I see alot of them advertised. however, when I look at the specs they list 3) 6 pin and 3) 8, or 6+2 pin pci-e connectors. this will not run 4 video cards that take one of each connector. so what PSU's do actually have the needed 8 pci-e connectors? preferably 80+ certified. modular is also a plus but not a requirement.
