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 graphics card. It is built for professionals who need high multi-thread throughput for rendering, modelling and AI learning workloads. The tower chassis uses liquid cooling to manage heat from the CPU and GPU under continuous demand.

Sustained Load Behaviour

A 360mm liquid cooler and case fans rated at 1500rpm and 30dBA keep temperatures stable during long compile, training or render sessions. The 1200W 80 PLUS Gold power supply delivers steady power without throttling. Two Samsung 990 PRO SSDs in RAID provide up to 7450 MB/s read and 6900 MB/s write speeds that do not degrade over extended transfers.

192GB DDR5 Capacity Decides Fit

The motherboard supports a maximum of 192GB across four slots and this build populates every slot. Buyers who need more memory capacity cannot expand further without replacing modules. The 8TB NVMe array and 10TB hard drive offer large active and archive storage, but the memory ceiling is fixed at the factory configuration.

Questions about this item

How loud are the 140 mm case fans when the system runs continuously?

Both the front pair and the single rear 140 mm fan spin at 1500 rpm and are rated at 30 dBA each, so total chassis airflow noise stays at a low office-friendly level.

What display cable must I already own to use the RTX 5090 32 GB?

The graphics card uses modern DisplayPort and HDMI outputs; you will need a compatible DisplayPort or HDMI cable that matches your monitor's input.

Can the four SATA ports on the Z890 motherboard still run my older 3.5-inch mechanical drives?

Yes, the board provides four SATA 6 Gb/s connectors that work with any standard 3.5-inch or 2.5-inch SATA hard drive or SSD.
