Man of Honour
The fans will work with just the power connected but you won't have any lighting at all from them.
The thing that bothers me about that hub is that it's magnetic and I wouldn't want magnets anywhere near drives or memory. It doesn't matter what colour it is as the idea is to have it tucked away out of sight to cut down on the mess of wires. Personally I would stick with brands I trust such as the Thermalright hub I suggested which does power and ARGB lighting for 8 fans.
