Madshrimps posted a review on the Spire RocKeteer IV 600W SLI Ready Power Supply

This 600W SLI ready unit from Spire features a low noise 120mm fan and enough power to run the most demanding gamer setup; being sold at a very competitive price of <$70 we find out if it=B4s up to a Crossfire challenge.
