The Corsair One i300 ($3,799.99 to start; $4,999.99 as tested) charges in The opposite way, putting an Intel Core i9-12900K and an Nvidia GeForce RTX 3080 Ti in a 12-liter chassis that is comparable to the size of a console. Although the design is somewhat approachable and features liquid cooling for both the CPU and GPU, it can’t be upgraded as easily as enthusiast mid-towers.

Corsair One i300 review: Design

Since its release in 2017, the Corsair One has been our go-to tiny gaming desktop. With an Intel Core i9-12900K processor, cutting-edge DDR5 memory, and GPUs up to the Nvidia GeForce RTX 3080 Ti for unmatched power in such a space-saving design, this year’s One i300 is the most stunning revision yet. It operates almost silently, is totally liquid-cooled, and has a stylish appearance like prior Corsair One models. The only thing we can really bemoan is the price, which starts at a startling $3,999 and soars to $4,999 in testing. Because of this, the Corsair One a200, which is more inexpensive (though still expensive), keeps our title for a high-end compact gaming tower and is powered by an AMD Ryzen 9 CPU in our test model. The One i300 is the “one” to buy if your demand for speed is insatiable, nevertheless.

Corsair One i300 review: Graphics and Gaming Tests

Both include three DisplayPort 1.4a outputs and one HDMI 2.1 output, but oddly, there is no means to connect to the CPU’s on-board graphics. Although you probably wouldn’t want to utilize the Intel UHD Graphics 770 for gaming if your computer already has Nvidia’s finest graphics card, the extra ports can be useful when debugging, thus this absence is perplexing. This is a minor flaw in an otherwise strong I/O, though. The only variations between the least costly $3,999 USD version and the most expensive $4,999 USD version of the Corsair One i300 are the quantity of gaming RAM and graphics card models inside of them. A Z690 Mini ITX motherboard with an Intel Core i9-12900K processor, 2TB of PCIe Gen 4 NVMe storage, and a Corsair 750W 80 Plus Platinum PSU are shared by all the different configurations. 32GB of 4,800MHz dual-channel Corsair DDR5 memory and a liquid-cooled GeForce RTX 3080 10GB graphics card are included in the minimum specifications. You can buy this CPU from its official website.

Corsair One i300 review: Gaming Performance

Performance-wise, the Corsair One i300 is simply stunning for gaming. It can support extremely high frame rates on 1080p or QHD monitors; on 4K TVs, you’re still unlikely to fall below 60 frames per second.

Since it has a little more power, this is not shocking, but it is excellent news for gamers who want to set their games to their highest possible settings and have 4K displays. Even the PS5 and Xbox Series X can’t regularly match the frame rates of 4K games, which never went below 60 fps.
