Overview
The NZXT N7 B550 (model N7-B55XT-B1) is an ATX-form-factor motherboard built on the AMD B550 chipset and designed for the AM4 socket. It is compatible with AMD Ryzen 3000, 4000, and 5000 Series processors — note that the Ryzen 5 3400G and Ryzen 3 3200G APUs are not supported. The board ships in a distinctive matte-black cover finish that integrates an I/O shield directly into the rear panel, simplifying the build process and giving the interior a cleaner appearance. Connectivity is a highlight. Wireless networking is handled by an Intel AX210 adapter supporting Wi-Fi 6E across 2.4 GHz, 5 GHz, and 6 GHz bands with 802.11 a/b/g/n/ac/ax protocols and MU-MIMO, paired with Bluetooth 5.2. Wired networking uses a Realtek RTL8125BG 2.5 Gigabit LAN controller. The rear I/O panel provides 1 x USB 3.2 Gen 2 Type-C, 3 x USB 3.2 Gen 2 Type-A, 4 x USB 3.2 Gen 1, and 2 x USB 2.0 ports, alongside an HDMI 2.1 output, optical S/PDIF, 5.1-channel audio jacks, a BIOS Flashback button, and a Clear CMOS button. Memory support extends to four DDR4 DIMM slots with a maximum capacity of 128 GB. Base speeds of 2133–3200 MHz are complemented by XMP support and overclocked profiles reaching 4666+ MHz on Vermeer and Matisse CPUs and 4733+ MHz on Renoir APUs. Both ECC and non-ECC unbuffered memory types are supported in a dual-channel configuration. Storage options include one M.2 slot (2242/2260/2280, PCIe 4.0 x4 on Vermeer/Matisse or PCIe 3.0 on Renoir) and a second M.2 slot (PCIe 3.0 x2 and SATA mode), plus six SATA 6 Gb/s ports with RAID 0/1/5/10 support. Expansion slots comprise one PCIe x16 (PCIe 4.0 x16 on Vermeer/Matisse), one PCIe x16 (x4 mode), and two PCIe 3.0 x1 slots, with 2-Way AMD CrossFireX multi-GPU support. Audio is delivered by a Realtek ALC1220 codec providing 8-channel high-definition audio at 32-bit/192 kHz through Nichicon Fine Gold Series audio capacitors. Thermal and lighting management run through NZXT CAM software, which controls four RGB channels (via 2 x NZXT RGB, 1 x 5V ARGB, and 1 x 12V RGB headers) and seven independent fan channels (one CPU_FAN, one AIO_PUMP up to 24 W, and five SYS_FAN connectors each up to 24 W).
