Core Specification

This is a new tower desktop built around a 12-core AMD Ryzen 9 9900X3D processor reaching 4.4 GHz base frequency with up to 5.50 GHz boost. It ships with 128GB DDR5 memory across four slots, an 8TB NVMe array using two 4TB Samsung 990 PRO drives, and a 10TB HDD. Graphics come from an Nvidia GeForce RTX 5070 with 12GB VRAM, cooled by a 240mm liquid loop and powered by an 850W 80 PLUS Bronze PSU.

Ideal Buyer And Limits

The system suits professionals who need large local storage and high memory capacity for media editing, simulation or AI-ready workloads, plus gamers who want 1440p performance with headroom for future titles. Buyers who need more than 192GB maximum memory, more than four M.2 slots, or a second graphics card should look elsewhere, as the motherboard and chassis do not support those expansions.

Compatibility Checklist

Verify that your monitors use DisplayPort or HDMI outputs compatible with the RTX 5070, and that any external storage or peripherals match the rear USB mix of two USB4 40Gbps Type-C ports, one USB 10Gbps, three USB 5Gbps and four USB 2.0 ports. The case measures 469 x 220 x 490 mm, so confirm desk or rack space. The motherboard provides Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 wireless; ensure your network infrastructure can use those standards.

Questions about this item

Does the motherboard have enough DDR5 slots to reach the 192 GB maximum without removing the installed 128 GB?

The board provides four DDR5 slots total; 128 GB are already installed, so two slots remain free for future expansion up to the 192 GB limit.

Will the 12 GB RTX 5070 occupy the only PCI Express x16 slot and block any legacy add-in cards I might keep?

The graphics card uses the primary PCI Express x16 slot; the X870 motherboard also includes additional PCIe lanes for other expansion cards, so older hardware can still be added.

After first boot, which indicator confirms the liquid cooler is circulating properly?

The 240 mm AIO pump runs from a dedicated motherboard header; verify the CPU temperature stays near idle levels in the BIOS hardware monitor to confirm flow.
