Good lord indeed. That's a crazy setup. I'll recommend the AX860W.
For an enthusiast computer, you need an enthusiast PSU. The AX series from corsair screams quality. They are all fully modular and is 80+ Platinum validated. It also has a zero fan profile. When the PSU is using less than 50% (430W) the fan isn't even spinning.
It also has cords that's non color coded to make it look even better.
For a comparison:
