ASRock B650 PG Lightning AM5 ATX Motherboard - DDR5, PCIe 5.0
The ASRock B650 PG Lightning is an ATX motherboard for builders running AMD Ryzen 9000, 8000 or 7000 series CPUs who want fast storage, memory overclocking headroom and wired networking without paying for features they won't use. It balances core platform capabilities—PCIe 5.0 M.2, DDR5 dual channel, 2.5G LAN—with a lean feature set, making it a practical choice for productivity and gaming builds that don't require WiFi.
Why this product
PCIe 5.0 M.2 for next-gen NVMe
One Blazing M.2 slot runs at PCIe Gen5x4 speeds, paired with two additional Gen4 M.2 slots and 4 SATA ports for mixed storage.
DDR5 dual channel up to 7200+ MHz
Four DIMM slots support overclocked DDR5 via AMD EXPO and Intel XMP profiles, with a maximum capacity of 256GB.
14+2+1 power phase for stable overclocking
60A SPS ensures clean delivery to the CPU, helping sustained OC efforts stay within thermal and electrical margins.
2.5G wired LAN, no WiFi
Realtek Dragon RTL8125BG LAN provides reliable network connectivity at 2.5 Gbps. For WiFi, add a separate card via the M.2 Key-E slot or PCIe x1.
8-layer PCB and pre-installed I/O shield
Solid construction foundation with integrated rear I/O shield, reducing build friction and improving EMI shielding.

Best for
- Builders who want PCIe 5.0 NVMe support without paying for integrated WiFi.
- Productivity and gaming builds that prioritize stable power delivery and memory overclocking.
- Systems needing wired 2.5G networking and SATA storage alongside modern M.2 slots.
- Overclocking enthusiasts who value a 14+2+1 power phase and 8-layer PCB foundation.
Trade-offs
- Users requiring built-in WiFi; this board omits it entirely and requires an add-on card.
- Builders with limited case space; ATX form factor demands a full-size enclosure.
- Those seeking the highest PCIe lane counts; two x16 and two x1 slots are modest compared to higher-tier AM5 boards.
Derived from the "built for stable and reliable" designing concept, ASRock does not compromise on any details.
All B650 motherboards are built with 8-Layer PCB design, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance up to 7200MHz and beyond by enabling the pre-tested profiles.
Make sure the memory modules are AMD EXPO™/ Intel® XMP capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.
* There are certain risks involved with memory overclocking and may affect your system's stability. Please realize that overclocking should be done at your own risk and expense.
EXPO/XMP profile support may vary by different system configuration, memory modules and motherboard models. Please refer to Memory QVL for the completed support list.
The Blazing OC Tuner allows AM5 CPU to switch between OC mode and PBO(Precision Boost Overdrive) mode when the CPU current hits threshold.
Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.
*The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.
*The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters.
