Built for rendering and AI workloads

This workstation combines a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. A 4TB NVMe SSD and 10TB hard drive provide fast primary storage and high-capacity secondary space. Windows 11 Pro is pre-installed on the system.

Verify motherboard clearance and power capacity

The mid-tower chassis measures 475mm deep, 245mm wide and 463mm high with a 360mm liquid cooler installed. Ensure your workspace accommodates these dimensions and that the 1200W power supply meets local voltage requirements. The board uses an LGA 1851 socket and offers four memory slots supporting up to 192GB total.

Suits creators needing GPU compute

Buyers who require maximum single-thread frequency or a smaller form factor should consider alternative configurations. Users without 2.5GbE or Wi-Fi 7 infrastructure will not benefit from the onboard network hardware.

Questions about this item

What comes inside the Ceres 300 case and what must I add myself?

The workstation ships fully assembled with the 24-core Ultra 9 285K, 64GB DDR5, 4TB Samsung 990 PRO NVMe, 10TB HDD, RTX 5090 32GB, 1200W PSU, 360mm liquid cooler, Windows 11 Pro and Wi-Fi 7. No extra parts are required for operation.

Should I choose the 64GB DDR5 configuration or plan for the 192GB maximum?

The board has four slots populated with 64GB today. If your rendering or AI workloads regularly exceed that capacity, order the 192GB option now; otherwise the 64GB kit leaves two slots free for a later upgrade.

What does the 7450 MB/s SSD read figure mean once the system is running?

That is the Samsung 990 PRO PCIe 4.0x4 sequential read ceiling. Real-world project loads, OS boot and texture streaming will be lower but still far faster than any SATA drive.
