What the Experts are Saying...
"In terms of performance Corsair continues to exceed our expectations with their Professional Gold Series. Corsairs exceptional range of power supplies just received another fantastic model and it appears they really can do no wrong in the PSU market." - HardwareHeaven August 19, 2010
"Computer power supplies have come a long way in just the last couple of years. With the implementation of resonant mode topologies and DC to DC converters for non-primary DC output, we've seen efficiency increase more and more. The AX850 is an example of how to implement these features as effectively as possible by avoiding the high ripple typically associated with resonant mode topology and the poor voltage regulation typically associated with DC to DC converters under load." - JonnyGuru August 26, 2010
"How best to put this......the Corsair AX850 is an outstanding entry into the 850W segment that's only real competition, that we have reviewed and is readily available at this time, is the Corsair HX850. The single best, and most distinctive, feature of the AX850 is not its efficiency as the unit's marketing and color scheme may indicate, but rather the unit's amazing DC Output Quality." - HardOCP October 7, 2010
