24-Core AI-Ready Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and a GeForce RTX 5070 graphics card. Liquid cooling keeps the CPU stable under sustained multi-threaded loads. Windows 11 Pro is pre-installed on a 1TB NVMe drive. The system targets creators and engineers who need high core counts and AI acceleration in a single tower.

360mm Liquid Cooler and 850W PSU

A 360mm quiet-edition AIO cooler replaces a standard air tower, lowering acoustic output during long render or compile sessions. The Thermaltake Smart 850W 80 PLUS Bronze unit supplies overhead for the GPU and all populated memory slots. Front and rear 140mm case fans move air at 1500rpm with a 30dBA rating. No optical drive or mechanical hard drive is fitted.

128GB DDR5 and 1TB NVMe Headroom

Four memory slots are fully populated at 128GB, with the motherboard supporting up to 192GB for future expansion. The Samsung 990 PRO delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. The RTX 5070 provides 12GB of video memory for 1440p gaming and GPU-accelerated workloads. Builders needing more than 1TB of primary storage or a second graphics card must add drives or choose a different chassis.

Questions about this item

Will the 360 mm AIO liquid cooler need its coolant topped up or replaced later?

The 360 mm AIO is a sealed closed-loop unit; no coolant top-ups or replacements are required during its service life.

What thermal limit appears first when the Intel Core Ultra 9 285K runs at its 5.70 GHz boost under sustained load?

The CPU will hit its factory thermal throttle point before the 360 mm AIO reaches its maximum heat-dissipation capacity.

How loud are the case fans when the system runs all day at full load?

Front and rear 140 mm fans are rated at 30 dBA at 1500 rpm, so noise stays at a low hum even during extended heavy workloads.
