OCC has published a new review on the Corsair HX750W Power Supply

The Corsair HX750W is an 80 Plus Silver certified power supply and the figures obtained during testing confirmed this with the efficiency peaking at a massive 90% on 230VAC. Combine the excellent efficiency with top notch DC voltage load regulation and low ripple/noise on all the rails, and the Corsair HX750W is up there with the best. The box lid carries the Nvidia SLI Ready logo, but I wasn't able to confirm this on the Nvidia SLI website, so perhaps it will appear in the next update. The Corsair HX750W has four 6+2-pin PCI-E connectors, making it the ideal power supply for any high end SLI or Crossfire configuration, especially when you consider it delivered 50A on the 12V rail with very low noise.
