Liquid-cooled gaming desktop with a 14-core Intel Core Ultra 5 245K, 64GB DDR5, 8TB NVMe plus 10TB HDD, and an RTX 5070 Ti 16GB GPU
This Adamant Custom desktop pairs a 14-core Intel Core Ultra 5 245K processor with 64GB of DDR5 memory and a GeForce RTX 5070 Ti 16GB graphics card. A 240mm liquid cooler manages CPU thermals while the system runs Windows 11 Pro. The specification targets creators and gamers who want high single-thread speed plus multi-thread throughput in a single chassis.
The Z890-PLUS TUF motherboard provides four memory slots with 192GB maximum support, four M.2 connectors and four SATA ports for further expansion. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports plus 2.5Gb Ethernet, while Wi-Fi 7 and Bluetooth 5.4 handle wireless connectivity. An 850W 80 PLUS Bronze PSU powers the platform, and the Ceres 300 case offers a single 3.5-inch or dual 2.5-inch drive bay.
Two Samsung 990 PRO 4TB NVMe drives deliver up to 7450 MB/s reads and 6900 MB/s writes for operating system and active projects, while a 10TB HDD with 256MB cache stores bulk media. Realtek 7.1 surround audio supports headset monitoring. The bundle suits workflows that need fast scratch space and deep archival capacity; buyers who want more internal drive bays or a second graphics card will need a different chassis.
