Thanks! Yes, I forgot that it took a few seconds to turn on. I successfully turned it off for a about 8 hours so I could examine the power cord to make sure it was the correct one because it was getting very warm. It was the right one. Is that normal for it to get hot while operating - the cord? I can still touch it, but it doesn't feel right. Could this be an issue with the amount of power the outlet is providing or is it possible the cord is too old and I need a new one? Thanks!
Getting warm is not really a great thing for a electrical cable. Are you sure it is original cord?
And can you define "very warm" that is not something good if it's as hot as I think your saying. Yes it could be the amount of watts of a S4 if cable is not right gauge. So check cable and see if it is original. And even if it is if getting "very warm" might be worth getting a new better gauge wire.
Thanks. It sounds like it is too hot to be good. So you think it has more to do with the cord than the wall if the S4 has been running just fine at full hash rate for a 5 days now? What kind of power cable would you recommend for the S4 if I need a replacement?
