24-Core Ultra 9 Workstation

This desktop 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 sustained multi-threaded compute for rendering, modelling and AI learning workloads. The system ships with Windows 11 Pro on a 2TB Samsung 990 PRO NVMe drive. Buyers who only need mainstream gaming performance will find the specification excessive.

PCIe 4.0 NVMe and Wi-Fi 7 limits

The boot drive uses a PCIe 4.0 x4 interface, so sequential throughput tops out at the drive’s rated 7450 MB/s read and 6900 MB/s write. Wireless connectivity relies on Wi-Fi 7 2x2 with Bluetooth 5.4, which requires a compatible router and client device to reach its advertised throughput. The 2.5Gbps Ethernet port is similarly bounded by switch and cabling quality. No faster storage or wireless standards are supported by this platform.

Pre-built liquid cooling and 1200W power

The CPU is cooled by a factory-filled 360mm AIO, removing the need for manual loop assembly or thermal paste application. A Thermaltake Toughpower 1200W 80 PLUS Gold unit powers the entire build, with cables already routed inside the North tempered glass case. The motherboard offers four M.2 slots and four SATA ports, but only two 3.5-inch and two 2.5-inch drive bays are physically available, so large storage arrays need external enclosures.

Questions about this item

Should I pick the 192GB DDR5 configuration or is there a smaller option?

The system ships with 192GB DDR5 across four slots, reaching the board maximum of 192GB, so no smaller capacity is offered in this build.

What does the 5.70GHz boost clock mean when I am rendering or training models?

The 24-core Ultra 9 285K can hit 5.70GHz on active cores, giving short-burst speed for compile jobs and inference while the 360mm AIO keeps thermals in check.

Will the PCIe 4.0x4 link on the 2TB 990 PRO cap my read speeds in this Z890 platform?

The Samsung 990 PRO is rated 7450MB/s read and 6900MB/s write on PCIe 4.0x4; the Z890 chipset provides that link, so the drive runs at its full rated throughput.
