System overview

The Adamant Custom desktop is a liquid-cooled gaming PC built around a 24-core Intel Core i9-14900K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. It ships with 32GB of DDR5 RAM and a 2TB Samsung 990 PRO NVMe SSD. The system targets enthusiasts who want a high-end workstation and gaming machine ready for Windows 11 Pro out of the box.

Platform limits

The Z790 PRIME motherboard provides four DDR5 slots with a maximum supported capacity of 192GB, so the installed 32GB kit leaves room for expansion. Storage connectivity includes three M.2 connectors and four SATA 6Gb/s ports, while the rear I/O offers USB 3.2 Gen 2, USB 3.2 Gen 1 and USB 2.0 ports. Network access relies on Intel 2.5Gb Ethernet, Wi-Fi 6 and BLUETOOTH 5.2; no faster wired or wireless standards are present.

Build and connectivity

The Corsair 4000D tempered-glass case measures 490 x 239 x 486 mm and houses a 360mm quiet-edition AIO cooler for the CPU. A Thermaltake Toughpower 1200W 80 PLUS Gold unit with a 140mm fan supplies power and includes over-voltage, under-voltage, over-power and short-circuit protection. Front-panel I/O provides one USB 3.2 Type-C port, two USB 3.2 Gen 1 ports and a combo audio jack, while internal bays accommodate two 3.5-inch and two 2.5-inch drives.

Questions about this item

Should I pick the 32 GB DDR5 option or upgrade to the 192 GB maximum?

The system ships with 32 GB DDR5 across four slots. If you run memory-heavy workloads such as large-scale rendering or virtualization, moving toward the 192 GB ceiling will prevent swapping; for gaming and general creative work the factory 32 GB is already ample.

What does the i9-14900K's 6.00 GHz boost mean for daily performance?

The 24-core, 32-thread CPU can hit 6.00 GHz on its fastest cores, giving snappy single-thread response for game logic and app launches while the remaining cores chew through background compiles, streams or encodes without slowing the foreground task.

How fast is the Samsung 990 PRO over its PCIe 4.0x4 link?

The drive is rated for 7450 MB/s reads and 6900 MB/s writes on the PCIe 4.0x4 interface, so game loads, texture streaming and large file copies run at near-peak Gen 4 speeds without bottlenecks.
