Custom workstation with 12-core Ryzen 9 9900X3D

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 128GB of DDR5 memory, a 4TB NVMe SSD and a 10TB hard drive. The system targets professionals who need high core counts and large GPU memory for modelling, editing, rendering or AI learning workloads.

Suited for multi-threaded production

The 24-thread CPU and 32GB GPU frame buffer handle complex simulations, video timelines and training batches that exceed typical gaming requirements. Buyers who only need high frame rates in games or who require ECC memory support should evaluate alternatives that match those specific needs.

Liquid-cooled CPU maintains clocks during extended

A 240mm quiet-edition AIO cooler manages the processor thermals while the Cooler Master HAF 500 case moves air through front 200mm ARGB fans and a rear 120mm fan. The 1200W 80 PLUS Gold power supply delivers stable output through long compute sessions without thermal throttling.

Questions about this item

Do I need to supply my own monitor, keyboard and mouse for this Ryzen 9 9900X3D RTX 5090 system?

Yes, the desktop tower ships without a display or input devices. Connect any monitor with HDMI or DisplayPort and standard USB peripherals to the rear I/O panel.

Can I keep my existing SATA SSDs and 3.5-inch hard drives when moving to this X870 motherboard?

The board provides four SATA 6Gb/s ports and the case includes two internal 3.5-inch bays, so current SATA drives fit directly.

How do I verify the 128GB DDR5 kit is running at its rated speed after first boot?

Open Task Manager’s Performance tab or the UEFI BIOS and confirm the memory frequency matches the DDR5 specification shown for the installed modules.
