ASROCK B450M/Ac Wifi DDR4 AMD Motherboard

The ASRock B450M/AC WiFi is a Micro-ATX motherboard built around the AMD B450 (Promontory) chipset and designed for AMD AM4 socket processors, including Ryzen series (Summit Ridge, Pinnacle Ridge, Raven Ridge, Picasso, and Matisse) as well as AMD Athlon series APUs. Its compact 9.6-inch × 9.6-inch (24.4 cm × 24.4 cm) form factor makes it suitable for space-conscious builds without sacrificing connectivity or feature depth. Connectivity is a core strength of this board. An Intel 802.11ac dual-band WiFi module (supporting IEEE 802.11a/b/g/n/ac at 2.4 GHz and 5 GHz) delivers wireless connections at speeds up to 433 Mbps, and Bluetooth 4.2 is included on the same module. For wired networking, a Realtek RTL8111H Gigabit LAN controller (10/100/1000 Mb/s) handles reliable Ethernet with Wake- LAN and Energy Efficient Ethernet (802.3az) support. Memory support is provided through four DDR4 DIMM slots using dual-channel technology, with a maximum system memory capacity of 64 GB. Depending on the installed CPU, frequencies range from DDR4 2133 up to DDR4 3200+ (OC), with XMP profile support also included. A 9-phase digital power design and a premium 42A power choke underpin stable power delivery to the processor. Storage options include one Ultra M.2 socket (M2_1) supporting M Key type 2242/2260/2280 modules at up to PCIe Gen3 x4 (32 Gb/s) with compatible Ryzen CPUs, plus four SATA3 6.0 Gb/s connectors with RAID 0, RAID 1, and RAID 10 support. Expansion slots comprise one PCIe 3.0 x16 and one PCIe 2.0 x16 (operating at x4 mode) with AMD Quad CrossFireX support. Audio is handled by a Realtek ALC892 codec delivering 7.1-channel HD audio with ELNA audio capacitors for reduced noise. The single HDMI 1.4 port supports display output at up to 4K (3840×2160) @ 30 Hz when paired with an APU. Rear I/O includes 4× USB 3.2 Gen1 and 2× USB 2.0 ports, alongside the HDMI, RJ-45, and audio jacks. ASRock Polychrome SYNC manages onboard RGB and addressable RGB headers, allowing synchronisation with compatible accessories. The board carries FCC and CE certifications and ships with a 3-year warranty.
