Gaming desktop with Ryzen 9 9900X3D and RTX 5090

This tower system pairs a 12-core Zen 5 processor with 128MB L3 cache and a GeForce RTX 5090 32GB GDDR7 graphics card. It is built for enthusiasts who run 4K games, VR titles and heavy content-creation workloads on Windows 11 Pro. Buyers needing a compact chassis or integrated graphics should look elsewhere.

1200W power supply and 360mm liquid cooling under

A 1200W PSU feeds both the CPU and the 32GB GDDR7 GPU while a 360mm AIO cooler manages processor thermals during extended sessions. The Shadow Black case uses RGB fans to move air across the 128GB DDR5 memory and 4TB PCIe NVMe SSD without throttling. Systems limited to air cooling or lower-wattage units will not sustain these clocks.

128GB DDR5 memory capacity decides fit

The platform ships with 128GB of DDR5 DIMMs installed across the available slots. This capacity supports large texture streaming, multi-app workflows and virtual-machine hosting without paging. Users who require more than 128GB of system memory cannot expand further on this motherboard.

Questions about this item

How loud and hot does the 1200W PSU and 360mm AIO get when the Ryzen 9 9900X3D and RTX 5090 run all day?

The 1200W power supply and 360mm liquid cooler are sized for the 12-core Ryzen 9 9900X3D and RTX 5090 32GB GDDR7, keeping thermals and fan noise controlled during extended gaming or rendering sessions.

What display and peripherals do I need to add before this tower is usable?

No monitor is included, so you must provide your own screen plus keyboard and mouse; the system offers HDMI, three DisplayPort outputs and multiple USB 2.0 and USB 3.2 Type-C ports for those peripherals.

Will my older USB 2.0 headset and 1080p monitor work with the HDMI and USB ports on this PC?

Yes, the four USB 2.0 ports and HDMI output are backward-compatible, so legacy headsets, keyboards and 1080p displays connect and function without adapters.
