NZXT N7 B650E motherboard unboxing

The “N7 B650E” is NZXT’s latest-generation AMD motherboard, following their B550 chipset model. The first-generation N7 B550 was introduced in mid-2021 and supported AMD Ryzen 3000, 4000, and 5000 series processors with the AM4 socket.

The NZXT N7 B650E, on the other hand, supports AMD’s most recent AM5 socket. Users can pair it with the new Ryzen 7000 series processors to take advantage of features such as 4x DDR5 memory, a PCIe 5.0 x16 graphics card slot, PCIe Gen5 x4 SSD, and other performance enhancements and expanded specifications.

The ATX variant of the N7 B650E offers ample expandability, catering to the demands of both everyday mainstream users and dedicated PC DIY enthusiasts. Its 30.5 x 24.4cm ATX size is compatible with most mid-tower cases. The N7 series’ most prominent aesthetic feature is its minimalist-style heatsink. In contrast to competing products that employ gaming-oriented designs and RGB elements, the NZXT N7 consistently delivers a refined and elegant appearance to users.

There is no additional reinforced backplate behind the motherboard.

The N7 B650E features a 16+2+1 configuration of 90A/60A Smart Power Stage (SPS) power supply, with an L-shaped heatsink for efficient heat dissipation of the power supply chip. The motherboard incorporates the new AM5 LGA 1718 socket, which eliminates the issue of bent pins due to processor collisions. However, users should still be cautious when handling the motherboard to protect the pins.

In terms of design, AMD has maintained the same mounting distance between AM5 and AM4, allowing users to easily reuse their existing AM4 cooling solutions. This enables them to save some money by using their old coolers when upgrading to a new system configuration.

A robust VRM heatsink aids in heat dissipation and ensures efficient performance for the 90A power supply.
The AM5 LGA 1718 socket is featured on the motherboard, and the heatsink clip is compatible with the AM4 specification.

I’ll start by providing an overview of the paper specifications, and then we’ll take a closer look at the various expansion slots of the N7 B650E. An 8+4 Pin CPU ATX_12V power supply slot is located in the top-left corner of the motherboard.

An ATX_12V 8+4 Pin CPU power supply socket is situated in the top-left corner of the motherboard.

The CPU_FAN, AIO_PUMP, and NZXT_RGB1/2 connectors are arranged in the upper right corner of the motherboard from left to right. The N7 B650E offers multiple NZXT_RGB connectors, making it an ideal choice for NZXT water cooling and fans! Moreover, if you’re using an all-in-one water cooling solution, it is recommended to connect the water cooling pump to the AIO_PUMP connector first, as this slot is preconfigured to run at full speed.


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

When purchasing memory, it’s recommended to opt for a 2 DIMM dual-channel memory kit, typically sold as a pair. Install the memory modules in the A2 and B2 slots (the second and fourth slots from the left). Placing the memory modules in these positions enables them to operate at higher frequencies more easily.

The motherboard features a four-slot single-clip DDR5 memory slot, supporting 128GB memory expansion and both EXPO and XMP 3.0 overclocking technologies.

On the right side of the N7 B650E motherboard, you’ll find two chassis fan connectors (SYS_FAN1/2), a 24-Pin motherboard power supply connector, a front Type-C USB 3.2 Gen2x2 (20Gb/s) ports, two USB 3.2 Gen1 headers (supporting a total of four front USB 3.2 Gen1 ports), and four SATA3 6Gb/s connectors.

EZ Debug can rapidly determine self-test outcomes, identifying issues related to the CPU, DRAM, VGA, BOOT, or any other undetected problems.

The motherboard’s PCIe slots consist of three x16 slots in total; however, only the first one (PCIEX16_1) offers full x16 bandwidth. The metal-reinforced PCIEX16_1 slot supports PCIe 5.0 x16 specifications, ensuring ample structural strength and full bandwidth for direct installation of graphics cards.

The second and third x16 slots (PCIEX16_2/PCIEX16_3) have an installation length of x16, but they actually provide only x2 bandwidth. These slots can be used to expand additional devices such as capture cards or sound cards. However, be cautious not to make a mistake when installing graphics cards in these slots, as they do not offer full bandwidth!

The motherboard features a PCIe 5.0 x16 metal-reinforced graphics card slot and two PCIe 4.0 x16 slots, each with x2 bandwidth.

The B650E features a total of three M.2 SSD expansion slots. The M.2_1 slot, which is directly connected to the processor, supports PCIe Gen5 x4 bandwidth. A robust SSD heatsink offers adequate cooling performance for the PCIe Gen5 M.2 SSD.

The second and third M.2_2/M.2_3 slots support PCIe Gen4 x4 bandwidth and PCIe Gen4 x2 bandwidth, respectively. All three M.2 SSD installation positions are compatible with 2242/2260/2280 length specifications.
