Liquid-cooled desktop with 14-core Intel Core Ultra 5 245K, RTX 5070, 32GB DDR5 and 2TB NVMe
The Adamant Custom system pairs a 14-core Intel Core Ultra 5 245K processor with an Nvidia GeForce RTX 5070 graphics card. 32 GB of DDR5 memory and a 2 TB Samsung 990 PRO NVMe SSD provide fast storage and multitasking headroom. Windows 11 Pro 64-bit is pre-installed on the Z890 TUF motherboard.
Verify that the 750 W 80 PLUS Bronze PSU matches the power envelope of any future GPU upgrade. The Cooler Master HAF 500 case measures 508 mm deep by 203 mm wide by 508 mm high, so confirm desk or shelf space before ordering. Four memory slots are present with 32 GB installed, leaving room to expand toward the 192 GB maximum. Two 3.5-inch and two 2.5-inch internal bays remain available for extra drives.
The 240 mm liquid cooler handles the CPU during extended gaming or rendering sessions while the case front 200 mm ARGB fans and rear 120 mm ARGB fan move air through the chassis. GPU thermals benefit from the dedicated 120 mm GPU fan. Wi-Fi 7 and Bluetooth 5.4 maintain stable wireless throughput during long transfers. Realtek 7.1 surround audio and Intel 2.5 Gb Ethernet remain consistent under continuous use.

The system ships fully assembled with the CoolerMaster HAF 500 case, 240 mm liquid CPU cooler, 32 GB DDR5, 2 TB Samsung 990 PRO SSD, RTX 5070 12 GB GPU, 750 W 80 PLUS Bronze PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4. Only a monitor, keyboard and mouse need to be added.
The board provides four DDR5 slots with a 192 GB maximum. The installed 32 GB kit leaves three slots free, so you can add matching modules later without replacing the original kit.
The 12 GB frame buffer and PCIe 4.0 x4 SSD bandwidth keep texture streaming smooth at 1440p, while the 750 W PSU and 240 mm liquid cooler sustain boost clocks during extended sessions.
