Hello, i don't have much knowledge on UPS's so i thought it would be easier making a topic. How many VA and Watts does my ups need to have to support my pc? Specs: MSI GTX980 GAMING 4G i5 4690 8GB Ram Corsair CS650M PSU My previous UPS works when my pc is at idle, but when im gaming it doesnt work and just shuts down everything. Note: i only need the UPS to last 5mins or so when there are electricity shutdowns.
