Not very well versed on UPS, but the house I live in currently has some power issues where it'll sometimes go out 2-3 times a week or more, never for more than 3-5 minutes max, my system is custom built but I am drawing about 250-300 watts max with my hardware (i3 6100, 2x 8GB DDR4, 2x SATA hdd, 1x sata ssd, gtx 950) running on a 450 watt PSU, trying to find something that can run it for at least 3 minutes on a power blip and help prevent damage to my system, but not sure what to look for, also trying to not break the bank on it if at all possible.
