I bought an EVGA 1000P Power Supply (PN 220-PS-1000) not knowing it was an older model. I can't find any information in regards to cables. It works fine, but I need another pair of 8 pin cables for powering a second EVGA 3080 TI hybrid GPU. I have tried reaching out to support and everything forces you back through a support ticket. In an attempt to register the product I get the message "Serial Number is not related to the part number." In that case I can't get any help through the EVGA support system. Can anyone help me out in regards to which cables will work for this power supply so that I don't burn anything up? Thank you for the help.
