System identity

This Adamant Custom gaming desktop pairs a 12-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card carrying 32GB of video memory. A 240mm liquid cooler keeps the CPU at 4.4GHz base speed, while 32GB of DDR5 system memory and a 2TB NVMe SSD provide fast storage and multitasking headroom. Windows 11 Pro is pre-installed on the 2026-build platform.

Who it suits

The machine targets creators and engineers who need high single-thread frequency plus large GPU memory for rendering, simulation or AI workloads. Buyers who want more storage bays than the two 3.5-inch and two 2.5-inch internal slots provide, or who require a second graphics card, should look at a different chassis. The fixed 1200W power supply also limits future GPU upgrades beyond the current card.

Deciding specification

The RTX 5090 with 32GB of dedicated graphics memory is the single component that determines whether this system fits the workload; no other part in the build offers that capacity.

Questions about this item

How do I confirm the liquid cooler is running quietly after first boot?

The 240 mm Quiet Edition AIO uses a 140 mm fan; listen for low noise at idle and watch CPU temperature stay near 4.4 GHz under load.

Which items ship inside the Corsair 4000D case and what must I add myself?

The case arrives with motherboard, CPU, cooler, 32 GB DDR5, 2 TB Samsung 990 PRO, RTX 5090 32 GB, 1200 W PSU and Windows 11 Pro installed; only peripherals and display are separate.

Should I pick the 32 GB DDR5 configuration or expand to the 192 GB maximum later?

Four slots are provided with 32 GB fitted; add matching DDR5 modules up to 192 GB total when workloads need more capacity.
