What would everyone suggest as a good backup power supply to replace the crap one that the Antminer U3 came with? Amazon links if they carry it preferred...
6A one from my rockminer guide.I really think we are all going to have to switch to ATX computer PSU's with breakout boards for these U3's.
Dogie I bought one of the ones you suggested after my first stock PSU melted. The replacement one you suggested lasted 4 days (at least it didn't melt or catch fire, it just died completely).
I had previously had 3 of those also die while using them for my R-boxes (the 5A version) but I just replaced them as they lasted 2 months before dying on me and I got them cheap ($6 each).
They're the same ones I'm using, and none of mine are even warm... Send it back and get another one.
