Built for 12-core creative workloads

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. The system ships with Windows 11 Pro and an 8TB NVMe storage array built from two 4TB Samsung 990 PRO drives. Liquid cooling keeps the CPU stable during long rendering or compile sessions.

Steps up from 8-core or air-cooled builds

Moving from an 8-core CPU to this 12-core design adds 50 percent more threads for parallel tasks such as video encoding or virtualisation. The 240mm liquid cooler replaces a standard air tower, lowering thermal resistance so the processor can hold higher frequencies longer. The jump is worth it when your current workstation throttles during sustained multi-core loads.

Sustained load behaviour with liquid cooling

Under continuous load the 240mm AIO maintains lower coolant temperatures than an air cooler, allowing the Ryzen 9 9900X3D to stay near its 5.50 GHz boost ceiling without hitting thermal limits. The Thermaltake 850W Bronze power supply delivers stable current to both CPU and GPU during extended sessions. The Antec P20 case moves air through three front 120mm fans and dust filters to keep internal temperatures steady over hours.

Questions about this item

Will the 469 mm deep Antec P20 case fit on my desk?

The chassis measures 469 mm deep by 220 mm wide by 490 mm high, so allow at least that footprint plus cable clearance behind the rear I/O panel.

What is the trickiest step when adding more DDR5 memory later?

The motherboard has four slots total; populate the two empty slots first and enable EXPO in the BIOS or the new modules may run at base speed.

When should I plan to clean the 240 mm liquid cooler radiator?

Vacuum the radiator fins every 6 to 12 months through the front dust filter to keep the 140 mm fan airflow unrestricted.
