A:AnswerYour best bet is to NOT get these. See they have some problem where they will just stop working and you have to unplug then plug back in. USB power settings do nothing.. USB2 or USB3 does nothing. This effect happens on ANY computer. The TINEST static will shut them off. To this day about a year later they CORSAIR have no answers. Well you can read on Corsair forum telling one person to update the firmware. Well Corsair told me there is no firmware for these. I am still looking for help and NO ONE at corsair helps...sorry Corsair I have and many have asked.
