Review: Everything Just Works - I usually get the less-featured asus board and have for years. I read reviews on this one and folks said it wouldn't run memory at 6000. It's running my expo ram at 6000 cl30 just fine. I put a 7950X in it. No issues there either. The bios let me set the TDP so I dropped it to 120W. It was nice to have a granular setting for this and not a stupid "eco mode" setting. Phoronix unigine-heaven says I'm tied for the best result with my video card (7900XT) at 2K. You really can't ask for anything more than that on a system with reduced TDP. Nothing gets hot. The onboard RGB was picked up by Linux just fine and worked with OpenRGB. I don't use the wifi or blutooth but I'm sure they are fine. Plenty of room for a huge Noctua cpu cooler. Benchmarks are fantastic. I didn't even have to update the bios. It had the most recent. The only thing I had to do in bios after turning off wifi and blutooth and setting TDP was turn on Resize Bar. For some reason it wasn't on by default. Oh, and I had to turn on EXPO for my ram. But that was it. Boom, saw the ram, overclocked it. Rarely do I build a system and it's just working the first time I hit the power button. That's how it was this time. Save your money on an AM5 build. Use this board.

### ⭐ Costly RMA process, two of two boards purchased had failed in less than 3 years
*by J***E on March 19, 2025*

Bought two of these boards from two different sellers over a years' time, both failed. The first board lasted less than a month and fried my Seasonic power supply with it. The second board lasted just under 2.5 years but was not used daily, took it to the local Micro Center who confirmed it was dead $80 later and refused to assist with RMA (thought they were a licensed Asus technician?). The first board's RMA was denied after one of the pins was bent in transit. Asus has you pay the shipping cost of RMA. Given how much the price has gone down, I think I'm ready to cut my losses and move on to a different brand, no more Asus for me!
