What went wrong in your case?
It can't do full loads 24/7/365
It can do about 900 to 1000 watts.
There are better transfomers but they will cost.
Also the transformed power is at least 85 % .
So a 120 volt 15 amps. Loses 1.5 to 2.0 amps
Which means you are. 13 amp. Not a 15 amp.
Then you need to de rate since you are running 24/7/365 which means you are about 10 or 11 amps.
Say 11. And 11 x 120 is 1320 watts. Is the most you can pull at the wall .
Not done take 5 % for the psu power waste and you are now at 1260 watts.
The s9 pulls more then 1260 So it may seem to work as you would be just over the circuit and in a month something will smoke.
Like it or not. The evga 1600 g2. Or changing power lines are your best options.
