Adamant Custom 24-Core Ultra 9 285K Workstation

This Adamant Custom tower is a 2026 gaming desktop built around a 24-core Intel Core Ultra 9 285K processor and liquid cooling. It ships with Windows 11 Pro, 128GB of DDR5 memory, a 1TB NVMe SSD and a GeForce RTX 5090 32GB graphics card. The system targets professionals who need high core counts and large VRAM for rendering, modelling or AI learning workloads.

Who this suits and who should look elsewhere

Creators running multi-threaded render jobs, large dataset modelling or local AI training will use the 24 cores, 128GB DDR5 and 32GB GPU memory. Buyers who only game at 1080p or 1440p will not utilise the compute headroom. Teams needing ECC memory or dual-socket scaling cannot expand this platform. Users wanting internal 3.5-inch drive bays beyond the two provided should consider a larger chassis.

The spec that decides fit

The GeForce RTX 5090 32GB frame buffer is the single figure that determines whether this workstation matches the workload. Projects that exceed 32GB of VRAM will spill to system memory and lose performance. If the target application fits within 32GB, the 24-core CPU and 128GB DDR5 keep data flowing. Verify the VRAM requirement before purchase.

Questions about this item

Will the 360 mm liquid cooler keep the 24-core Ultra 9 285K from throttling during long renders?

The 360 mm Quiet Edition AIO is sized for the 24-core Ultra 9 285K and its 5.70 GHz peak, so sustained all-core workloads stay within thermal limits without throttling.

How loud is the system when the RTX 5090 and CPU run flat-out all day?

The 140 mm PSU fan and the AIO's low-noise pump keep acoustic output low; the case moves enough air that both the 32 GB RTX 5090 and the 24-core CPU remain cool without ramping fan speed to an intrusive level.

Does the motherboard include Wi-Fi 6E and Bluetooth 5.3 so I don't need extra cards?

Yes, the Gigabyte Z890 UD board integrates Wi-Fi 6E AX211 and Bluetooth 5.3, plus Intel 2.5 Gb Ethernet, so no separate network or Bluetooth adapters are required.
