Built for heavy creative and AI workloads

This desktop combines a twelve-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 Ti graphics card. It targets professionals who run modelling, editing, rendering or AI learning tasks alongside gaming. The system ships with Windows 11 Pro and an 850W 80 PLUS Bronze power supply.

Straightforward installation

The tower arrives fully assembled and liquid-cooled, so only power, display and peripheral cables need attaching. Front-panel ports include two USB 3.0, one USB 3.2 Gen 2 Type-C and audio jacks. Common issues are forgetting to seat the graphics card power connectors or leaving the CPU cooler pump header unplugged on the motherboard.

Verify your space, power and monitor setup

The Antec P20 mid-tower measures 469 mm deep by 220 mm wide by 490 mm high and weighs enough to need a sturdy desk. Ensure your mains circuit can sustain the 850W supply and that your display uses HDMI or DisplayPort compatible with the RTX 5070 Ti. The board offers four M.2 slots, two SATA ports and Wi-Fi 7 if you plan further storage or wireless upgrades.

Questions about this item

How do I confirm the 12-core Ryzen 9 9900X3D is boosting correctly after assembly?

Open Task Manager in Windows 11 Pro and watch the CPU frequency; the 12 cores should reach the rated 5.50 GHz under heavy load.

Which drives and cooling parts ship inside the Antec P20 case and what must I add?

Two 4 TB Samsung 990 PRO M.2 SSDs, a 10 TB HDD, a 240 mm liquid CPU cooler, three 120 mm front fans, and an 850 W PSU are pre-installed; no extra storage or cooling is required.

Should I pick the 128 GB DDR5 configuration or the 192 GB maximum supported by the X870 motherboard?

The system ships with 128 GB DDR5 across four slots; choose 192 GB only if your modelling or AI workloads regularly exceed 128 GB of active memory.
