan at the top to move hot air out. Packing desktop hardware into a 5L enclosure puts pressure on airflow, so this layout is built to push heat upward and out as quickly as possible.
Memory comes with two DDR5 UDIMM slots, so standard desktop RAM can be installed, following trends in recent DDR5 developments such as HUDIMM DDR5 memory. For storage, there are two M.2 slots, with one supporting PCIe Gen5 and the other PCIe Gen4. The design also allows two extra 2.5-inch drives when a half-height card is installed, giving more flexibility than most mini PCs.
Ports are generous for a compact build. The W1 includes DisplayPort and HDMI, several USB 3.2 Type-A ports, a USB-C port with 10Gbps bandwidth, dual 2.5Gb Ethernet, and an OCuLink port for high-speed expansion.
Power comes through an external DC input, which keeps the power supply outside the case. This helps free up space inside and keeps internal temperatures more manageable.
Compared with mini PCs from GMKtec, Geekom, or Minisforum, which focus on low power and compact size, the W1 leans toward raw performance, moving closer to systems such as Minisforum N5 Max NAS. It brings desktop CPU power and a real GPU into a much smaller footprint than a standard tower.
Topfeel has not shared pricing yet. The W1 is currently listed in China, and there is no word on a wider release.
