THE PG Z790I LIGHTNING WIFI

The PG Z790I Lightning WiFi is a mini-ITX board that basically measures 17cm in width and 17cm in length.

ASRock has placed sufficient weight in MOSFET/VRM cooling which is always a nice thing to see.

By using just 2 DIMM slots the Z790I Lightning WiFi can reach DDR5 speeds of up to 8600MHz and above.

The 3 SATA 600 ports should be plenty, especially for a mini-ITX build.

A single PCIe 5.0 x16 slot is located just under the primary PCIe 4.0 Gen4 socket (the M.2 armor heatspreader should suffice for a Gen4 SSD).

Taking a look at the rear I/O we find the 4 USB 3.2 Type-A Gen1 ports, two Antenna connectors, DP 1.4 DSC port, HDMI 2.1 TMDS port, 2.5G RTL8125BG port, USB 3.2 Type-A Gen2 port, USB 3.2 Type-C Gen2 port and the audio ports (SPDIF/2x3.5mm).

What stands out at the bottom (aside the aluminum pieces) is the 2nd PCIe 4.0 Gen4 SSD socket.

For this review I'll be using the Fury Renegade Limited Edition 48GB 8GHz CL36 dual-channel kit by Kingston and the Core i9-13900K by Intel (same CPU I've used with past Z790 reviews).
