Ryzen 9 9900X3D 12-Core Liquid Cooled Workstation

This new tower desktop combines a 12-core AMD Ryzen 9 9900X3D processor with a 360mm liquid cooler and 32GB DDR5 memory. It targets professionals and enthusiasts who need strong multi-threaded CPU performance without a discrete graphics card. The system ships with Windows 11 Pro and an 8TB NVMe storage array.

8TB NVMe Storage Across Two Samsung 990 PRO Drives

The boot and data volume consists of two 4TB PCIe 4.0x4 SSDs delivering up to 7450 MB/s read and 6900 MB/s write speeds. This capacity and throughput suit large project files, game libraries and content-creation workloads. No mechanical hard drive is included and no additional drive bays are described.

Sustained CPU Performance Under Liquid Cooling

The 360mm quiet-edition AIO keeps the 12-core processor at high frequencies during extended render, compile or simulation tasks. Integrated AMD Radeon graphics handle display output via HDMI and two USB4 ports but are not suited for heavy 3D workloads. Buyers who need dedicated GPU acceleration should look elsewhere.

Questions about this item

What does the 12-core Ryzen 9 9900X3D running at 4.3 GHz deliver inside this tower?

The 12-core processor reaches 5.50 GHz boost with 128 MB L3 cache and 24 threads, all cooled by a 360 mm liquid loop for sustained multi-threaded workloads.

What does the USB4 interface on the X870 motherboard cap at for external drives?

Two rear USB4 ports run at 40 Gbps each, so a single NVMe enclosure will hit the controller limit before the port does.

What clearance and power connections does the 360 mm AIO need in the Antec P20 case?

The 360 mm radiator mounts in the front with three 120 mm fans, powered from the 850 W PSU and the motherboard CPU fan header.
