ASUS ROG Strix Z490-I Gaming Motherboard Overview

The Z490 chipset is perhaps the biggest jump that Intel made so far over the Z390 chipset. For starters, the Z490 features Intel’s LGA 1200 socket for the 10th generation Corner Lake-S processors.

Now the board we’ve got here is the ASUS ROG Strix Z490-I Gaming. This is one of the higher end Z490 chipset based ITX motherboards from ASUS, aimed directly at the SFF enthusiasts. It comes with almost everything the full Z490 chipset has to offer, with the constraints and limitations of the ITX form factor. Without further ado, let us check this board out.

Design, Build and Connectivity

The ROG Strix Z490-I Gaming follows the recent trend with ASUS’ ITX products – which is the inclusion of a daughterboard together an enclosed back panel area with an integrated I/O shield. This is a really clean looking motherboard that exudes a premium aura wherever you look at it. Layout in general is well organized. Everything you need to see at the edge are located at the edges of the board. All headers and or ports that needs to be together are grouped as well.

Behind the board lies an excellent solder job. We could also clearly see the VRM components here. No M.2 port here though, in contrast to the older ROG Strix models. Everything is just laid at the front.

Top most part of the board has two fan headers and the 4-pin AURA header. We also got an updated 4+4-pin power connector here that ASUS dubs as the PowerCool II socket. It’s basically a reinforced CPU power header with tighter than recommend specifications.

The motherboard is built for SFF systems, but ASUS still managed to pack an 8+2 power phase design for overclocking. ASUS also improved the VRM cooling with an included 40mm fan and a unified heatsink for the chipset and VRM. The heatsink itself acts as the backpanel IO cover.

The right side of the board houses the usual headers for power, storage and connectivity. From top to bottom, we have the USB 2.0, USB 3.2 Gen1, USB 3.0 Gen2 and the SATA ports. We also have the Clear CMOS and the T-Sensor header here as well. Both these headers would be a pain in the ass to use with a PCIe card in place so make sure to prepare ahead. As for the memory, ASUS specified a maximum capacity and frequency for the DRAM at 64 GB and 4800 MHz respectively. That frequency support is a courtesy of the OptiMem II technology, improving trace layout to significantly enhance memory stability and compatibility.

Now the daughterboard is one of the main highlights of the Z490-I Gaming. It is basically a 3-in-1 board with dual M.2 slots mixed to the SupremeFX S1220A audio solution. The PCH is just below this one, sharing the same cooling solution with the rest. Sadly, PCIe support is still 3.0 x4.

The bottom most area features the PCIe 3.0 x16 slot that’s probably the only downside of the board since we’re expecting full PCIe 4.0 support for future CPUs. In spite of this, PCIe bifurcation is supported so you could run expansion cards at x16, x8 + x8 and so on compatible storage expansion cards at x8 + x4 + x4 and x4 + x4 for RAID. Still, we prefer PCIe 4.0 support for maximum bandwidth allowance for this feature. The front panel and extra fan header is located on this area as well.

Back panel options are not bad. We have four USB 3.2 Gen2 here, together with the usual assortment of display ports. We also have a BIOS FlashBack button here with a matching UEFI update capable USB port. According to ASUS, there’s no need for a CPU and memory for the update to work.

Final Thoughts

In conclusion, the ASUS ROG Strix Z490-I Gaming is a highly capable ITX motherboard designed for small form factor (SFF) enthusiasts. Its thoughtful design and robust build quality reflect ASUS’s attention to detail, especially with the inclusion of the innovative daughterboard that consolidates M.2 slots and the SupremeFX S1220A audio solution.

The motherboard’s cooling solutions, reinforced power connectors, and comprehensive I/O options highlight its suitability for overclocking and high-performance tasks.

However, despite its strengths, the lack of PCIe 4.0 support is a notable drawback, especially given the premium price of Z490 boards.

For users with older platforms, the upgrade might not provide significant benefits unless they seek to leverage Intel’s latest CPUs. For those requiring PCIe 4.0 capabilities, the ASUS X570-I Gaming platform remains a preferable alternative.

Ultimately, while the Z490-I Gaming excels in many areas, its value proposition depends on specific user needs and system compatibility.
