★★★★★Open Box Excellent Condition Should Mean Working
I purchased this ASUS motherboard as an open-box item in "Excellent Condition." When the box arrived, all components were inside and physically looked clean. However, once I started building, the board showed no signs of life. I tested everything outside the case using a screwdriver to jump the power pins. CPU fan spun, power supply turned on, but there were no debug LEDs on the motherboard, nothing at all. I tested with known working RAM, CPU, and GPU. No image, no POST, no power indicators. After thorough troubleshooting, I confirmed the motherboard itself was dead. This is not a review against ASUS, the board may be great when functional. This is about Best Buy's open-box grading. "Excellent Condition" should mean the product is fully functional, not just cosmetically clean. If you buy this open-box, test it immediately within the return window. I had to return mine and buy new.

★★★★★Great Motherboard, Needs Better Software Support
This mobo really is a great match for my AMD Ryzen and RTX 5080 card. It supports a lot of overclocking features and very fast bus. The BIOS features are good but not great. The OC UI ranges from basic to advanced. Not much in between. Could use more descriptors of each setting at this point for novices like me dipping into OC'ing. The software Ai Suite 3 for Windows is a bit too basic. It locks out many controls, and doesn't like to remember settings. I guess the physical board is great as you expect from the TUF line. The ASUS software on and off board are lacking.
