Liquid-cooled desktop with an 8-core Ryzen 7 9800X3D, 64 GB DDR5, 4 TB NVMe storage and Radeon RX 9070 XT graphics
This Adamant Custom gaming desktop arrives assembled with Windows 11 Pro installed. The eight-core Ryzen 7 9800X3D processor reaches 5.20 GHz boost with 96 MB L3 cache. A 240 mm liquid cooler keeps thermals low inside the Antec P20 mid-tower case. Sixty-four gigabytes of DDR5 memory and a 4 TB Samsung 990 PRO NVMe drive provide capacity for large projects and modern titles.
The PRIME X870-P motherboard offers one PCI Express x16 slot wired for the installed Radeon RX 9070 XT 16 GB graphics card. Builders who need a second full-length card or error-correcting memory should look at workstation-class platforms. Four memory slots support up to 192 GB total for future expansion. Rear I/O includes USB4 40 Gbps ports, 2.5 Gb Ethernet and Wi-Fi 7 wireless.
Thermaltake Smart 850 W unit delivers 850 W through a single 140 mm fan with over-voltage, under-voltage, over-power and short-circuit protection. Japanese main capacitor and bronze efficiency rating define the sustained load the system can support. Any upgrade that pushes total draw above this limit will require a higher-capacity supply.

The system includes a 240 mm AIO radiator; the Antec P20 mid-tower supports 240 mm radiators in the front or top, so it fits without modification.
Plug the pump header into the CPU_FAN connector and set the header to PWM mode in BIOS so the pump runs at full speed.
The 140 mm PSU fan and the three 120 mm front case fans are the only moving parts besides the pump; expect to replace fans before the SSD or GPU.
