System Identity

The Adamant Custom gaming desktop combines a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card. 32GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe SSD provide high-throughput capacity for gaming and media workloads. A 360mm liquid cooler and 1200W 80 PLUS Gold power supply support sustained operation.

Pre-Order Verification

Confirm that your display supports the GPU output standards you require and that your network infrastructure can utilise the 2.5Gbps LAN or Wi-Fi 7 connectivity. The motherboard offers four total DDR5 slots with a 192GB maximum, so future memory expansion is possible. Ensure the 447mm depth and 469mm height suit your intended location.

Bundled Impact

Windows 11 Pro 64-bit arrives pre-installed without bloatware, reducing initial setup time. The Samsung 990 PRO SSD delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for fast asset loading. Front-panel USB 3.2 Gen 2x2 Type-C and rear USB4 Type-C ports enable high-speed peripheral connections.

Questions about this item

Does the desktop come with the liquid CPU cooler already installed, or do I need to buy and fit one myself?

The 360 mm Quiet Edition AIO liquid cooler is pre-installed on the Intel Core Ultra 9 285K, so no separate cooler purchase or fitting is required.

The system ships with 32 GB of DDR5 — is that the maximum supported, or can I add more later?

Four DDR5 slots are provided and the board supports up to 192 GB, so you can expand well beyond the factory 32 GB.

The Samsung 990 PRO SSD is quoted at 7 450 MB/s read — will I see that speed in everyday Windows use?

Peak sequential speeds of 7 450 MB/s read and 6 900 MB/s write are reached on large-file transfers; normal OS and game loads benefit from the low latency of the PCIe 4.0 x4 NVMe drive.
