A liquid-cooled gaming desktop with a 16-core Ryzen 9 9950X3D, 32 GB DDR5, 4 TB NVMe storage and an RTX 5070 graphics card
This system pairs a 16-core AMD Ryzen 9 9950X3D processor with an Nvidia GeForce RTX 5070 graphics card. It ships with 32 GB of DDR5 memory and a 4 TB NVMe SSD. The mid-tower chassis uses liquid cooling and includes Windows 11 Pro. It targets enthusiasts who want high single-thread speed and modern GPU features in a ready-to-run build.
The Samsung 990 PRO SSD operates over a PCIe 4.0 x4 link, capping sequential throughput at the drive’s rated speeds. Wireless networking uses Wi-Fi 7 2x2, while wired LAN is 2.5 GbE. Rear I/O provides two USB4 ports at 40 Gbps alongside assorted 10 Gbps and 5 Gbps USB sockets. Internal expansion relies on four M.2 slots and two SATA ports.
Builders moving from an 8-core processor gain double the core count and a larger L3 cache for multi-threaded workloads. Replacing a PCIe 3.0 NVMe drive removes the bandwidth ceiling that limits large-file transfers. The 850 W power supply supports the current GPU and leaves headroom for a single graphics upgrade. Buyers who need more than 32 GB of RAM or a second graphics card should look elsewhere.

The system ships with 32GB DDR5 across four slots. The X870 motherboard supports up to 192GB total, so you can add modules later if workloads demand more capacity.
Sixteen cores and 32 threads at 4.3GHz base, boosting to 5.70GHz with 128MB L3 cache, give strong multi-threaded throughput for rendering, compilation and heavy multitasking.
Sequential reads reach 7450 MB/s and writes 6900 MB/s over the PCIe 4.0x4 link, so large game loads and project transfers stay quick.
