Ready-to-game desktop with 24-core Ultra 9 285K

This ArsenalPC system ships fully assembled inside a Gigabyte C301 Glass chassis. The Intel Core Ultra 9 285K runs at 5.7 GHz across 24 cores, paired with an NVIDIA GeForce RTX 5090 carrying 32 GB GDDR7. Windows 11 Home is pre-installed on the 2 TB NVMe SSD, and 128 GB of DDR5 memory fills all four slots for immediate high-resolution gaming and content creation.

Sustained load on liquid-cooled 24-core CPU

A 240 mm liquid cooler handles the Ultra 9 285K under continuous multi-threaded workloads, keeping clock speeds stable during long render or compile sessions. The RTX 5090 maintains its boost profile through extended gaming or GPU compute tasks, fed by the 1200 W power supply. The 128 GB DDR5 array eliminates paging pressure, so memory-intensive pipelines run without throttling or swap-induced stalls.

Thermals, acoustics and power in daily use

The closed-loop 240 mm cooler moves heat from the CPU to the radiator with minimal fan noise at typical desktop loads. Case airflow through the C301 Glass panel exhausts GPU waste heat, keeping internal temperatures low while the 1200 W unit operates well within its efficiency band. Power draw scales with the active workload, and the system remains quiet during standard productivity tasks.

Questions about this item

How loud and hot does the 240mm liquid cooler keep the Intel Core Ultra 9 285K during all-day loads?

The 240mm liquid cooler is designed to handle the 24-core CPU at 5.7GHz, keeping temperatures and noise controlled during extended sessions.

Does the motherboard provide four DDR5 slots so I can expand beyond the installed 128GB later?

Yes, the board includes four DDR5 slots and all are populated with the 128GB kit, so future expansion would require replacing modules.

Will the 1200W power supply support the RTX 5090 and my existing PCIe storage drives without adapter cables?

The 1200W unit delivers ample headroom for the RTX 5090 and includes native PCIe power connectors for additional NVMe or GPU upgrades.
