Core specification

This system is built around a 24-core Intel Core i9-14900K processor with 32 threads and a 6.00 GHz maximum turbo frequency. It targets creators and power users who need high single-thread speed and heavy multi-thread throughput in a pre-assembled tower. The 128 GB DDR5 memory and 1 TB Samsung 990 PRO SSD are installed and ready for immediate workloads.

Build integration

The Antec P20 mid-tower case uses a 360 mm liquid cooler for the CPU and includes three 120 mm front fans with dust filters on the bottom, front and top. A Thermaltake Smart 850W 80 PLUS Bronze power supply with a 140 mm fan delivers power to the Z790 TUF motherboard, which provides four M.2 slots, four SATA ports and multiple USB 3.2 Gen 2 and Gen 1 ports on the rear and mid-board. Integrated graphics drive displays via HDMI and DisplayPort.

Capacity and headroom

The 128 GB DDR5 configuration occupies four slots on a board that supports up to 192 GB, leaving no free DIMM sockets for further memory expansion. The single 1 TB NVMe drive uses one M.2 slot; three additional M.2 connectors and two 3.5"/2.5" internal bays remain available for extra storage. Integrated graphics handle desktop output and light GPU compute but cannot accelerate modern 3D rendering or gaming workloads.
