A liquid-cooled desktop with a 16-core Ryzen 9 9950X3D, 192GB DDR5, 4TB NVMe and RTX 5070 Ti for gaming and heavy workloads
This mid-tower gaming desktop pairs a 16-core AMD Ryzen 9 9950X3D processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5070 Ti graphics card. The system targets professionals who need high core counts for modelling, video editing and AI workloads alongside gaming performance. Windows 11 Pro is installed and ready for immediate use.
A 360mm liquid cooler handles the CPU while two 140mm PWM fans at the front move air through the tempered-glass case. The TUF X870-PLUS motherboard provides rear USB4 ports at 40Gbps, multiple 10Gbps and 5Gbps USB connections, Intel 2.5Gb Ethernet and Wi-Fi 7 wireless. Internal bays include two 3.5-inch and two 2.5-inch slots for future storage expansion.
The 4TB Samsung 990 PRO PCIe 4.0 drive delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec for fast project loading. A Thermaltake Smart 850W 80 PLUS Bronze power supply with Japanese main capacitors and a 140mm quiet fan powers the build with over-voltage, under-voltage, over-power and short-circuit protection.

The rear panel includes two USB4 Type-C ports rated at 40Gbps each.
The mid-tower measures 447 x 215 x 469 mm and offers two 3.5-inch and two 2.5-inch internal bays.
The radiator attaches to the case with included brackets; the step often missed is connecting the pump header to the CPU_FAN header so the BIOS can control pump speed.
