So, the electrician is coming tomorrow morning to get me set up to mine with x4 S9's. I am still a little unclear as to whether or not I can put all 4 miners on a 30AMP circuit, but I don't know what other choice I'll have. My concern now it that the APW3++ PSU are 1600W. Does this mean they are always running at 1600W or that is the maximum that they run at? I will be receiving the late November batch of S9's and they are rated at ~1350W. Thus, 1350 x 4 = 5400W. If the 30A circuit has a voltage of 220, then that is 6600W....5400W/6600W = right around 81%. Close enough to run continuously with no worries? However, if I am wrong and the PSU's are always running @ 1600W, then putting 4 on one 30A circuit may not work. Can someone please clear this up for me? Do the APW3++ run at 1600W always? Or, is that just the maximum that they run to accommodate whatever device they are dowering?
Thanks in advance!
The PSUs are RATED for 1600watts. That means that if the miner needed it, it could provide it. However, as you have said, the S9 SHOULD only consume about 1350w (depending). I think you will be just fine with the one PDU, the worst thing that could happen is that you trip the breaker. But, depending on your voltage, you may or may not have an issue. You should expect to run around 24-27A.
Take note of the voltage when he comes.
