ASRock Z790 PG-ITX/TB4 Overview
This is of course a small board, for those who aren’t familiar Mini-ITX boards are only 12 inches by 12 inches. Like most Phantom Gaming boards from ASRock this board has a black and red design with some silver accents as well.
Starting at the CPU socket we have Intel’s LGA 1700 socket which supports Intel’s 12th, 13th, and 14th generation Core processors.
Surrounding the CPU socket we have our power delivery components and ASRock is making use of a 10+1+1 power phase design with 105A smart power stages. So with 10 phases for the CPU, you have 1050A of power available. The power delivery components are covered by two large heatsinks which are connected by a heatpipe. On the top of the larger heatsink is a rear I/O cover, which brings the top-half of the board together and looks quite nice too.
Hiding in the top corner of the board is your 8-pin EPS connector. Moving across the top-edge of the board you’ll find a 3-pin addressable RGB header and three 4-pin fan headers, one of which is your CPU fan header.
Since this is a Mini-ITX board you are only going to find two DDR5 slots. These slots are metal reinforced and support DDR5 memory up to 7000 MHz. Along the front-edge of the board you’ll find your status LED array, clear CMOS button, 24-pin ATX power connection, front panel header, 4-pin standard RGB header, USB 3.2 header, three SATA ports, and a USB 3.2 Gen 2×2 header.
Since this is a Mini-ITX board we have just a single PCI-Express 5.0 x16 slot. It is metal reinforced, which is definitely nice to see. Right above this slot is a heatsink, which covers the main M.2 slot. This slot is PCI-Express 4.0.
Moving along to the rear I/O we have an integrated I/O shield that has the Phantom Gaming logo on it. As far as connections go from left to right we have DisplayPort, HDMI, six USB 3.2 gen 2 Type-A ports, 2.5G LAN, two Thunderbolt 4 Type-C ports, WiFi 6E antenna connections, and your audio connections. ASRock is using Killer for its networking so the 2.5G LAN connection is the E3100 while the WiFi 6E is their AX1675.
Flipping the board over you’ll actually find two more M.2 slots. Both are PCI-Express 4.0, but one will also support SATA-based M.2 drives as well. These do not come with heatsinks.
