Core Ultra 9 285K workstation with RTX 5080

This liquid-cooled tower combines a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5080 16GB graphics card. It ships with 64GB DDR5 memory, 8TB NVMe SSD storage and a 10TB hard drive, running Windows 11 Pro. The system is built for AI-ready workloads, rendering, modelling and editing in a single chassis.

Suits AI development and high-resolution content

The 24-core CPU and 16GB GPU memory handle large local datasets and complex simulations, while 64GB DDR5 and 8TB NVMe capacity keep active projects on fast storage. Buyers who need more than 192GB total memory or require multiple GPU cards should look at a different platform. The single RTX 5080 limits multi-GPU scaling for distributed training.

24-core Intel Core Ultra 9 285K processor

The CPU delivers 24 cores with a 3.7GHz base clock and up to 5.70GHz boost, alongside 36MB L3 cache on the LGA 1851 socket. This core count and frequency combination determines throughput for parallel rendering, modelling and AI learning tasks. The Z890 motherboard supports DDR5 up to 192GB across four slots for future expansion.

Questions about this item

Does the 1000W power supply leave enough headroom for the RTX 5080 and Core Ultra 9 285K?

The Thermaltake Toughpower 1000W 80 PLUS Gold unit powers the RTX 5080 16GB and 24-core Intel Core Ultra 9 285K with headroom for the 360mm liquid cooler, 64GB DDR5, dual 4TB Samsung 990 PRO drives and 10TB HDD.

Can I keep my SATA SSDs and 3.5-inch hard drives when moving to this Z890 motherboard?

The GIGABYTE Z890M AORUS ELITE WIFI7 board provides four SATA 6Gb/s ports plus two internal 3.5-inch bays, so existing SATA SSDs and mechanical drives install directly.

How do I verify the Samsung 990 PRO SSDs are running at PCIe 4.0 x4 speeds after setup?

Open Task Manager Performance tab or Samsung Magician; each 4TB drive should show sequential read near 7450 MB/s and write near 6900 MB/s, confirming PCIe 4.0 x4 operation.
