NZXT N7 B650E motherboard unboxing

The “N7 B650E” is NZXT’s latest AMD motherboard and follows their first B550 chipset model. The initial N7 B550, released in mid-2021, was compatible with AMD Ryzen 3000, 4000, and 5000 series processors with AM4 sockets.

This time, the NZXT N7 B650E supports AMD’s most recent AM5 socket, allowing users to pair it with the new Ryzen 7000 series CPUs. This combination enables access to features such as 4x DDR5 memory, PCIe 5.0 x16 graphics card slot, PCIe Gen5 x4 SSD, and other cutting-edge specifications for enhanced performance and expansion capabilities.

The ATX variant of the N7 B650E offers ample expandability to cater to both everyday mainstream users and dedicated PC DIY enthusiasts. Its dimensions of 30.5 x 24.4cm make it compatible with most mid-tower cases. The N7 series’ most prominent aesthetic feature is its minimalist heat sink design. Unlike competing products that emphasize gaming style and RGB elements, the NZXT N7 consistently delivers a refined and elegant appearance for users.

The motherboard does not include an extra reinforcement backplate on its rear side.

The N7 B650E features a 16+2+1 configuration with 90A/60A Smart Power Stage (SPS) power supply, and an L-shaped heatsink is employed for cooling the power supply chip. The new AM5 LGA 1718 socket is integrated into the motherboard, which avoids the issue of bent pins caused by CPU collisions. However, users need to take care when storing the motherboard to protect the pins.

Regarding design, AMD has been careful to maintain the same spacing between the AM5 and AM4 sockets. This allows users to essentially reuse their existing AM4 cooling solutions, saving some money by repurposing their old coolers when assembling a new system configuration.

The AM5 LGA 1718 socket is compatible with the AM4 specification for heatsink clips.

To begin, let me provide a brief overview of the specifications before we dive into the expansion slots of the N7 B650E motherboard. The upper left corner of the motherboard features an 8+4 Pin processor ATX_12V power supply slot.

Located in the upper left corner of the motherboard is an ATX_12V 8+4 Pin processor power supply socket.

Moving to the upper right corner of the motherboard, from left to right, you’ll find the CPU_FAN, AIO_PUMP, and NZXT_RGB1/2 slots. The N7 B650E offers several NZXT_RGB slots, making it an ideal choice for users who prefer NZXT water cooling and fans. Moreover, if you’re using integrated water cooling, it is recommended to install the water cooling PUMP in the AIO_PUMP slot initially since the slot is preset to operate at full speed.


As the AMD Ryzen 7000 series processors only support DDR5 memory, the N7 B650E’s 4x DIMM DDR5 single-card memory slot can expand up to 128GB capacity. The maximum capacity of a single DDR5 memory is 32GB, and the memory overclocking frequency is advertised to reach 6000+ MT/s (based on the official memory QVL table). The motherboard also supports AMD EXPO (EXTended Profiles for Overclocking) and Intel XMP 3.0 (Extreme Memory Profile) memory one-click overclocking technology certification.

For optimal performance, it’s recommended to install the two DIMMs dual-channel memory kits in the A2 and B2 slots (the second and fourth slots from the left) that are commonly included in memory orders. Placing the two memories in these positions makes it easier for the memory to operate at higher frequencies.

The N7 B650E motherboard features a four-slot single-clip DDR5 memory slot that can support up to 128GB of memory expansion, as well as EXPO and XMP 3.0 overclocking technology certifications.

On the right side of the N7 B650E motherboard, you’ll find two chassis fan slots (SYS_FAN1/2), the motherboard’s 24-Pin power supply, a front Type-C USB 3.2 Gen2x2 (20Gb/s) slot, two USB 3.2 Gen1 slots (which support the installation of up to four front USB 3.2 Gen1 ports), and four SATA3 6Gb/s slots.

The EZ Debug feature on the N7 B650E motherboard allows for quick identification of self-test results, including any potential CPU, DRAM, VGA, BOOT faults, or undetected issues.

The N7 B650E motherboard includes three PCIe slots, all of which are x16 in length. However, only the first slot (PCIEX16_1) provides a full x16 bandwidth and features a metal-reinforced design with PCIe 5.0 x16 specifications. This slot is suitable for the direct installation of graphics cards, offering both physical strength and full bandwidth.

The second and third x16 slots (PCIEX16_2/PCIEX16_3) have a length of x16 but operate at a bandwidth of x2. These slots are ideal for expanding additional devices such as capture cards or sound cards, but it’s essential to avoid confusion when installing graphics cards.
