12-Core Liquid-Cooled Workstation

This Adamant Custom gaming desktop ships new with a 12-core AMD Ryzen 9 9900X3D processor boosted to 5.50 GHz and 128 MB of L3 cache. A 240 mm quiet-edition liquid cooler keeps thermals in check inside an Antec P20 mid-tower case. The system includes 128 GB of high-performance DDR5 memory across four slots and runs Windows 11 Pro out of the box.

Upgrade From Integrated-Graphics Builds

The board provides two USB4 ports at 40 Gbps, three USB 10 Gbps ports, four USB 5 Gbps ports and a 2.5 Gb Ethernet jack alongside Wi-Fi 7 and Bluetooth 5.4. Builders moving from a platform without USB4 or 2.5 Gb LAN gain high-speed peripheral bandwidth and modern wireless. The jump is worth it when workflows need 40 Gbps external storage or low-latency 802.11be connectivity.

8 TB NVMe Plus 10 TB HDD Headroom

Twin 4 TB Samsung 990 PRO drives deliver sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active projects, while a 10 TB hard drive with 256 MB cache stores bulk media. The motherboard offers four M.2 connectors and two SATA ports for further expansion. Integrated Radeon graphics handle display output via HDMI and the two USB4 ports but will not satisfy buyers who need discrete GPU compute or ray-tracing acceleration.

Questions about this item

What clearance does the Antec P20 case provide for the 240 mm liquid cooler radiator?

The case measures 469 mm deep, 220 mm wide and 490 mm high, with 120 mm front fan mounts that accept the 240 mm radiator and three pre-installed 120 mm fans.

Which motherboard power connectors must be seated for the Ryzen 9 9900X3D on the TUF X870-PLUS, and what step is often missed?

Connect the 850 W PSU 24-pin ATX and the 8-pin EPS cables; the EPS connector is frequently left loose, preventing the CPU from reaching 5.50 GHz boost.

When will the Samsung 990 PRO 4 TB SSDs or the 10 TB HDD likely need replacement?

The SSDs are rated for PCIe 4.0 speeds of 7450 MB/s read and 6900 MB/s write; monitor SMART health and plan replacement once endurance limits approach.
