When power cuts off, browns out, or fluctuates outside safe levels, a UPS instantly provides clean battery backup power and surge protection for any sensitive electronic equipment plugged into the device. A UPS is part of computer backup power supplies — such as these leading options — that are necessary to ensure your PC isn’t damaged and files aren’t lost due to electrical issues.
