Intel Core Ultra 9 285K desktop

The ArsenalPC Gigabyte C301 GLASS is a pre-built gaming desktop powered by an Intel Core Ultra 9 285K processor running at 5.7 GHz with 24 cores. It includes 64 GB of DDR5 memory across four slots and a 4 TB NVMe SSD for primary storage. A 240 mm liquid cooler and 1200 W power supply support the components inside the glass-panel chassis. Windows 11 Home is installed and the system ships tested and ready to use.

4K enthusiasts seeking maximum GPU memory

This system suits players who want 32 GB of GDDR7 video memory on the GeForce RTX 5090 for 4K gaming and VR workloads. The 64 GB DDR5 capacity also helps with heavy multitasking or content creation alongside gaming. Buyers who only need 1080p or 1440p performance, or who prefer a lower-wattage build with a smaller power supply, should consider a different configuration.

GeForce RTX 5090 with 32 GB GDDR7

The graphics card provides 32 GB of GDDR7 memory on a PCI Express x16 interface and is marked Virtual Reality Ready. This single specification determines whether the PC matches a buyer's target resolution and VRAM-dependent workloads.

Questions about this item

What real-world speed does the 5.7 GHz boost clock on the Core Ultra 9 285K deliver inside the C301 GLASS?

The 5.7 GHz boost clock is the maximum single-core frequency the Intel Core Ultra 9 285K can reach under load, giving peak responsiveness in games and bursty workloads. Sustained all-core speeds will be lower and depend on the 240 mm liquid cooler's thermal headroom.

How does the PCI Express x16 slot limit the GeForce RTX 5090 in this build?

The graphics card connects through a PCI Express x16 interface, providing full lane width for the RTX 5090. No narrower link or chipset bottleneck is present, so the GPU can saturate its 32 GB GDDR7 memory bandwidth without interface constraints.

Will the 240 mm liquid cooler and RTX 5090 both fit in the Gigabyte C301 GLASS chassis?

The C301 GLASS case is designed around a 240 mm liquid cooler for the CPU and has clearance for full-length graphics cards such as the RTX 5090. The 1200 W power supply is also housed internally, so all listed components mount without modification.
