Core Configuration

This Adamant Custom desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with an Nvidia GeForce RTX 5090 graphics card holding 32GB of video memory. The system ships with 128GB of DDR5 memory across four slots and a 4TB Samsung 990 PRO NVMe drive. It targets professionals who need heavy compute for modelling, rendering and AI learning alongside high-end gaming.

Thermals and Power

A 240mm quiet-edition liquid cooler handles the CPU while the Cooler Master HAF 500 case moves air through two 200mm front fans, a rear 120mm fan and a dedicated 120mm GPU fan. The Thermaltake Toughpower 1200W 80 PLUS Gold unit uses a 140mm fan and Japanese capacitors to deliver stable power with low acoustic output. Over-voltage, under-voltage, over-power and short-circuit protections are built in.

Build Integration

The ATX TUF X870-PLUS motherboard provides rear USB4 40Gbps Type-C ports, 10Gbps and 5Gbps USB-A ports plus 2.5Gb Ethernet and Wi-Fi 7 connectivity. Internal headers include a USB 20Gbps connector, four M.2 slots and two SATA 6Gbps ports. The case offers two 3.5-inch and two 2.5-inch drive bays for future storage expansion. Windows 11 Pro 64-bit is pre-installed.

Questions about this item

How do I install the 240 mm liquid cooler on the AM5 socket, and what step is often missed?

Mount the AM5 bracket, apply thermal paste, secure the cold plate, then connect the pump header and both radiator fans to the motherboard — the pump header is the step most builders forget.

Which components will need replacement first in the 128 GB DDR5 configuration?

The 240 mm AIO pump typically reaches end of life before the DDR5 modules, Samsung 990 PRO SSD or RTX 5090 GPU, so plan a cooler swap after several years of continuous operation.

What thermal limit appears first when the Ryzen 7 9800X3D runs sustained loads with this cooler?

The 240 mm radiator saturates before the CPU hits its 5.20 GHz boost ceiling, so coolant temperature becomes the limiting factor during prolonged all-core workloads.
