i bought a UPS that provides a max 255watt draw and it completely failed me. The reason i need a UPS is because i live in the sticks and i get a extremely fluctuating power supply in my home. My current config has a PSU that provides 750watt and my current setup only draws a max of 372 watts. I may be provided with a gtx295 gc which will increase my draw to 615watts. So here is my problem, do i need a UPS that provides greater battery protected supply then the actual wattage that i need for that half second.
