Built for 18-core gaming and creation

The MSI Infinite ZS 9NVZ-2261US is a tower desktop built around an AMD Ryzen 9 9950X3D processor with 18 cores and 3D V-Cache, paired with an NVIDIA GeForce RTX 5090 graphics card carrying 32GB of GDDR7 memory on a 512-bit bus. It ships with 32GB of DDR5 system memory and a 2TB M.2 NVMe PCIe Gen4 SSD, running Windows 11 Home. The configuration targets enthusiasts who need high multi-threaded throughput and top-tier rasterisation performance in a single pre-built system.

360 mm liquid cooling inside a 700-series mid-tower

The chassis is the MSI PROSPECT 700RL mid-tower, which houses a 360 mm CPU liquid cooler and four ARGB fans to manage heat from the 18-core CPU and the RTX 5090. A 1300W 80+ Gold power supply delivers headroom for the factory components. Connectivity includes Wi-Fi 6E, Bluetooth 5.4, 2.5GbE LAN, Thunderbolt 4 and USB Type-C ports on the front and rear panels. Four DDR5 UDIMM slots support expansion up to 256GB, and additional M.2 slots are available for storage growth.

Gaming keyboard and mouse included for immediate use

An MSI Gaming keyboard and mouse bundle is supplied in the box, removing the need for separate peripheral purchases at setup. The system also includes a Realtek AL897 7.1 HD audio codec for multi-channel output. VR-ready certification means the graphics subsystem meets the baseline requirements for current head-mounted displays. No monitor is included, so a display must be sourced separately.

Questions about this item

Does the 360 mm liquid cooler keep the Ryzen 9 9950X3D stable during long sessions?

The 360 mm liquid cooler and four ARGB fans are designed to dissipate maximum heat so the 18-core processor stays cool under sustained loads.

How loud and hot does the system get with the RTX 5090 and 1300 W Gold PSU running all day?

Liquid cooling on the CPU and a 1300 W 80+ Gold power supply help manage thermals and keep fan noise lower during extended gaming or rendering.

What DDR5 memory must I already have to expand beyond the installed 32 GB?

The board provides four DDR5 UDIMM slots supporting up to 256 GB total, so any standard DDR5 UDIMM modules can be added.
