ASROCK X870 Pro RS

ASROCK X870 Pro RS
The ASROCK X870 Pro RS motherboard, featuring the AMD X870 chipset and an AM5 socket, is the perfect choice for building a high-performance PC with AMD Ryzen 9000, 8000, and 7000 series processors. This ATX board boasts a 14+2+1 phase power design with 80A Dr.MOS for VCore and SOC, ensuring a stable power supply even for the most demanding processors. The memory subsystem includes four DDR5 slots with dual-channel configuration and overclocking potential up to 8000+ MHz via Intel XMP and AMD EXPO profiles. For expansion, it offers one PCIe 5.0 x16 slot for your graphics card and one PCIe 4.0 x16 slot running in x4 mode. Both slots feature a reinforced design to securely hold heavy components.
Key features of the ASROCK X870 Pro RS motherboard
- AM5 processor socket supporting AMD Ryzen 9000, 8000, and 7000 series with a robust 14+2+1 phase power design
- Four DDR5 slots with dual-channel architecture and overclocking potential up to 8000+ MHz using XMP and EXPO profiles
- Three M.2 sockets with different PCIe generations, including a Gen5 x4 slot, and screwless heatsinks with a multi-layer design
- Two USB4 Type-C ports with 40Gb/s speeds, also functioning as DisplayPort outputs for 8K display
- Eight-layer PCB with optimised aluminium heatsinks for power circuits and M.2 storage, including bottom-side heat dissipation
- Realtek 2.5G LAN with intelligent bandwidth management and dedicated modes for gaming, streaming, and web browsing
- Realtek ALC1220 audio codec with 7.1-channel output, Nahimic Audio technology, and an optical S/PDIF connector
Storage options with support for modern standards
The board provides three M.2 slots with different speed profiles: the first Blazing M.2 slot supports PCIe Gen5 x4 with a transfer speed of 128Gb/s, the second Hyper M.2 slot operates with PCIe Gen4 x4 (64Gb/s), and the third Ultra M.2 slot supports both SATA3 and PCIe Gen3 x4 (32Gb/s). All M.2 slots are equipped with a screwless mounting system and multi-layer aluminium heatsinks with a quick-release mechanism. For traditional storage, there are four SATA III connectors with a speed of 6Gb/s, two of which are connected directly to the chipset and two via an ASMedia ASM1061 controller. The system supports RAID 0 and RAID 1 configurations for SATA drives, and RAID 0, RAID 1, and RAID 10 for NVMe storage.
Cooling system for stable operation
The motherboard utilises an optimised aluminium heatsink design for effective heat dissipation from the power circuits. All three M.2 slots are fitted with large aluminium heatsinks featuring anti-drop screws, while the underside of the M.2 sockets benefits from additional cooling dissipated through the PCB. A total of six 4-pin PWM fan connectors and one connector for a water pump (AIO_PUMP) allow you to connect a complete cooling system with intelligent speed control. The board is built on an eight-layer PCB design, which ensures stable signal paths and better heat distribution across the entire board.
Connectivity
The rear panel includes two USB4 Type-C ports with 40Gb/s speeds and support for USB PD 3.0 (15W). These ports also function as graphics outputs, delivering up to 8K resolution at 30Hz. The front-panel USB 3.2 Gen2x2 Type-C connector reaches speeds of 20Gb/s. The board offers four USB 3.2 Gen1 ports on the rear panel, two on the front panel, and nine USB 2.0 ports. Network connectivity is handled by a Realtek Dragon 2.5G LAN controller with a transfer speed of 2.5Gb/s. The Realtek ALC1220 audio codec supports 7.1-channel output, an optical S/PDIF port, and Nahimic Audio technology. The rear panel also features an HDMI 2.1 port with 4K resolution at 120Hz.
Personalisation and user-friendly features
RGB lighting is controlled by one RGB LED header (12V/3A) and three addressable RGB LED headers (5V/3A), compatible with ASRock Polychrome SYNC and SignalRGB. The board includes a flexible integrated I/O shield, a BIOS Flashback button for updating the firmware without a CPU, and an Auto Driver Installer. An M.2 Key E socket supports 2230-type Wi-Fi modules, with antenna mounting points on the rear panel. Graphics outputs consist of an HDMI 2.1 port with HDR and 4K resolution at 120Hz, and two USB4 ports with DisplayPort functionality.
