NZXT N7 Z790 motherboard unboxing

When unboxing the N7 Z790, it’s clear that NZXT has kept up with every update to Intel’s motherboard products, starting with the Z490 chipset. The N7 Z790 supports the latest 12th/13th generation Intel Core i9/i7/i5/i3 processors and DDR5 memory. It also avoids the issue of limited expandability specifications seen in the Z790/Z690 chipsets, clearly differentiating it from the previous N7 motherboards.

The N7 Z790 boasts a 16+1+2 phase 60A Dr.MOS power supply and uses 2oz copper in its PCB for better power supply performance to the processor. It supports DDR5 memory and Intel XMP 3.0 one-key overclocking certification, promising to reach up to 6000+ (OC) MT/s frequency based on the official memory QVL form.

For a wireless connection, it has Wi-Fi 6E and Bluetooth V5.2 for novel transmission specifications. Wired network transmission is facilitated by the Realtek RTL8125BG chipset’s 2.5G LAN. It also has three M.2 PCIe Gen4 x4 slots and four SATA 6Gb/s slots for storage.

There are basic paper specifications and various features on the back.

The N7 Z790 motherboard conforms to the ATX 30.5 x 24.4cm specifications, which is a mainstream size that offers sufficient expansion performance and is compatible with most current mid-tower chassis. Most of the motherboard blocks come with a white metal top cover that fits with NZXT’s minimalist design theme. In addition to the all-white model, there is also an all-black model available for purchase.

The previous generation Z690 chipset introduced two N7/N5 motherboard versions to provide players with more affordable options. The N5 model lacks the metal decorative cover, but this also detracts from the brand’s unique style, which is important to NZXT fans. It’s clear that, in addition to expandability and power supply performance, NZXT’s signature simple appearance cannot be compromised!

Overview of the PCB on the back of the motherboard.

To support overclocking for Intel 12th/13th Core K series processors, the VRM power supply block of the motherboard comes with an L-shaped heat sink to ensure sufficient heat dissipation for the 16+1+2 phase 60A Dr.MOS power chip underneath. This feature allows players to use the motherboard stably in high-load multi-core scenarios.

The NZXT Z790 supports Intel LGA 1700 pin processors, including Intel 12th/13th Core i9/i7/i5/i3, Pentium, and Celeron processors. The official N7 Z790 CPU Support List is available on the website, but both N7 Z690/Z790 motherboards can support Intel 12th/13th processors. This means that if players already own N7/N5 Z690 motherboards and want to upgrade to Intel 13th processors, there’s no need to buy a new motherboard.

NZXT had also launched the N7 Z690 motherboard during the Z690 chipset, but it only supports the previous DDR4 memory generation. In contrast, the N7 Z790 supports the latest DDR5 memory. As DDR5 memory prices become increasingly affordable, upgrading to the DDR5 memory platform is a good time.

The N7 Z790 features four DDR5 DIMM single-side snap-in memory slots, supporting a total of four DDR5 memories with a maximum capacity of 128GB, or 32GB per memory slot. The memory overclocking frequency is advertised as up to 6000+ MT/s (based on the official memory QVL table) and is Intel XMP 3.0 certified for one-key overclocking.

It’s recommended to install the 2 DIMMs dual-channel memory set, which is commonly purchased when ordering, in the A2 and B2 slots (the second and fourth slots from the left). Installing the two memories in these positions can allow the memory to operate at higher frequencies more easily.

Four-slot single-clip DDR5 memory slot supports 128GB memory expansion and XMP 3.0.

The right half of the motherboard is arranged in a clean and orderly manner, with the remaining small slots of NZXT moved to other positions. On the right side of the motherboard, there are only two slots: the 24-Pin power supply slot and a front Type-C USB 3.2 Gen2x2 (20Gb/s) slot. It also has one USB 3.2 Gen1 slot that supports two front USB 3.2 Gen1 ports and four SATA3 6Gb/s slots.

The N7 Z790 motherboard has three M2 PCIe Gen4 x4 SSD expansion slots, which is the same as the Z690 model. All three slots support PCIe Gen4x4 2242/2260/2280 specification NVME M.2 SSD installation, and the M2_2 slot can accommodate a longer 22110 size. If a player has an early M.2 SATA SSD for expansion, it must be installed in the M2_3 slot.

Each of the three M.2 SSD installation positions has a white decorative cover on top. The upper cover is magnetically fixed with a strong magnet but has no heat conduction effect. Only the first M2_1 slot is visible after removing the white decorative cover, which has a heat sink with a thermal pad to help dissipate heat from the M.2 SSD.

After removing the magnetic white decorative cover, you will find that there is a heat sink fixed above the M2_1 socket.
