## Customer Reviews

### ⭐⭐⭐⭐⭐ All-around good motherboard
*by R***T on May 25, 2025*

Awesome for the price I paid $150 and this Motherboard has features of a $250 motherboard and it’s AM5 so it supports all of the new chips. And it runs 2500 MB bandwidth . it looks good in black or white cases. It has two M.2 slots and comes with a cover for one of them to Better help the heat transfer. I love how it gives you an app to update all of your drivers. You don’t have to go searching for it.

### ⭐⭐⭐⭐⭐ High quality
*by J***A on June 11, 2025*

"This motherboard is rock-solid! Setup was straightforward, and it has all the features I need for a smooth and powerful build. The BIOS is user-friendly, and everything runs like a dream. Highly recommended for any PC build!"

### ⭐ Is the problem a malfunction, a bug... or a feature?
*by M***W on April 11, 2024*

My old computer, which I purchased in 2012 was getting past it. So I decide to build a new system, being a 90's era Windows fanboy building a PC is a piece of cake. Normally.I selected this Asus board, the Ax2 version for the build, the reviews seemed good. I was careful to select the m.2, ram and CPU from the approved list.When I installed the board and components a couple of problems became quickly evident.The Sata SSD drive that my OS was on could not be recognized in the bios, they would appear on a list of connected devices... but they would not appear on the boot list. I say they because I also tried an older spare drive.While problem solving this a second problem became evident... my fan wasn’t working and the CPU temp reached just over 90C very quickly.I tried another spare fan and both CPU headers were non functional. However as a workaround I was able to connect my Cooler Master fan to another fan header.So I tried to call ASUS... they don't support motherboards over the phone. Period. I was turned away. Let that sink in people... you won’t get anywhere near someone you can verify as human.I tried the ASUS online chat, the support person told me that I would have to sign up for something called Just Answers to get support.Now I was frustrated when I did this and I did not read the fine print, I thought I was paying a token $2 fee. However the two dollar fee was a sign-up fee. I was also charged $70 for a couple of copy paste answers to the problem.To be clear I did try everything on the list of things to try. Some I couldn’t do however because there are settings that you can select in the bios to get it to recognize the drives... however all of those settings were grayed out, such as CSM. Even a bios update did nothing.I decided to buy a device that holds the m.2 and plugs into the USB... using a different computer I cloned my OS onto the new m.2 drive. Even that didn’t work in either slot, I couldn’t get it to recognize any drive at all.Now while I was problem solving this I found a video on YouTube that said with this board...“Ïf CSM item is not user-configurable and shows in grey, please install an add-on Graphics card and CSM item will turn configurable”To be clear... I did carefully choose the CPU based on the fact that it DID have onboard graphics, and I did have a couple of graphics cards on hand however I did some digging and found that neither of my cards were good enough, apparently “you need a dedicated video card that supports VBIOS”Now nobody from ASUS... not even the guy who took 70 bucks from me for a minutes work. None of them told me that. They had led me round in circles.This is unacceptable, expecting someone to have to buy a high priced graphics card just to make a motherboard work. Disgusting.Now I have returned the board, I will never buy ASUS again. Ever.Update 22nd April...I have replaced the Asus board with a cheaper Asrock board, the B650M PG Lightning Wifi. Thus far it is working well and has no coil whine.However when I went to select CSM I was able to select it, however when I exited BIOS it would restart and default back to CSM being off. But at least I was able to select CSM which told me it was working unlike the Asus board which support couldn't tell me if it was working or not. Who knows?So this lead me to do some research as to why my drive wasn't being recognized, it turns out for the last few years legacy support for old hard drive formats has been removed.Now what is shocking is how no one told me this. I contacted Asus several times and even paid the 70 bucks for third party support, they all knew I was using an old SSD and none of them said... "Hey Matt... the reason you can't use you existing drive is because it needs reformatting, there is a free Windows utility that does it, all you have to do is google "Convert an existing Windows 10 Installation from Legacy BIOS to UEFI" and follow the simple instructions"To be clear NO ONE told me that, even the troubleshooting video on YouTube mentioned nothing.So Asus still gets an F for their support for telling me nothing that I needed to know and only some things that I didn't need to know.
