I've built at least 10 systems with this power supply without any issues.
This thing is a beast. Runs cool bottom exhaust. All your power needs for SLI.
Plenty of power and modular connections.
This power supply screams high quality. Powder coated paint job, Eco-mode, umpteen different modular connections, a 10-year warranty, and a pants load of power to run any non-SLI/non-Crossfire gaming machine.
I would highly recommend this power supply.
Con: a little pricy, but it is worth every penny.
