I am upgrading my GPU to a 380x Nitro 4gb and I need a new psu preferably 600W. My current system specs are in the signature. Also will 600W be a overkill? Budget is around 6000INR(indian currency)
800VA means 800W without powerfactorcorrection.
So yeah it should work with a proper 800W UPS, I think. The system will probably use 300-400 Watt at full load, so a 520W single rail psu (like the Seasonic S12II or M12II) will be great as well!
