I recently learned that certain GPUs should have two separate PCI-E cables plugged into them instead of one with a splitter. As one cable is not rated to provide the power that the GPU tries to draw into it.  I understand that this isn't always an issue, but I wanted to make sure I practice the best practices for my PSU and GPU, and I was curious does the 750w P2 Powersupply come with 2 PCI-E cables or does it only come with one?
