So I'm currently on the fence between the cx750/cx750m, the dell Z750P+gekko science board, and a IBM Blade Servers (DPS2000) ($40 off ebay).
I'm currently running two antminer s1's (dual blade) connected to one cx750m. Everything appears to be running smoothly, any critique's on this setup?
I will be buying a lot of antminer s1's over the next couple of weeks, The psu's I buy from here on out I'd like to be scalable, which from what I understand could be any of the three power supplies I've mentioned above. Suggestions?
Eventually I will be swapping all the antminer's for monarch's, but that will be farther down the road, however I would prefer to not have to buy new psu's. Obviously we don't have power specs on the monarch's yet, but from a rack power and organization standpoint, if you are going big which of the three psu's above would scale the best?
I noticed no one has mentioned redundant power supplies, why not?
I also noticed no one has mentioned UPS's, what are you guys using for that?
Are there any advantages to running psu's in sync when they are outside a computer?
In relation to house circuit power, as long as I'm not blowing any circuit breakers, I shouldn't have to worry about if I'm on a 15A or 20A or 30A circuit right? I only should have to start looking at that when circuit breakers start tripping? Or in other words, if I need more power I should just run another 15A circuit right, not try and increase the 15A to 20A or something?
Someone said somewhere about keeping your circuit power utilization under 80%, is that really necessary and if so any suggestions on metering devices?
750s are too close for 2x S1s overclocked in the long term as you'll be running them at ~825 24/7. If you want a solution for super long term, get
1200AX's. They are expensive, but you can load them at 1300 24/7 (3 S1s OCed) and they have a ridiculous 7 year warranty.
Redundant power supplies cost twice and much, and its not mission critical. If a PSU fails, you unplug it and plug another one in. Nothing lost. Same with UPS, it costs so much to have even 10 minutes of backup power for a mining operation, but the cost of 10 minutes of interruption is virtually nothing.
No reason to sync PSUs unless they're bridged (powering the same hardware).
If the circuit is rated to run that current, it will run that current. You can run as many circuits as you like as long as none of them exceed the spec of the wiring, the circuit and the overall system. Consult a qualified electrician.
PSU efficiency is highest at around 90% but the difference is minimal.
