    modularity and efficiency

    This power supply is very well designed. It allows the cabling to be routed more easily to the back of the motherboard. This means you don't have to pull your hair out when you have big hands like mine. Power-wise, it's excellent too. The old one wasn't powerful enough for my 4070 (reboots and image cuts). I'm very happy with it.
    Buy with your eyes closed!
