They aren't overclocked. They are straight outta the box. My wife is an interior designer, so all my miners MUST remain in my office so as not to interfere with her masterpiece haha. Not worried, though. I've got an electrician coming out here tomorrow and he's gonna put another circuit in here and I'll be back in business. Need a pro to look at it anyway. If the wiring is crap I need to know now before something terrible happens anyway. Thank you, mindtrip, for saving my family's life LOL
If your electrician is running a complete new circuit you may consider a 220v circuit (or two) dedicated for your mining hardware. You can run more off a 220v circuit, plus it's a little more efficient (which is always an upside) to run the power supplies off of 220 vs 110. I ran 2x220v circuits to where my miners are located and it was the best thing I ever did. If you do this, just be sure that it is recognizable as a 220v circuit. I have orange outlets and red stickers warning of the 220v circuit so 110v equipment isn't mistakenly plugged in (although I'm the only one that uses that area of the basement).
You should have used receptacles and matching plugs that make plugging in 120 V device impossible.
