24-Core Liquid-Cooled Workstation

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with a 360 mm AIO cooler and 128 GB of DDR5 memory. The RTX 5070 graphics card adds 12 GB of VRAM for GPU-accelerated workloads. It ships with Windows 11 Pro on a 1 TB Samsung 990 PRO NVMe drive.

Z890 Platform Connectivity Limits

The Gigabyte Z890 UD motherboard provides one USB4 Type-C port and ten additional USB ports spanning 2.0 to 3.2 Gen 2. Four M.2 slots and four SATA 6 Gb/s ports support RAID 0, 1, 5 and 10. Networking uses Intel 2.5 Gb Ethernet plus Wi-Fi 6E and Bluetooth 5.3.

Upgrade Path From Air-Cooled Mid-Range Builds

Builders moving from air-cooled systems with 64 GB of memory and a smaller SSD gain quieter thermal headroom, double the RAM capacity and PCIe 4.0 NVMe speeds up to 7450 MB/s read. The 850 W 80 PLUS Bronze PSU supports the current configuration; further GPU upgrades would require a higher-wattage unit.

Questions about this item

Should I pick the 128GB DDR5 configuration or upgrade toward the 192GB maximum?

The system ships with 128GB DDR5 across four slots; the Z890 board supports up to 192GB, so you only need to add modules later if your workloads demand more capacity.

What does the 5.70GHz boost clock on the 24-core Core Ultra 9 285K deliver in daily use?

The 5.70GHz maximum turbo gives short bursts of single-thread speed for gaming and app launches, while the 24 cores sustain heavy multi-thread loads like rendering or compilation.

How does the PCIe 4.0x4 link affect the Samsung 990 PRO 1TB SSD in this build?

The M.2 slot runs at PCIe 4.0x4, letting the 990 PRO hit its rated 7450MB/s read and 6900MB/s write speeds without bottleneck.
