Summary: Compared to XFX's Pro750 power supply it seemed a bit lighter thus I am not sure about the longevity of it. It weighted about the same as the old lower end Corsair 650watt (3 yr warranty). Modular is nice with plenty of slots to do up to quad GPu I believe. nice of them to use Velcro for each bundle of modular cables, I reused those for cable management in the system. Reach is good don't have to snake them between ram and heat sink and the PCI slots to plug it in.
