Difference between Crossfire Ready and Certified?

[Commander FAT]

Some power supplies on Newegg are listed as Crossfire Ready and some are Crossfire Certified. What's the difference? Is a Crossfire Certified power supply absolutely necessary to do Crossfire?

I don't know what the difference is, but I can tell you that the ratings are largely insignificant. You should base your PSU decisions on what is a quality unit and what isn't, rather than what has Crossfire or SLI certification and what does not. There are many PSUs out there that are not certified for Crossfire or SLI but are still perfectly capable of handling a multi-GPU setup. There is also the fact that ATI and nVidia will not give their multi-GPU certification to a PSU model with the other's certification, so although any good SLI-certified PSU can run a reasonable Crossfire setup and vice versa, you will never see a PSU that is certified for both.

As Zero82z said, much of it is marketing. Go with the specs and decide for yourself.
