Hello, thanks for the help. It looks like you may have a lot experience with s17s. I wanted to ask, cause while doing research I seen that people said they got better psu and fans for their s17 miners.
Not sure where you read that, but that isn't correct, the only thing you need to do when planning on buying Bitmain 17 series is to reconsider your decision because chances are you are going to regret it, I don't want to go into details since this topic is more of "electric setup" but you should really avoid getting those gears.
most top out at 250v rating and running anything higher is a very bad idea...
Ya, he will be limited to a few models, the most famous among those who have 277v is gears that use P21 PSU like the M20 and the M21s, the input voltage of that is 200v-277v, in fact, the overclocking function in the latest stock firmware requires a higher voltage than 240v, which is heaven on earth as far as those folks are concerned, the price of those PSUs, however, is just way too much, it's more expensive than buying two regular PSUs that run at 200-240v.
