I have brought this cable to run a SLI system to one of the two cards (both each equipped with Zalmann3000 cooler) with some distance to provide.
Initially skeptical, I realized: no loss of power or crashes as it is said in other previous speakers.
Several tests whether Heaven benchmark, Furmark or whatever they're called, ran from trouble-free.
I highly recommend this cable with a clear conscience and declare as strong buy recommendation.
