I have a gaming PC that is powered by a 450 Watt PSU and I want to know if there is a way to also power my PC with like a battery because where I like there has been a lot of snow storms and the power has been going out. Any info would help!
The power of the PSU isn't that important; what you need to determine is how much power the system, including the monitor and other accessories, requires. How long does it need to be powered up if there's a power outage? That will determine the size of the UPS. You can use a PSU calculator to determine your system's power requirements.
