I have a Seasonic MKII Bronze 650W PSU. I recently got a new graphics card that requires I use two 6+2 PCI express power cables. The problem is that the MKII only comes with a single 6-8 pin cable, so I'm going to need another one in order to use my new graphics card. I could use a 6-to-8 pin adapter, but I'd prefer not to for aesthetic reasons. For the life of me I can't find anywhere that sells just straight 6-8 pin cables. Anyone know where I might be able to buy one?
