I would agree what OP said is just to close to limit. It would have to be OC'ed and even then most likely running PSU high on watts. What brand of PSU is it op?
Dont forget the bottom part in that post as I really don't like idea of PC and miner sharing:
But where are you reading it is sharing cooling with PC? I could be overlooking it but I just don't see that part.
PCP&C, or PC Power & Cooling, is a PSU manufacturer (relatively high-end).
I already have 8 S3s running on 2x 1300W EVGA Supernovas (4 each), split across two 15A circuits. It's silly to pick up a PSU for a single unit so I was just wondering how to make use of the 9th effectively.
I have chosen not to run it from my computer PSU as the risk of overload means a hard power off, not something my PC and VMs like very much. Also, I'm already riding 12A on each 15A circuit so I figured it's best to quit while I'm ahead.
I did this on a G2 750w. I personally would not trust any other PSU but the G2 right now to work safely at max load. If you have a wattmeter, you can check what your actual load is. Mine was actually lower than expected. I'm mining and gaming on my GPU at the same time and its a power hungry r9 280 and i wasn't even hitting 400watts.
With the S3 i was doing 700watts and the PSU can handle spikes no problem.
