16-Core Ryzen 9 Workstation

This new desktop combines a 16-core AMD Ryzen 9 9950X3D processor with 128GB of DDR5 memory and a 4TB NVMe SSD. It targets creators and gamers who need high multi-threaded throughput and fast storage in a single mid-tower system. The liquid-cooled CPU and GeForce RTX 5070 12GB GPU handle demanding workloads and modern titles. Windows 11 Pro is pre-installed.

DDR5 Platform Limits

The motherboard provides four DDR5 slots with a maximum supported capacity of 192GB, so the installed 128GB kit leaves room for future expansion. Storage uses a PCIe 4.0 x4 interface, capping sequential reads at 7450 MB/s and writes at 6900 MB/s. Rear I/O includes USB4 at 40Gbps, 10Gbps and 5Gbps USB ports, plus 2.5Gb Ethernet and Wi-Fi 7 connectivity. Internal bays accept two 3.5-inch and two 2.5-inch drives.

850W Bronze Power Supply

The Thermaltake Smart 850W 80 PLUS Bronze unit delivers the system's power with Japanese main capacitors and a 140mm low-noise fan. Protections cover over-voltage, under-voltage, over-power and short-circuit conditions. This wattage and efficiency rating determine whether the build can sustain full CPU and GPU load without throttling or instability. Builders needing higher headroom for additional cards or extreme overclocking should verify the limit.
