System Identity

This is a 12-core liquid-cooled desktop built around an AMD Ryzen 9 9900X3D and an Nvidia RTX 5070. It ships with 192GB of DDR5 memory and a 4TB NVMe SSD. The combination targets creators and engineers who need multi-threaded compute alongside modern GPU acceleration in a single mid-tower chassis.

Build Compatibility

The motherboard uses an AM5 socket and provides four memory slots, all populated to reach the 192GB maximum. Primary storage occupies one M.2 slot; three additional M.2 connectors remain open for expansion. The 850W power supply carries 80 PLUS Bronze certification and includes the necessary PCIe connectors for the installed graphics card. Front-panel I/O includes USB4, USB 10Gbps and USB 5Gbps ports.

Sustained Operation

A 240mm liquid cooler handles the CPU thermal load during extended rendering or simulation runs. The case moves air through three 120mm front fans while dust filters protect intake paths. The power supply’s 140mm fan runs quietly under continuous load thanks to its Japanese main capacitor and protection circuitry. Windows 11 Pro 64-bit manages background tasks without interrupting long-duration workloads.

Questions about this item

Does the PC ship with a keyboard and mouse, or do I need to buy them separately?

The system includes the tower, power cord and Windows 11 Pro licence only; a keyboard and mouse are not supplied and must be purchased separately.

Is the 192 GB DDR5 configuration the maximum this motherboard supports, or can I add more later?

The PRIME X870-P board has four slots and a 192 GB ceiling, so this build already reaches the limit; no further memory can be added.

What does the 7 450 MB/s read speed of the 4 TB Samsung 990 PRO mean for everyday workloads?

That sequential rate lets large project files, game assets and video footage load in seconds rather than minutes, keeping the 12-core Ryzen 9 9900X3D fed with data.
