24-Core Ultra 9 Workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K with 128GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. The Z890 TUF motherboard provides Thunderbolt 4 and Wi-Fi 7 connectivity. Two 4TB Samsung 990 PRO drives deliver 8TB NVMe storage. It targets professionals who need high core counts and large video memory for rendering, modelling and AI learning workloads.

Sustained Load Behaviour

A 360mm liquid cooler handles the CPU during extended compute sessions while the 1200W 80 PLUS Gold PSU maintains stable power delivery. Case airflow uses four 140mm fans rated at 1500rpm and 30dBA each. The motherboard power phases and VRM heatsinks are designed for continuous all-core operation at up to 5.70 GHz boost clocks without thermal throttling.

Interface Practical Limits

PCIe 4.0 x4 caps each 990 PRO SSD at 7450 MB/s read and 6900 MB/s write throughput. The 2.5Gbps Ethernet and Wi-Fi 7 2x2 wireless links share the same Intel controller. Thunderbolt 4 provides a single 40Gbps Type-C port for external peripherals. Total DDR5 capacity can reach 192GB across four slots when future expansion is required.

Questions about this item

How loud is the 140mm case fans and 360mm liquid cooler when the Intel Core Ultra 9 285K runs all day?

The front and rear 140mm fans each spin at 1500rpm and produce 30dBA. The 360mm Quiet Edition AIO is designed for low noise under sustained load.

Which display cables must I already own to use the GeForce RTX 5090 32GB?

The RTX 5090 uses DisplayPort and HDMI outputs. You will need a compatible DisplayPort or HDMI cable that matches your monitor's input.

Can I keep my existing SATA SSDs and 2.5-inch drives with the Z890 motherboard?

Yes. The board provides four SATA 6Gb/s ports and the Ceres 300 case includes bays for two 2.5-inch drives.
