Benchmark Reviews published a review on the OCZ ModXStream 780W Modular PSU OCZ780MXS

The OCZ ModXStream Series is a new line of power supplies designed to offer consumers a combination of OCZ's legendary PSU architecture and an effective modular cable management system. Available in 780W and 900W models, the ModXStream offers power solutions to gamers on a budget, and hardware enthusiasts alike.  The ModXStream was engineered to be the quietest PSU available so gamers can hear their games and not their PC.  The load-controlled 120mm cooling fan helps keep the unit operating efficiently, but Benchmark Reviews knows that there is more that meet the eye with each and every power supply.  Load testing for AC ripple and DC power regulation will prove if the OCZ ModXStream 780W Modular PSU OCZ780MXS is as good as it looks.
