The pinouts for the 4 adhere to Intel's standard for front panel connectors, and are probably the same as your old mobo. It's the same on almost every mobo. From the leftmost pins filling in the 4 pins each in top and bottom row: +PLED- PWR_SW +HDD_LED- RESET_SW More on reddit.com

Had the same issue in 2024 with my Prime B550M-A WIFI II but noticed seperately and didnt use the shitty asus armory software The Realtek 8852BE WLAN driver is the correct one and does not show on the Asus page. I got it from here: https://support.lenovo.com/de/de/downloads/ds558080-realtek-8852be-wlan-driver-for-windows-11-64-bit-version-21h2-or-later-ideacentre-3-07ach7 The "Realtek Bluetooth Driver V1.9.1051.3002 for Windows 10 64-bit& Win11 64-bit---(WHQL)." option under bluetooth on the asus driver page fixed the bluetooth for me. Annoyingly windows kept insisting my bluetooth works and simply doesnt detect any devices but this driver fixed it instantly (from here: https://www.asus.com/motherboards-components/motherboards/prime/prime-b550m-a-wifi-ii/helpdesk_download?model2Name=PRIME-B550M-A-WIFI-II ) More on reddit.com

Both are near equivalent in performance. If the same price, prob go with the MSI since has better reviews. Both have WiFi 6, and B550 features. The MSI has a front USB C port if needing that for the case, and has a M.2 heatsink if going to be using high performance SSD. If using a MicroATX case, the GPU slot sits lower on the Asus so the GPU will be lower to the bottom starting on the 2nd slot down on the back of the case, whereas on the MSI it sits higher in the first slot on the back of the case. The main difference out of the box, is that the Asus will support 5000 series CPUs right away, while the MSI might need a BIOS update. However, the MSI does have a BIOS flash button 'M-flash' to update the BIOS by USB drive, so won't need an older CPU to perform the update. Will just need another computer to prepare a USB drive with the BIOS update. Also, is this a new build? Any thoughts of going AM5 AMD instead of AM4 to have a better upgrade path in the years ahead? AMD just announced today at Computex AM5 support through 2027. More on reddit.com

Those are your front panel connections. Power and reset switch, power and HDD leds, motherboard speaker, etc. See page 1-5 of your manual for how to connect.
