Core Ultra 5 245K liquid-cooled workstation

This desktop pairs a 14-core Intel Core Ultra 5 245K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. A 240mm liquid cooler handles the CPU while a 1000W 80 PLUS Gold power supply feeds every component. The system ships with Windows 11 Pro installed and is marketed as AI ready for media workloads.

Verify case clearance and motherboard I/O needs

The Corsair 4000D chassis measures 490mm deep, 239mm wide and 486mm high with tempered glass panels. Internal bays provide two 3.5-inch and two 2.5-inch slots for future storage expansion. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports plus Intel 2.5Gb Ethernet and Wi-Fi 7 wireless.

All-in-one cooler and modular PSU simplify daily use

The 240mm quiet-edition liquid loop arrives pre-filled and maintenance-free, leaving the top panel free for additional fans if desired. Thermaltake Toughpower 1000W unit uses Japanese main capacitors and a 140mm fan with over-voltage, under-voltage, over-power and short-circuit protection. Four M.2 slots and four SATA ports on the Z890 motherboard allow straightforward drive upgrades later.

Questions about this item

Does the Adamant Custom PC arrive with Windows 11 Pro already installed and activated?

Yes, Windows 11 Pro 64-bit is pre-installed on the 1TB Samsung 990 PRO SSD so the system is ready to use immediately.

The spec lists 192GB DDR5 across 4 total slots — is that the maximum this motherboard supports?

Correct, the Z890-PLUS TUF motherboard has 4 slots and the 192GB kit fills them completely; no further memory can be added.

With the RTX 5090 32GB and 1000W 80 PLUS Gold PSU, will I have headroom for sustained 4K workloads?

The Thermaltake Toughpower 1000W unit is rated for the GPU and 14-core CPU together, leaving adequate overhead for continuous high-load operation.
