System identity

The Adamant Custom desktop is a new mid-tower gaming PC built around an 8-core AMD Ryzen 7 9800X3D processor with 192GB of DDR5 memory and a 4TB NVMe SSD. It ships with Windows 11 Pro and relies on integrated Radeon graphics for display output through HDMI and USB4 ports. The configuration targets users who need high core-count CPU performance and large memory capacity without a discrete graphics card.

Thermals and power

A 240mm liquid cooler handles the CPU while three 120mm front fans and a 140mm power supply fan move air through the Antec P20 case. The Thermaltake Smart 850W 80 PLUS Bronze unit delivers power with Japanese main capacitors and protections against over-voltage, under-voltage, over-power and short circuit. Dust filters on the bottom, front and top help keep internal components clean during normal operation.

Deciding specification

The system uses integrated AMD Radeon graphics instead of a discrete GPU, so buyers who need dedicated video memory, hardware video encoding or higher 3D performance should look elsewhere. The 192GB DDR5 limit matches the motherboard maximum, leaving no room for future memory upgrades. Wireless connectivity is provided by Wi-Fi 7 and Bluetooth 5.4.

Questions about this item

How do I install the 240mm AIO liquid cooler and what step is often missed?

Mount the radiator to the case top or front using the included fans, then attach the pump block to the AM5 socket with the pre-applied thermal paste — many builders forget to remove the plastic cover on the cold plate before seating it.

What maintenance or replacement will the 240mm AIO liquid cooler need later?

The sealed loop is maintenance-free for its service life; after several years you may replace the whole unit if pump noise rises or coolant loss reduces cooling on the Ryzen 7 9800X3D.

What limit appears first under sustained load on the Ryzen 7 9800X3D with this 240mm AIO?

The 240mm radiator surface area caps heat dissipation, so CPU package temperature hits its thermal ceiling before the 850W PSU or 192GB DDR5 memory become bottlenecks.
