System overview

This Adamant Custom desktop combines a six-core AMD Ryzen 5 9600X processor with an Nvidia GeForce RTX 5090 graphics card and 128GB of DDR5 memory. It targets creators and professionals who need high single-thread speed, large video memory and fast storage for rendering, simulation or AI workloads.

Installation notes

The PC ships fully assembled with Windows 11 Pro installed and a 240mm liquid cooler already mounted on the CPU. First boot only requires attaching peripherals and connecting power. The Antec P20 case uses tempered glass panels; handle them carefully when opening the chassis for future upgrades.

Compatibility checks

Verify that your monitor has a DisplayPort or HDMI input capable of the resolution and refresh rate you intend to run. The motherboard provides four M.2 slots and two 3.5-inch bays, so confirm physical space before adding more drives. The 1000W Gold-rated PSU uses standard ATX cables; ensure any replacement unit matches the form factor and connector layout.

Questions about this item

How do I verify the liquid cooler and RTX 5090 are running correctly after first boot?

Enter the UEFI on the PRIME X870-P motherboard to confirm the 240 mm AIO pump speed and the Ryzen 5 9600X temperature, then open GPU-Z or Task Manager to see the RTX 5090 32 GB detected on the PCI Express x16 slot.

Which components are already inside the Antec P20 case and what must I add?

The build includes the Ryzen 5 9600X, 128 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX 5090 32 GB, 1000 W 80 PLUS Gold PSU, Wi-Fi 7, Windows 11 Pro — only a display, keyboard and mouse are required.

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

The system ships with 128 GB DDR5 installed across the four slots; the X870-P motherboard can reach 192 GB if you later replace modules, but 128 GB is already high capacity for gaming and workstation workloads.
