I prefer EVGA and Corsair had some issues with some models around the time I bought my upgrade. So for me, they are a no-no even tho people say they got better again. The only bad thing that's also good cause your cables are safe and will last longer, is the fact that the cables are huge and well protected, so you need a case with a lot of space on the back if you want to hide them or make good cable management. Also they have good customer service and 10 years warranty. For SLI you might need more, depends on what Nvidia does in the future, this Pascal generation the power consumption went way lower, but we don't know in the future, that's why I explained previously.
