Custom workstation for modelling and AI

This Adamant Custom tower pairs an eight-core Ryzen 7 9800X3D running at 4.7 GHz with 128 GB of DDR5 memory and an RTX 5090 graphics card carrying 32 GB of video memory. The system targets professionals who need local rendering, video editing and AI learning capacity in a single Windows 11 Pro machine. Buyers who require more than 128 GB of RAM or a second GPU should look elsewhere.

Liquid cooling and 1200 W Gold supply

A 240 mm quiet-edition AIO handles the CPU while the CoolerMaster HAF 500 case moves air through two 200 mm front fans, a 120 mm rear fan and a dedicated 120 mm GPU fan. The Thermaltake Toughpower 1200 W 80 PLUS Gold unit uses Japanese main capacitors and a 140 mm fan rated for low noise, with over-voltage, under-voltage, over-power and short-circuit protection. Power draw and acoustic levels will reflect this component set.

Samsung 990 PRO storage and Wi-Fi 7

Two 4 TB Samsung 990 PRO drives deliver up to 7450 MB/s reads and 6900 MB/s writes over PCIe 4.0 x4, supplemented by a 10 TB hard drive with 256 MB cache. The X870-PLUS TUF motherboard adds rear USB4 at 40 Gbps, multiple 10 Gbps and 5 Gbps USB ports, Intel 2.5 Gb Ethernet and Wi-Fi 7 2x2 connectivity. Realtek 7.1 surround audio completes the I/O package.

Questions about this item

How is the 240mm liquid CPU cooler installed, and what step is often missed?

The 240mm AIO cooler mounts to the AM5 socket on the TUF X870-PLUS motherboard. The step often missed is connecting the pump header and ARGB cable to the correct motherboard headers before securing the radiator to the case.

What maintenance or replacement will the 128GB DDR5 memory need later?

The 128GB DDR5 kit fills all four slots on the X870-PLUS board. No routine maintenance is required, but future capacity upgrades would require replacing all four modules since the maximum supported is 192GB.

What limit appears first when the RTX 5090 32GB runs sustained workloads?

The 1200W 80 PLUS Gold PSU delivers up to 1200W. Under continuous full GPU and CPU load, the power supply's thermal protection or the 240mm AIO's heat dissipation capacity will likely throttle performance first.
