Core Ultra 5 245K Workstation

This desktop ships new with a 14-core Intel Core Ultra 5 245K processor that reaches 5.20 GHz. A 240 mm liquid cooler keeps the CPU stable under sustained loads. The system targets professionals who need workstation-class throughput in a standard tower form factor.

128 GB DDR5 Upgrade Path

Four memory slots are populated with 128 GB of DDR5, leaving no empty slots for simple expansion. The motherboard supports up to 192 GB total, so a capacity increase requires replacing existing modules. The jump is worthwhile when current workloads exceed available RAM headroom.

1 TB NVMe and 32 GB GPU Headroom

A Samsung 990 PRO 1 TB drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s. The GeForce RTX 5090 provides 32 GB of video memory for large models and high-resolution assets. Storage runs out when active project libraries exceed the single terabyte.
