Integrated Radeon graphics handle display output through HDMI and two USB4 ports without a discrete card.

Storage Throughput and Interface Ceilings

The 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s over a PCIe 4.0 x4 link. The 10TB hard drive adds bulk capacity at SATA 6Gb/s speeds. Rear I/O includes two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports, four USB 2.0 ports, and Intel 2.5Gb Ethernet alongside Wi-Fi 7 and Bluetooth 5.4.

Compatibility Checklist Before Ordering

Verify that your monitors accept HDMI or USB4 DisplayPort alt-mode signals, as no discrete GPU outputs are present. The mid-tower chassis measures 477 x 220 x 486 mm and supports three 3.5-inch and three 2.5-inch internal drives plus one external 5.25-inch bay. The motherboard offers four DDR5 slots with a 192 GB ceiling and four M.2 connectors for future expansion.

Questions about this item

Should I pick the 4 TB NVMe or the 10 TB hard drive for my main games?

Install the OS and active titles on the 4 TB Samsung 990 PRO for 7450 MB/s reads; use the 10 TB drive with 256 MB cache for media and backups.

What does the 4.4 GHz base clock deliver once the CPU is under load?

The 12-core Ryzen 9 9900X3D boosts to 5.50 GHz with 128 MB L3 cache, so heavy workloads run well above the base frequency.

How fast are the two USB4 ports on the X870 motherboard in practice?

Each USB4 port runs at 40 Gbps, capping external SSD transfers at that ceiling while sharing the controller bandwidth.
