This is an audio amplifier that fits perfectly in a 5-inch bay of a PC case. I am selling it because I removed it due to a change in my PC system and no longer need it. It was working normally until I removed it. I don't think this amplifier is genuine, but I will include the power cord. I have been using it with this power cord. It's an old item, so please purchase it if you understand this. No returns or refunds, please.
