I received the PSU the other day and went to check on it after a few days of being used.  The PSU is warm which is normal but the cable from PSU to the miner is warm too.    i would say just 1/4 of length from PSU to miner is warm.  I'm not sure if the cable is supposed to  be warm?   

When i had my other PSU plugged in the cable wasn't warm.  So just want to double check on this.
