ArsenalPC Gigabyte C301 GLASS Ultra 9 285K

This gaming desktop pairs an Intel Core Ultra 9 285K 24-core processor running at 5.7GHz with an NVIDIA GeForce RTX 5080 graphics card. It is built for enthusiasts who want high frame rates at 4K resolution and smooth virtual reality experiences. The system ships with Windows 11 Home installed and includes Wi-Fi and RGB lighting. Buyers needing a workstation certified for specific professional applications should look elsewhere.

128GB DDR5 memory and 4TB NVMe storage

The four memory slots are fully populated with 128GB of DDR5 RAM, giving ample headroom for modern games, streaming and heavy multitasking. The 4TB NVMe SSD provides fast load times and space for a large library. Users who anticipate needing more than 128GB of memory or multiple separate storage volumes will find the current configuration limiting.

240mm liquid cooler and 1000W power supply

A 240mm liquid cooler manages thermals for the 24-core CPU under sustained loads. The 1000W power supply delivers stable power to the RTX 5080 and the rest of the system during peak draw. Acoustic output will vary with fan curves and workload intensity.

Questions about this item

Will the LGA 1851 socket on this Ultra 9 285K system accept my existing cooler mounting kit?

The 240mm liquid cooler included with the PC is pre-installed on the Ultra 9 285K, so no separate mounting hardware is required for the CPU.

How can I confirm the RTX 5080 is running at its full PCI Express x16 speed after I set up the desktop?

Open GPU-Z or the NVIDIA control panel and verify the bus interface reads PCI Express x16; the RTX 5080 16GB GDDR7 will show the active link width there.

Does the 4TB NVMe SSD ship installed, or do I need to buy a drive and fit it myself?

The 4TB NVMe SSD comes already installed in the chassis along with Windows 11 Home, 128GB DDR5 RAM and the 1000W power supply — no extra parts are needed to start.
