@Tech9 I do not know what is situation of this user but post is for everyone. I had got situation in the past that to look better new internet cable at home was placed outside ( id do not care about reason) therefore depend of place on Earth like Poland during winter time could be -30C and during summer close to 40C - 70C difference for me is something worth mansion especially if you will think about changing advice by Asus power supply.
