2025 | Affordable ITX Mobo

By Daniella
Rated 5 out of 5
Date: 2025-02-08

A couple of months in: This ITX motherboard initially stood out to me for its affordability compared to similar ITX boards. The key piece being that I wanted to downsize my ATX PC build to an ITX build, so it was great considering it's compatibility with my existing CPU, GPU, RAM, and storage. Key Features: -- Compact Size: The ITX form factor had no issues with my ITX build in mind (NR200 case + 3080 GPU). -- Compatibility: Worked seamlessly with older components, so the cost of buying an NR200Max, for instance, was actually more expensive than buying this ITX mobo, a new PSU, a new case, and a new cooler. -- Affordability: Offered great value for money compared to other motherboards in the market that I had seen. -- Performance: While it may not rival my previous X570 ATX board, this motherboard has so far delivered great performance for casual gaming, daily productivity, etc. TLDR Pros: ----Compact and space-saving ----Affordable price for an ITX motherboard ----Reliable performance for casual gaming TLDR Cons: ---- None that I've found so far! Verdict: For anyone looking to downsize their PC build without sacrificing performance, the Gigabyte AORUS ITX motherboard is a stellar choice. It offers a balanced blend of affordability, compatibility, and practicality. I highly recommend it to casual gamers and especially for those wanting to keep their AM4-generation components such as CPU, GPU, Storage, and RAM in a smaller form factor.

Great little board!

Does using an NVME M.2 drive in either or both M.2 slots of this motherboard leech PCI-E lanes from the x16 slot? My current motherboard cuts PCI-E lanes for my GPU down to x8 while using an NVME drive and I'm looking to avoid that situation.
Asked by: Justin
Ryzen 3000 chips have 24 PCIe lanes. 4x for the chipset (running at gen3 speed) 4x for the front M.2 slot (the other M.2 is connected via the chipset) 16x for the main PCIe slot no other direct PCIe devices to worry about
