Built for heavy workloads

This desktop combines an eight-core Ryzen 7 9800X3D processor with a GeForce RTX 5090 graphics card carrying 32GB of video memory. The system ships with 128GB of DDR5 RAM and a pair of 4TB Samsung 990 PRO drives in a RAID-ready NVMe configuration. Windows 11 Pro is pre-installed on the 8TB total storage array.

Stepping up from mid-range workstations

The 96MB L3 cache on the CPU and the 5.20GHz boost clock deliver measurable gains for modelling, video editing and AI learning tasks that saturate lesser processors. Liquid cooling on a 240mm radiator keeps thermals stable during sustained render jobs, while the 1200W 80 PLUS Gold power supply provides headroom for the 5090's peak draw without throttling.

Tower platform with room to grow

The Antec P20 mid-tower case supports E-ATX motherboards and offers two additional 3.5-inch or 2.5-inch drive bays plus two dedicated 2.5-inch slots for future storage expansion. Four DDR5 slots are populated now, leaving the motherboard's 192GB ceiling available if workloads demand more memory. Front-panel I/O includes USB 3.2 Gen 2 Type-C, two USB 3.0 ports and audio jacks, while rear I/O adds two USB4 ports at 40Gbps, 2.5Gbps Ethernet and Wi-Fi 7 connectivity.

Questions about this item

Will the 469 mm deep Antec P20 case fit on my desk?

The case measures 469 mm deep, 220 mm wide and 490 mm high, so check your desk depth against 469 mm before ordering.

Does the 240 mm AIO liquid cooler need any extra mounting steps on the AM5 socket?

The cooler includes an AM5 bracket; the step often missed is removing the plastic cover from the cold-plate before securing the four thumb-screws.

When should I plan to replace the 1200 W Gold PSU in this build?

A quality 1200 W Gold unit typically lasts 7–10 years; watch for fan noise or voltage drift under load as replacement signs.
