by the way are you guy using any other power supplys than bitmains if yes which ones and what are your experiences with them
I'm currently running on 120v, so just to be safe I have one hashboard connected to a 650W gold+ evga psu (the other two and the mainboard are apw++). Once I swap over to 240v it'll just be the apw.
But point being--it's running fine. I've had stellar luck with evga psus, I have 2 of my three rigs running on their high end platinums and an S5 on a second 650W gold. A little pricey, but their gold and platinum lines are worth it.
