Core specification

This system is a 12-core liquid-cooled gaming desktop built around an AMD Ryzen 9 9900X3D processor running at 4.4 GHz. It ships with 32 GB of DDR5 memory and an 8 TB NVMe array configured as two 4 TB Samsung 990 PRO drives. A Radeon RX 9070 XT graphics card with 16 GB of video memory handles visual output. Windows 11 Pro is pre-installed.

Build integration

The Antec P20 mid-tower case measures 469 mm deep by 220 mm wide by 490 mm high and includes three 120 mm front fans plus dust filters on the bottom, front and top. A 240 mm quiet-edition AIO cooler is mounted for the CPU. The Thermaltake Smart 850 W 80 PLUS Bronze power supply uses a 140 mm fan and Japanese main capacitors. The PRIME X870-P motherboard provides four M.2 slots, two SATA ports and front-panel USB 3.0, USB 3.2 Gen 2 Type-C and audio connections.

Ideal buyer

This configuration suits professionals and enthusiasts who want a ready-to-run workstation with high multi-threaded CPU performance, large fast storage and a modern GPU in a compact tower. Buyers who need more than 32 GB of memory out of the box, additional 3.5-inch drive bays beyond the two provided, or a higher-wattage power supply for extreme overclocking should look at other options.

Questions about this item

How far can the Ryzen 9 9900X3D boost before the 240 mm liquid cooler hits its thermal ceiling?

The CPU is rated up to 5.50 GHz with 128 MB L3 cache; the 240 mm Quiet Edition AIO is sized for that sustained load.

What noise and heat should I expect from the Thermaltake 850 W Bronze PSU and 140 mm fan during all-day operation?

The PSU uses a 140 mm ultra-quiet fan and Japanese main capacitors; the 240 mm AIO is labelled Quiet Edition for low noise under continuous load.

Which display cables must I already own to use the Radeon RX 9070 XT 16 GB?

The GPU connects via PCI Express x16; you will need a DisplayPort or HDMI cable that matches your monitor’s input.
