Built for 24-core workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K with 192GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. Liquid cooling keeps the processor stable under sustained rendering, modelling or AI learning tasks. Windows 11 Pro ships pre-installed on a 2TB Samsung 990 PRO NVMe drive.

192 GB DDR5 maximum

The Z890 motherboard offers four slots and is already populated to its 192 GB limit with high-performance DDR5. No further memory can be added without removing existing modules. Buyers who need more capacity must choose a different platform.

1200 W Gold PSU and Wi-Fi 7

A Thermaltake Toughpower 1200W 80 PLUS Gold unit powers the GPU and CPU with Japanese main capacitors and quiet 140mm cooling. The board includes Intel 2.5Gb Ethernet, Wi-Fi 7 2x2 and Bluetooth 5.4 plus Thunderbolt 4 and multiple 20Gbps and 10Gbps USB ports.

Questions about this item

What does the 24-core Intel Core Ultra 9 285K at 3.7 GHz deliver in a real build?

The 24-core processor reaches 5.70 GHz boost with 36 MB L3 cache, giving strong multi-thread throughput for rendering, modelling and AI workloads while the 360 mm liquid cooler keeps thermals in check.

How does the Thunderbolt 4 Type-C port limit external device speed?

The rear Thunderbolt 4 Type-C runs at up to 40 Gbps, so attached NVMe enclosures or docks are capped by that interface rather than the drive's own 7450 MB/s read potential.

What clearance does the 360 mm liquid cooler and RTX 5090 need inside the Ceres 300 case?

The case measures 475 mm deep, 245 mm wide and 463 mm high with front and rear 140 mm fans, providing room for the 360 mm radiator and the dual-slot RTX 5090 without interfering with the four M.2 slots or four SATA ports.
