The PG ITX is a good-looking board, primarily black in appearance with subtle notes of red. This will push you towards a black and red-themed build for those going that route. Otherwise, the single PCIe x16 slot is shielded and reinforced, and the 10 phases VRM is cooled and covered by integrated heat sinks.

Power, Thermals and Final Thoughts

Power Consumption

ASRock Z590 Phantom Gaming ITX/TB4 Motherboard Review 56 | TweakTown.com

Wrapping up testing, we saw a system power draw of 138 watts idle, 481 watts full load with R23.

Thermals

ASRock Z590 Phantom Gaming ITX/TB4 Motherboard Review 57 | TweakTown.com

Temperatures during testing reached a peak of 65c while idle was at 23c.

Final Thoughts

The PG ITX/TB4 is our first look at an SFF Z590 motherboard, and ASRock has done a rather nice job in the design and build of this platform. First, it's one of the only ITX boards to offer Thunderbolt 4, and it may be the only board, at least on the surface, to be advertising 40Gb/s compatibility with the USB 4.0 specification too.

In addition, this board offers a solid enough power design to offer modest overclocking for 11th Gen Intel CPUs though I wouldn't expect any WR from it. Additionally, we have support for multiple NVMe, one being Gen4, a secondary on the rear of the board for Gen3 while keeping a full-size PCIe x16 slot, again at Gen 4.

Connectivity has been boosted with a full complement of USB 3.2 connections alongside Intels Killer Networking brand that supplies a fantastic set of NICs that include the E3100G and AX1675x; this offers potential gamers Killer Control Center which in turn presents more control of your network with Doubleshot Pro, Xtend and QoS technologies.

What We Like

Connectivity Connectivity includes nearly every available standard.

Price MSRP at $289 makes this one of the lowest cost Z590 ITX platforms.
