Liquid-cooled 24-core Intel Core Ultra 9 workstation with 64GB DDR5 and 8TB NVMe PRO SSD storage
This desktop pairs a 24-core Intel Core Ultra 9 285K with 64GB DDR5 and an 8TB NVMe array in a tower chassis. Liquid cooling and a 360mm radiator keep the processor stable under sustained multi-threaded loads. It targets professionals who need high single-thread frequency and large memory capacity without a discrete graphics card. The system ships with Windows 11 Pro and Wi-Fi 7 connectivity.
Four DDR5 slots hold 64GB today and support up to 192GB for future expansion. Dual 4TB Samsung 990 PRO drives deliver sequential reads up to 7450 MB/s and writes up to 6900 MB/s over PCIe 4.0. Integrated graphics share system memory, so heavy 3D rendering or GPU compute workloads will exhaust both VRAM and bandwidth quickly. The platform suits code compilation, virtualization and large dataset analysis instead.
The TUF Gaming Z890 motherboard provides Thunderbolt 4, USB 20Gbps and 10Gbps ports, four M.2 sockets and four SATA 6Gb/s connectors. A Thermaltake Smart 850W 80 PLUS Bronze unit powers the build, while front and rear 140mm fans move air through the Ceres 300 case. Builders who require a discrete GPU must supply their own card and verify physical clearance. The integrated HDMI and DisplayPort outputs handle desktop display duties.

Yes, the motherboard has four DDR5 slots in total and supports up to 192 GB, so you can populate the remaining two slots with compatible DDR5 modules.
The 360 mm AIO uses a 140 mm fan rated at 1500 rpm and 30 dBA; you should hear a low hum and see coolant temperature stabilise in the BIOS or monitoring software.
The box contains the assembled tower with CPU, 64 GB DDR5, dual 4 TB Samsung 990 PRO SSDs, Z890 motherboard, 850 W PSU, liquid cooler, Windows 11 Pro licence and Wi‑Fi 7 / Bluetooth 5.4 antennas; you only need to add a monitor, keyboard and mouse.
