Q: Exactly how many PCIE + CPU cables come with this PSU?
A: CPU cables (called ATX 12V or EPS12V cables): There are 2 cables. Each cable has a 4+4 pin connector, which means you can plug it into your CPU power socket. PCIe cables (for your graphics card): 1 cable with a 12+4 pin connector (this is the new big one for the latest GPUs). 3 cables with 6+2 pin connectors. (One of those cables actually has two parts: one 500mm and one 150mm length, so you can reach farther inside your case.) So basically: CPU cables: 2 (for powering the brain of your PC) PCIe cables: 4 total (1 big 12+4 pin + 3 smaller 6+2 pins) If you’re plugging this in, just remember: CPU cables go to the processor area on your motherboard. PCIe cables go to your graphics card. No sweat, you got all the cables you need.

1200w is a bit overkill for most PC's, but the peace of mind knowing that I never have to worry about my PC having enough power, lifted a wait for my shoulders that I didn't know was there. It gives me the freedom to upgrade the rest of my PC in the future without worry. If you can afford it, I definitely recommend it.
