Absolutely Thrilled with My New Motherboard
Motherboard has exceeded all my expectations! From the moment I unboxed it, I could tell this was a high-quality component. The build quality is exceptional, with a sleek design that fit perfectly into my case. Features: The array of features is fantastic. The dual M.2 slots provide incredibly-fast storage options, and the support for multiple GPUs/nvidia sli is rather handy for some people. The BIOS is user-friendly and makes tweaking settings easy. Additionally, the built-in RGB lighting adds a nice touch to my build, making it that little bit nicer I never find myself short of connections due to the array of ports and a very modern io For all the features and performance it offers, this motherboard is worth every penny. It's an investment in quality and reliability that has significantly improved my pcs looks and performance! If you're looking for a top-tier motherboard that combines power, features, and style, look no further than the ASUS Prime X299-A II.

Defective motherboard
Unfortunately, the motherboard I received was defective, with the error "USB over current detected" being report by BIOS, with no USB device connected to the motherboard. I suspect this may have been used before I received it. Not a happy customer.
