could it be because I'm powering it from 2 different outlets?
No, that does not matter.
or maybe one of the power cord isn't robust enough? since it didnt came with cables I had to use some that I had laying around from PCs
That also is unlikely, what is the dimension of the power cord? you should do just fine with anything => 1.5mm2, but even with less, the cord will become warm to touch, maybe gets too hot, but I don't think it will cause this error in your miner, what could be the problem, however, is the voltage, are you sure yours is between 220v and 240v?
