Built for 12-core workloads and 4K assets

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a 4TB NVMe SSD. A GeForce RTX 5060 graphics card handles display output. The system ships with Windows 11 Pro installed and uses a 240mm liquid cooler on the CPU.

Verify AM5 motherboard clearance and PSU cables

The mid-tower case measures 469mm deep by 220mm wide by 490mm high and holds an ATX board with four memory slots. The 850W 80 PLUS Bronze power supply uses a 140mm fan and provides the PCIe connectors required by the RTX 5060. Front-panel ports include USB 3.2 Gen 2 Type-C and two USB 3.0 sockets.

Replaces a workstation limited to 64GB RAM

Builders moving from a platform capped at 64GB of memory or reliant on SATA SSDs gain quadruple the capacity and PCIe 4.0 speeds up to 7450 MB/s read. The jump is worth it when projects demand 128GB of DDR5 and sustained NVMe throughput for large media timelines or simulation datasets.

Questions about this item

Does the system ship with a keyboard and mouse or do I need to buy them separately?

The box contains the Antec P20 mid-tower PC with liquid CPU cooler, Windows 11 Pro pre-installed and a power cord; keyboard and mouse are not included.

Should I pick the 128 GB DDR5 configuration or the 192 GB maximum the board supports?

128 GB DDR5 fills all four slots at high speed; 192 GB would require slower modules and is only useful for extreme memory workloads.

What does the Ryzen 9 9900X3D 4.4 GHz base clock deliver in actual workloads?

Twelve cores and twenty-four threads with 128 MB L3 cache boost to 5.50 GHz, giving strong multi-threaded performance for rendering and compilation.
