24-Core Liquid-Cooled Gaming Tower

The Adamant Custom desktop pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card in a Corsair 4000D tempered-glass tower. A 360 mm quiet-edition liquid cooler handles the CPU while the system ships with Windows 11 Pro pre-installed. It targets enthusiasts who want a fully assembled, high-core-count machine for gaming and heavy multitasking without building it themselves.

Dual 4 TB NVMe and 1200 W Gold PSU

Two Samsung 990 PRO 4 TB drives combine for 8 TB of PCIe 4.0 storage, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. The Thermaltake Toughpower 1200 W 80 PLUS Gold unit uses a Japanese main capacitor and a 140 mm fan with over-voltage, under-voltage, over-power and short-circuit protection. These components remove the need to source a high-wattage power supply or additional fast storage separately.

Z790 Connectivity and Internal Expansion

The Z790 PRIME motherboard provides rear USB Type-C, USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports plus internal headers for another Type-C, two USB 3.2 Gen 1 and two USB 2.0 connections. Networking covers Intel 2.5 Gb Ethernet, Wi-Fi 6 and BLUETOOTH 5.2. Four SATA 6 Gb/s ports and three M.2 slots remain open alongside two 3.5-inch and two 2.5-inch drive bays for future upgrades. Builders needing more than 192 GB of DDR5 memory or a second graphics card should look elsewhere.

Questions about this item

Will the 360 mm AIO liquid cooler need its coolant topped up or the pump replaced over time?

The 360 mm AIO is a sealed unit; no coolant top-ups are required, and the pump is rated for continuous operation without scheduled replacement.

Which component hits its thermal ceiling first during an all-core 6.00 GHz workload — the CPU or the radiator?

The i9-14900K 24-core processor will reach its thermal junction limit before the 360 mm radiator and 140 mm fan assembly saturate.

How loud is the 140 mm PSU fan and the AIO pump when the system runs at full load all day?

The Thermaltake 1200W Gold PSU uses an ultra-quiet 140 mm fan and the 360 mm AIO is a Quiet Edition design, both built for low noise under sustained load.
