System purpose

The Adamant Custom desktop pairs a 14-core Intel Core Ultra 5 245K with a Radeon RX 9070 XT graphics card and 64 GB of DDR5 memory. It targets creators and gamers who need strong multi-threaded performance and high frame rates at 1440p or 4K. The 4 TB NVMe drive provides ample space for large project files and game libraries. Buyers who want more storage bays or a second graphics card should look elsewhere.

Build practicalities

The system arrives fully assembled inside an Antec P20 mid-tower with a 240 mm liquid CPU cooler already mounted. The Z890 motherboard offers four memory slots, leaving room to reach the 192 GB maximum if required. Front-panel connectivity includes USB 3.2 Gen 2 Type-C and two USB 3.0 ports. The 850 W power supply covers the installed components; adding further high-draw cards would need a larger unit.

Deciding specification

The Radeon RX 9070 XT with 16 GB of video memory is the single component that determines whether this PC fits the workload. It drives 4K gaming and GPU-accelerated creative tasks such as video encoding or 3D rendering. If the target application relies on Nvidia-specific features or needs more than 16 GB of VRAM, this configuration will not be suitable.

Questions about this item

How do I verify the 240mm liquid cooler is running after I power on the PC?

The pump and radiator fans should spin immediately; you can also watch the CPU temperature settle near idle in the BIOS or Windows 11 Pro task manager.

What components ship inside the Antec P20 case and what must I add myself?

The box contains the complete desktop with Core Ultra 5 245K, 64GB DDR5, 4TB Samsung 990 PRO SSD, Radeon RX 9070 XT 16GB, Thermaltake Smart 850W PSU, Z890-PLUS TUF motherboard, Windows 11 Pro and three pre-installed 120mm front fans; no extra parts are required.

Should I choose the 4TB NVMe PRO SSD or a larger capacity for this build?

The system ships with a single 4TB Samsung 990 PRO PCIe 4.0x4 drive rated at 7450 MB/s read and 6900 MB/s write; the Z890 motherboard provides four M.2 slots if you need more storage later.
