The X870 motherboard rear panel provides two USB4 40 Gbps Type-C ports, three 10 Gbps ports, four 5 Gbps ports and one 2.0 port, plus internal headers for 20 Gbps and 5 Gbps USB. Four M.2 slots and two SATA 6 Gbps ports support the included 2 TB NVMe SSD and 10 TB hard drive.

Professional GPU with 32 GB memory

The Nvidia RTX PRO 4500 Blackwell card delivers 32 GB of video memory over a PCI Express x16 link, suited for large assemblies and GPU-accelerated simulation. System memory is 128 GB DDR5 with a 192 GB maximum on the platform. The 850 W 80 PLUS Bronze power supply and 2.5 Gb Ethernet plus Wi-Fi 7 connectivity complete the platform.

Questions about this item

What USB standard does the rear USB4 port use and what throughput does it cap at?

The rear panel has two USB4 ports each rated at 40 Gbps using USB Type-C connectors.

How much internal clearance does the case provide for a liquid-cooling radiator?

The 240 mm AIO cooler is pre-installed; the case measures 474 mm deep by 215 mm wide by 454 mm high.

Which motherboard headers must be connected during the AIO installation and what is the common mistake?

Connect the pump header and the fan header to the X870-PLUS TUF board; the step often missed is plugging the pump into the dedicated CPU-pump header instead of a standard fan header.
