Just went on the Be quiet website and I want to upgrade my old Be Quiet! CM BQT L8-730W Pure Power 80 Bronze (is this a Pure Power 8 Model?) to a Straight Power 11 750W. I selected what I assumed to be my old PSU on the website (Pure Power 8) to check if I need cables and it came up with... Drives Tick PCI-E Cross P4/8 Cross 24-PIN Cross. I am thinking of getting somebody to upgrade for me as I am not good with the hardware side of things. I have ordered the new PSU though.
