I have a second PC, hooked up to a 650VA UPS. I recently upgraded its graphics card from a Radeon HD6850 to a Geforce GTX580. When I updated the Windows Experience Index thingy, the UPS started beeping like crazy, as if it had switched over to battery backup.
It seems to run fine, until I do anything graphics intensive like playing a game.
Is the PC itself trying to draw too much power for the UPS to handle? I was under the impression that my 650W power supply COULDN'T pull more than 650W, or is it just that it wasn't drawing a full load before the upgrade, and a 650VA UPS cannot handle 650W of power consumption?
Any advice would be greatly appreciated.
