i have a seasonic x-850, and am planning on installing a second gtx 780 in sli, but cannot find my other pci-e modular cables. what should i do? i also have an hx 650 modular power supply, can i use the pci-e cables from there?
yup daisy chain that old psu and reduce the load on main just google what wires to power on second psu ,if you good with splicing you can wire it to boot up with power switch
