A 16-core liquid-cooled desktop with 32GB DDR5, 4TB NVMe plus 10TB HDD and an RTX 5070 Ti for high-end gaming and creative work
This desktop pairs a 16-core AMD Ryzen 9 9950X processor with 32GB of DDR5 memory and an Nvidia GeForce RTX 5070 Ti graphics card. A 360mm liquid cooler manages CPU thermals inside a mid-tower chassis. The system ships with Windows 11 Pro installed and includes Wi-Fi 7 connectivity.
The boot drive is a 4TB Samsung 990 PRO NVMe SSD rated for sequential reads up to 7450 MB/s and writes up to 6900 MB/s. A 10TB hard drive with 256MB cache adds bulk capacity for archives and media. Four M.2 slots on the motherboard allow further NVMe expansion up to the platform limit of 192GB memory.
A Thermaltake Smart 850W 80 PLUS Bronze unit powers the build with over-voltage, under-voltage, over-power and short-circuit protection. The Corsair 4000D chassis provides two internal 3.5-inch and two 2.5-inch bays, front USB 3.2 Type-C and Type-A ports, and tempered glass side panel. Rear I/O includes two USB4 ports, one USB 10Gbps, three USB 5Gbps, four USB 2.0, Intel 2.5Gb Ethernet and audio jacks.
