Custom liquid-cooled gaming workstation

This Adamant Custom desktop pairs a 6-core AMD Ryzen 5 9600X processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 128GB of DDR5 memory and a combined 8TB of NVMe storage across two Samsung 990 PRO drives. Windows 11 Pro is pre-installed on the 240mm liquid-cooled system.

Suited for high-memory creative workloads

The 128GB DDR5 capacity and 32GB GPU frame buffer serve professionals editing large timelines, training local models or running heavy simulations. Buyers who need more than 128GB of system memory or multiple graphics cards should look at a platform with higher memory limits and additional PCIe slots.

128GB DDR5 memory installed

Four slots are populated to reach 128GB, leaving no free slots for simple expansion. The motherboard supports up to 192GB total, so any increase requires replacing existing modules. Verify your application's memory ceiling before purchase.

Questions about this item

What does the 5.40 GHz boost clock mean for actual workloads on this Ryzen 5 9600X?

The 6-core CPU can reach 5.40 GHz on single-threaded tasks, while the 240 mm liquid cooler keeps temperatures stable during sustained multi-core loads such as rendering or compiling.

How does the PCI Express x16 slot and motherboard layout affect the RTX 5090 and storage speeds?

The PRIME X870-P board wires the GPU at full x16 speed and provides four M.2 sockets; the two installed Samsung 990 PRO drives each deliver up to 7450 MB/s read and 6900 MB/s write over four lanes.

Will the Antec P20 case and 1000 W power supply handle the RTX 5090 and liquid cooler together?

The mid-tower measures 469 x 220 x 490 mm with front 120 mm fans and dust filters, while the 80 PLUS Gold 1000 W unit supplies the GPU and 240 mm AIO with Japanese capacitors and over-voltage protection.
