ArsenalPC Gigabyte C301 GLASS System

The ArsenalPC Gigabyte C301 GLASS is a pre-assembled gaming desktop built around an Intel Core Ultra 7 265KF 20-core processor reaching 5.4GHz. It pairs this CPU with an NVIDIA GeForce RTX 5090 graphics card carrying 32GB GDDR7 memory. The system includes 128GB DDR5 RAM across four slots and a 4TB NVMe SSD. A 1200W power supply and 240mm liquid cooler support the high-performance components inside the glass-panel chassis for enthusiasts seeking immediate 4K gaming capability.

Installation and Common Issues

The desktop arrives fully assembled with Windows 11 Home installed and tested, so no component installation is required. The 240mm liquid cooler is pre-mounted and filled, eliminating the complexity of custom loop setup. Builders should verify that all power cables remain firmly seated after transit, as the high-wattage GPU and CPU draws can loosen connectors. The four memory slots are fully populated, so future RAM upgrades require module replacement rather than simple addition.

Sustained Load Behaviour

Under continuous heavy workloads the 1200W power supply delivers stable current to both the 20-core processor and RTX 5090 without throttling. The 240mm liquid cooler maintains lower CPU temperatures than air alternatives during extended sessions, keeping the 5.4GHz boost clocks attainable. The 4TB NVMe SSD sustains high write speeds without thermal slowdown thanks to direct motherboard mounting. The fully populated 128GB DDR5 configuration runs at rated speed continuously, avoiding the downclocking sometimes seen with mixed-capacity kits.
