## Description

Buy

Review: Still an excellent AM4 board, even if the price isn't what it used to be - I've been using this motherboard for quite a while now and it's continued to perform flawlessly. Setup was straightforward, stability has been excellent and it's handled everything I've asked of it without giving me any reason to think about replacing it. The board offers a strong feature set for AM4 systems with plenty of connectivity, good build quality and enough expansion options for the vast majority of gaming and productivity builds. It also happens to be one of the better looking AM4 motherboards in my opinion, especially for lighter themed builds. The only thing that surprised me when looking at it recently was the price. It seems noticeably more expensive than when I originally bought mine, which makes it a little harder to recommend at current prices than it was a few years ago. As with DDR4 memory, part of that comes down to the industry gradually moving away from AM4 and DDR4 production towards newer platforms and AI-focused hardware, which has made some older but still popular components hold their value far better than many people expected. Overall, it's been an excellent motherboard and I'd happily keep using it for years yet, although new builders should compare current pricing against entry-level AM5 options before committing to a fresh AM4 build.
Review: Good thermals, nice lookin board too - Just a really nice motherboard with neat features. Bios flashback is super handy to have and the two thermal pads on the m.2 heat sinks are such a nice addition. Just be careful because if you use both of those slots it takes up 2 of your 6 sata ports rendering 2 of them useless. Should be alright though. Otherwise phenomenal board
