I was pleased to see that the Miniplant came with a 3-year warranty, which adds a certain amount of value to the unit. The Miniplant comes with a very large price tag that could be hard to justify, however this power supply was able to deliver decent performance for what I could test with. When added in with the warranty I believe that it would be worth the price. As for SLI Ready I could not located this PSU anywhere on Nvidia's site as a recommended PSU for SLI setups.
