A liquid-cooled tower packing a 16-core Ryzen 9 9950X, 32 GB DDR5, 1 TB NVMe plus 10 TB HDD, and a Radeon RX 9070 XT for high-end gaming and creative work
This desktop pairs a 16-core AMD Ryzen 9 9950X processor with a Radeon RX 9070 XT graphics card and 32 GB of DDR5 memory. It targets creative professionals and enthusiasts who need strong multi-threaded compute plus modern GPU performance in a single tower running Windows 11 Pro.
The CPU is cooled by a 360 mm quiet-edition AIO that arrives pre-filled and mounted, so no tubing work is required. The tempered-glass case opens without tools, yet the dense front 140 mm fan array and 850 W bronze PSU cabling can make reaching the lower M.2 slot or SATA ports awkward once the GPU is seated.
Under continuous all-core CPU and full GPU load the 850 W 80 Plus Bronze unit operates near its rated capacity, so fan speed rises noticeably after several minutes. The 360 mm radiator keeps the 16-core chip at stable clocks, but the power supply’s thermal headroom becomes the limiting factor for indefinite heavy rendering or compute sessions.

Open the BIOS or a hardware monitor such as HWInfo and watch the CPU package temperature; under load it should stay well below the 95 °C throttle point, and the pump RPM reported by the motherboard should be steady and non-zero.
The system ships with the X870 motherboard, 16-core CPU, 360 mm AIO cooler, 32 GB DDR5, 1 TB Samsung 990 PRO NVMe, 10 TB HDD, Radeon RX 9070 XT 12 GB GPU, 850 W PSU, Wi-Fi 7 and Windows 11 Pro pre-installed; a display, keyboard, mouse and speakers are not included.
The 1 TB Samsung 990 PRO delivers up to 7 450 MB/s read and 6 900 MB/s write for OS and active projects, while the 10 TB mechanical drive adds bulk capacity for archives; if you need more high-speed space, the motherboard provides three M.2 slots for additional NVMe drives.
