I rencently bought an ATI Radeon 6850 that is rated for 500W PSU. I know I should have at least a 500W PSU, however, I am trying to recycle some parts from an old computer and have a 420W power supply which would be only 80W from the recommended PSU.
Could I run the video card reliably my 420W power supply or is the 80W just to big of a difference.
This person said they're running the card on a 350W PSU
This post says the card draws 150W at load
