24-Core Ultra 9 Workstation

This system pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It targets professionals who need high single-thread frequency up to 5.70 GHz for rendering, modelling and AI learning workloads. The Gigabyte Z890 UD motherboard provides the platform foundation.

Storage and Connectivity Bundle

A 2TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec for active projects. A 10TB hard drive with 256MB cache adds bulk capacity for archives. Wi-Fi 6E and Bluetooth5.3 join 2.5Gbps LAN for flexible networking. Windows 11 Pro 64-bit is pre-installed.

Pre-Built Liquid-Cooled Desktop

The PC arrives fully assembled inside a Corsair 4000D case with a 360mm quiet-edition AIO cooler already mounted on the LGA 1851 socket. A 1200W 80 Plus Gold power supply with a 140mm fan handles the 24-core CPU and RTX 5090 combination. Builders who prefer to install their own cooling loop or who need a smaller chassis should consider a bare-bones alternative.

Questions about this item

Will the 1200W 80 PLUS Gold PSU need replacement if I run the RTX 5090 and 285K at full load continuously?

The 1200W 80 PLUS Gold unit with Japanese main capacitors and 140mm ultra-quiet fan is rated for sustained high-load operation and includes over-voltage, under-voltage, over-power and short-circuit protection.

What thermal limit will the 360mm AIO liquid cooler hit first when the 24-core Ultra 9 285K sustains 5.70 GHz across all cores?

The 360mm Quiet Edition AIO is designed to handle the 285K's heat output at up to 5.70 GHz; the coolant temperature rise under full load is the first limiting factor before any throttle point.

How loud is the 140mm PSU fan and 360mm AIO radiator fans when the system runs all day at maximum throughput?

The PSU uses a 140mm ultra-quiet fan and the CPU cooler is a 360mm Quiet Edition AIO; both are specified for low noise levels during continuous operation.
