Core specification and audience

This desktop ships with a 24-core Intel Core i9-14900K processor, 128 GB of DDR5 memory and a 2 TB Samsung 990 PRO NVMe drive. The platform targets content creators and engineers who need sustained multi-threaded throughput and large memory capacity without adding a discrete graphics card. Integrated graphics drive the display outputs, so the system suits workloads that rely on CPU compute rather than GPU acceleration.

Thermals, noise and power

A 360 mm quiet-edition liquid cooler handles the CPU, while the chassis includes three 120 mm front fans and a 140 mm PSU fan rated for low noise. The Thermaltake Smart 850 W 80 PLUS Bronze unit supplies power with Japanese main capacitors and protections for over-voltage, under-voltage, over-power and short-circuit events. Dust filters on the bottom, front and top panels help maintain airflow over time.

Build, connectivity and daily use

The Antec P20 mid-tower offers tempered glass side panels and internal bays for two 3.5"/2.5" drives plus two additional 2.5" drives. Front-panel I/O provides two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and dual audio jacks. Rear I/O adds two USB Type-C, two USB 3.2 Gen 2, four USB 3.2 Gen 1, HDMI, DisplayPort, 2.5 Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2. The motherboard also exposes four SATA 6 Gb/s ports and four M.2 connectors for future storage expansion.

Questions about this item

How do I install the 360mm liquid cooler, and which step do people often miss?

Mount the radiator at the front or top of the Antec P20 case using the included 120mm fans, then connect the pump header to the CPU_FAN connector on the Z790 TUF motherboard so the BIOS can control speed.

What maintenance or replacement will the 360mm liquid cooler need later?

The sealed AIO loop requires no refill; plan to clean dust from the radiator fins and 120mm fans every 6–12 months and replace the unit if pump noise or coolant temperature rise appears after several years.

What limit appears first under sustained load with the 850W Bronze PSU and 24-core i9-14900K?

The Thermaltake Smart 850W 80 PLUS Bronze unit delivers up to 850W continuous; prolonged all-core workloads near 6.00GHz can approach that ceiling, making PSU headroom the first bottleneck.
