Mainstream Phantom Gaming! Z790 Nova WiFi Unboxing/Super Crazy 6 M.2 and Tool-Free Design

Outside of the i7-14700K which boasts core enhancements, the 14th generation Intel Core processors mainly exhibit increased power consumption. Thankfully, they maintain compatibility with the LGA 1700 socket. This compatibility ensures that motherboards with chipsets like the Z790 and B760 remain relevant. In light of this, ASRock has rolled out a slew of Phantom Gaming motherboards, as well as updates to the Taichi Lite series.

The Z790 Nova WiFi is versatile, supporting Intel Core processors from the 12th to 14th generations. It comes equipped with a 20-phase 90A SPS power unit and offers four DDR5 DIMM slots, accommodating up to 192GB of RAM, with overclocking speeds reaching 7800MHz. For visual outputs, it integrates HDMI 2.1 and DisplayPort 1.4 DSC.

On the expansion front, the board features a PCIe 5.0 x16 slot, along with PCIe 4.0 x4 and PCIe 3.0 x1 slots. A standout feature is its impressive six M.2 expansion slots. The primary Blazing M2_1 slot, which is routed through the CPU, supports PCIe 5.0 x4 SSDs. However, equipping an SSD here limits the bandwidth of the subsequent PCIe slot to x8. The secondary Hyper M2_2 leverages an additional PCIe 4.0 x4 CPU lane.

The subsequent M.2 slots (Hyper M2_3 to M2_6) all accommodate PCIe 4.0 x4 SSDs, although the SATA count is trimmed to four. Network capabilities include a Dragon RTL8125BG 2.5GbE LAN, accompanied by the latest Wi-Fi 7 802.11be 2×2 and BT 5.4 wireless connectivity. Audio is managed by a Realtek ALC4082 7.1ch codec, supplemented by Nahimic Audio software.

In terms of USB ports, the motherboard provides a pair of USB 3.2 Gen 2×2 Type C in a side-by-side arrangement, alongside various other USB ports. The highlight remains the expansive M.2 storage configuration, ensuring versatility for multiple computing needs.
