Im having trouble with my miner. Been mining about 3 weeks now. I have 4 1080 tis on the board and it has already burned up a surge protector (causing the breaker to trip) and now I have it on a different circuit. Its making the 6ft extension cord at the wall hot. The most Im seeing it pull is 900 watts with watt meter. I have 15 amp circuits with nothing else but a overhead led bulb on it. The 2200 watt PSU does not say its rated for 110 (says 176-264v)  but Octominer rep told me it was fine to use. I have another non-octominer miner I built months before that runs the same amount of watts and does not get my plugs hot. Im worried about it burning my house down.  My guess is its the PSU. Anybody? TY
