This power supply is used but in good working condition. I am only selling because I upgraded my system and needed more wattage. I do not have the original box because it came as part of a Cyberpower PC prebuilt system.---------------------This EVGA 450W BV power supply is a reliable and efficient choice for your computer. It has a maximum power output of 450W and is designed to fit ATX form factor. The cooling system includes one fan to keep your computer running smoothly. This power module is modular and comes with 24-pin connectors. The model is EVGA 450 BV, and it is a great choice for those looking for a high-quality power supply.
