OCZ EvoStream 600W
 

The OCZ EvoStream 600W is a powerful PSU that comes with modular connectors to help you reduce the cable mess in your case. On top of that you get four independent 12V rails that can supply all the power your video cards may ever need. In our testing on a Crossfire system the 12V line was exceptionally stable, making this unit a great choice for overclockers.
