Corsair One i300

The Corsair One i300 features high-end Intel Core i9 processors and NVIDIA GeForce RTX 30-series graphics cards in its compact 12-liter chassis. Configurations have included the Intel Core i9-12900K paired with GPUs up to the RTX 3080 or RTX 3090.

The Corsair One i300 packs its components into a compact 12-liter chassis, dramatically smaller than a typical mid-tower desktop. This slim tower design makes it one of the most space-efficient high-performance gaming PCs on the market.

The Corsair One i300 uses a proprietary dual-chamber liquid-cooling design that separates the CPU and GPU into different thermal zones, each with its own radiator and pump. Both the processor and graphics card are liquid-cooled, allowing the slim chassis to handle high-wattage components.

Upgrading the CPU or GPU in the Corsair One i300 is very difficult because of the custom liquid-cooling setup and tightly packed internal layout. RAM and NVMe storage upgrades are more feasible, but major component swaps generally require significant disassembly and compatible cooling hardware.
