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).
You have to remember, most of the time when someone like dogie suggests an item and it contains a hidden link to Amazon or the like, he has an associate tag embedded and receives commission on EVERYTHING in your shopping cart. Not just that one item. So please don't trust those links. Don't click on them. They force your cart to give him commission for the next 24 hours! Trust anyone else who links. Also cross check ratings of those products with other reputable outlets. newegg, overstock etc. Whilst you may not be able to purchase from them, you can at least trust their rating systems over Amazon.
