Sometimes I wonder why people like this even bother replying... the whole point of me making a post here is not so I can brag about what I already "understand".... it's clearly because I don't and have a question to ask and would like an answer.

Ugg I'm not trying to be a jerk man but you are just really missing some big electrical concepts and I don't want you to fry your unit. Let's say it this way, the D3 run's at ~1100 Watts on 13/13/13 at 120v that's 9.2Amps (1100/120 = 9.16). That's your power draw. If you are on a 15 amp breaker switch you shouldn't put much more on it, typically 80% of the rated breaker is the max an electrician will tell you (15 * .8 = 12 amps max). Anything more than 12 Amps on a 15 amp breaker running CONSTANTLY might pop the breaker switch. Now that is out of the way changing to 13/18/13 will draw more current, I'm not sure how much but what I will say it applying that much voltage to the board has the risk of overheating or instantly electrocuting the ASIC chips on the hashboard. Thus if you don't understand these concepts I'd highly recommend you not to go past the 13 setting.

Agreed 100%. Learning more about messing with electricity is key if you don't want to trash your gear.

That said, if you want to mess around and are more concerned about draw than damaging your D3, you CAN pick up a kill-a-watt and figure out your voltage/draw without math.

Honestly with 1200 potential output, the odds are that the psu would fry (read might even catch on fire) unless it has alot of over this and that protection built in, not gonna trip a breaker or even really fry the machine (unless burning wires melt the plastic 6 pin plugs) the boards though can handle more than the 13, there is just no significant gain (I know he didn't care about that my point is you would be pouring more electricity in and getting nothing out of it really. I mean going from 13 into the 20's and maxing out freq step by step until you get a bunch of errors you go from like 19ghs to 20.5 and who knows what the difference in watts are... anyway he asked if it would trip the breaker, and no it won't unless there are other things running.. microwave or vaccum cleaner? miner on=instant trip. 13 to 15 though probably won't make a significant enough difference - not 100% on that since I neither have a kil-owat meter nor do I have a way to see the miner-side draw. - if that goes over 1200..well unless there is an overtemp trip in the psu things will get hot. - maybe news at 11 hot...(//edit for adding :over 1200 miner side - at the wall he has a limit of about 1600.. the 80% figure above comes from cheap contractors so maybe go with what homeboy said.. assume cheap assed bastards.. hehe I put in my own wiring fairly often and forget that other people don't go.. I'm putting a 10 amp breaker in.. use 15amp wire.. putting in a 20? use 30 amp wire etc... it's kind of a thing of mine. //)
