What make and model is the PSU? Consider 18Amps per card and 10-12 for your processor on the 12V rail. A good available 50Amps on this rail will get you there. A corsair 650tx fills the bill nicely. | Report abuse Ask the community Publish Tom's Hardware>Forum>Graphics & Displays>Recommended minimum psu for crossfire ati 5870 2gb> Related ressources: Forum850w PSU enough for Crossfire 2gb 5870 s eyefinity 6 editions ForumATI 5870 Give Away - Winner just confirmed:) Hope you had fun!
