Phoronix posted a review on the Hiper Type-M 780W PSU

Back in 2005 we had looked at the Hiper Type-R Modular 580W power supply. This was a unique power supply that had a modular cable design and had performed very well. Even the Type-R's packaging was unique, with the power supply arriving in a plastic toolbox. We haven't looked at a Hiper power supply now in almost three years, but today we are looking at the Type-M 780W from Hiper Group. This power supply is dual-GPU ready (including compatibility with PCI-E 8-pin connectors), utilizes active PFC, and has four +12V rails.
