As an avid miner I am always on the lookout for products that will enhance my mining experience .This Dual 6Pin Graphics Extension cable pack did not disappoint! Industrial and Scientific-grade quality was evident upon unboxing. As my tests showed, the CABLES delivered consistent power to my graphics cards which resulted in stable hashrates. The only downside is that it's a bit pricier compared to other extension cables in the market, but it`s worth every penny for the quality and peace of mind it brings..
