ASRock B650M PG Lightning AMD AM5 Motherboard

The ASRock B650M PG Lightning delivers reliable performance for AMD Ryzen 7000 and 9000 series processors in a compact Micro-ATX form factor. Built on the AMD B650 chipset, this motherboard combines essential features with robust power delivery for gaming and productivity builds.

Power Delivery and Memory Support

Equipped with a 6+2+1 power phase design featuring Dr.MOS technology, the B650M PG Lightning provides stable power delivery to AMD AM5 processors. The integrated power stage solution offers improved thermal performance compared to traditional discrete MOSFETs, ensuring consistent operation under load.

Four DDR5 DIMM slots support dual-channel memory configurations up to 7200MHz+ with AMD EXPO and Intel XMP profiles. The 6-layer PCB design enables stable memory overclocking, with maximum capacity reaching 256GB for demanding workloads.

Storage and Expansion

Storage flexibility comes from three M.2 sockets: one Blazing M.2 slot supporting PCIe Gen5 x4 (128Gb/s), one Hyper M.2 slot with PCIe Gen4 x4 (64Gb/s), and one M.2 socket with PCIe Gen4 x2 (32Gb/s). Four SATA3 ports provide additional connectivity for legacy drives. The PCIe 5.0 M.2 slot delivers twice the bandwidth of Gen4, ready for next-generation SSDs.

Expansion options include one PCIe 4.0 x16 slot with steel reinforcement for graphics cards, one PCIe 3.0 x16 slot (x4 mode), and an M.2 Key-E socket for WiFi modules. The reinforced steel slot provides extra anchor points and signal stability for heavy graphics cards.

Connectivity Features

Phantom Gaming 2.5Gb/s LAN powered by Dragon RTL8125BG delivers 2.5X the bandwidth of standard gigabit Ethernet, with automatic game traffic detection and acceleration. USB connectivity includes one USB 3.2 Gen2 Type-C port (10Gb/s), one USB 3.2 Gen2 Type-A port (10Gb/s), and multiple USB 3.2 Gen1 ports across front and rear I/O.

Integrated AMD RDNA graphics output through HDMI 2.1 and DisplayPort 1.4 supports 4K 120Hz resolution with HDR and HDCP 2.3. Realtek ALC897 7.1 CH HD audio codec with Nahimic Audio technology provides enhanced sound quality for gaming and media.

BIOS and Software Features

The 256Mb AMI UEFI BIOS includes ASRock's Blazing OC Tuner, which automatically switches between manual OC mode and AMD Precision Boost Overdrive based on CPU current thresholds. BIOS Flashback button enables easy firmware updates without CPU installation. ASRock Auto Driver Installer simplifies initial system setup by pre-installing LAN drivers for network-based driver installation.
