I recently bought a open box asus z270 rog maximus hero ix. not only was the motherboard missing accessories it was also missing the rear armor shield that protects the audio this part is supposed to be screwed on or welded on. all I know that its not a accesorie its a part of the motherboard . because I'm always get q codes and audio error messages and some of the usb ports don't work and I cant install or uninstall drivers and the performance on this motherboard sucks. my cpu temps are threw the roof on the lower spec msi z270 a pro motherboard I had before getting this one would do 4.8 easy I cant get the cpu past 4.5 on this motherboard and I bought it from newegg. and I explained what they did and they do not want to help me
