Custom liquid-cooled workstation

This Adamant Custom desktop pairs an eight-core AMD Ryzen 7 9700X processor with 128GB of DDR5 memory and a 240mm liquid cooler. The system ships with Windows 11 Pro installed and is built for professional workloads that demand sustained multi-threaded performance.

Quiet mid-tower with extensive I/O

The Antec P10 FLUX case uses sound-dampening panels and a 140mm PSU fan alongside three front 120mm fans and a rear 120mm fan. Rear connectivity includes two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports, four USB 2.0 ports and Intel 2.5Gb Ethernet. The Prime X870-P motherboard adds internal USB headers, four M.2 slots and two SATA 6Gb/s connectors for further expansion.

Professional GPU with limited video memory

The Nvidia RTX A400 provides four Mini DisplayPort outputs for multi-monitor setups but carries only 4GB of VRAM, restricting texture-heavy rendering and large-frame-buffer compute tasks. Storage combines a 2TB Samsung 990 PRO NVMe drive with sequential reads up to 7450 MB/s and a 10TB hard drive with 256MB cache for bulk data. The 750W 80 PLUS Bronze power supply delivers protected power for the configured components.

Questions about this item

What PCIe generation does the X870 motherboard run the RTX A400 at, and what bandwidth does that cap the card to?

The board wires the GPU slot as PCIe 4.0 x16, so the RTX A400 is limited to roughly 32 GB/s of theoretical bandwidth.

What case clearances and PSU connectors are required for the 240 mm liquid cooler and RTX A400?

The Antec P10 FLUX accepts a 240 mm radiator up front and the 750 W PSU includes the necessary PCIe power cables for the A400.

How is the 128 GB DDR5 kit installed on the four-slot X870 board, and which slot order do builders often get wrong?

Populate all four DIMM slots with the matched 128 GB kit; the manual specifies slots two and four first, then one and three, which many installers reverse.
