Targeted Performance Build

This desktop combines a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an RTX 5090 graphics card holding 32GB of video memory. It is assembled for professionals who run rendering, modelling or AI learning workloads that demand sustained multi-thread throughput and large frame buffers. The mid-tower chassis houses a 4TB NVMe drive and a 10TB hard drive for project storage.

Storage and Cooling Impact

The Samsung 990 PRO SSD delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec, cutting load times for massive assets and reducing checkpoint saves during long training runs. A 360mm liquid cooler keeps the CPU near its 5.70 GHz boost ceiling without the acoustic penalty of high-RPM air towers, while the 1200W Gold-rated supply feeds the GPU and peripherals with headroom for future drive additions.

Integration and Common Issues

The system arrives fully assembled with Windows 11 Pro installed, so first boot only requires attaching peripherals and networking via 2.5Gbps Ethernet or Wi-Fi 6E. Builders should verify that the motherboard BIOS recognises all four memory slots at the rated DDR5 speed and confirm the GPU power cables are seated firmly; loose connectors are the most frequent cause of post-shipment instability.

Questions about this item

Will the 360 mm liquid cooler need coolant topped up or the pump replaced?

The 360 mm AIO is a sealed unit; no coolant top-ups are required. Pump life is typically several years of continuous use.

What thermal limit does the 24-core Ultra 9 285K hit first during long renders?

The CPU can boost to 5.70 GHz, but sustained all-core workloads will reach its thermal ceiling before the 360 mm radiator saturates.

How loud is the 140 mm PSU fan and the AIO when the system runs all day?

The Thermaltake 1200 W Gold unit uses a 140 mm ultra-quiet fan, and the AIO is the Quiet Edition; both are designed for low noise under load.
