Power requirements for graphics cards

As so many people aren't sure how much power a modern graphics card requires

MINIMUM

, I've decided to write a list of various models with the sort of PSU they require. Obviously it would be better to get something better than what is stated. It is only a rough guide, as it also depends what other hardware you have in your system. I hope it is of some use to people.









The following are the minimum power requirements using a PSU with a single +12V rail. Also these requirements are for a system containing basic components (unless otherwise noted). The more add in cards and hard drives that a system has, the more amperage draw on the 12v rail.





This list is legacy and not updated. For modern vgas check Flobelix's Power requirements for graphics cards 2.0
