Title: Little Single PSU is dead Post by: mufa23 on October 31, 2013, 09:24:37 PM (I posted this over at BFL's forum, but thought I'd post here for some quicker responses and a second opinion)
Last night I noticed my Little Single was off even though it was plugged in and everything. I unplugged it from the wall, plugged it back in, unplugged it again. Waited ten minutes. Plugged it back in. And the PSU finally started working again. Aparrently though, it turned off again overnight. So I am thinking the PSU is dead. Now I can use any 6 pin cable from my computer's PSU right? I was thinking of having my PC and Little Single running off the same PSU. The LS and my PC would start up when I hit the power button on my computer, right? How much power does the LS pull? I'm guessing ~100w? And will BFL RMA my power supply? Thanks, Mufa Title: Re: Little Single PSU is dead Post by: Easy2Mine on October 31, 2013, 09:48:41 PM Yes, it will start up when you power up your computer.
I am using Corsair CX750M and Cooler Master GX750 PSU to power the singles. Each PSU can power 2 BFL singles and they are pulling 490-520 watt at the wall. I don't like to jumpstart the PSU's, instead I bought 12 PSU tester to jumpstart the PSU's. I bought them here. http://www.blueface.nl/atx-voeding-psu-tester.html Title: Re: Little Single PSU is dead Post by: Unacceptable on November 01, 2013, 03:20:11 AM (I posted this over at BFL's forum, but thought I'd post here for some quicker responses and a second opinion) Yes,if your PSU is big enough,you'll need at least 130-150 watts per 30GH'er.Last night I noticed my Little Single was off even though it was plugged in and everything.

The PSU should kick on when given power, and otherwise work as advertised.
Since you won't be using too much power, pretty much any PSU will do - I've used the cheapest, most off-brand junk for a car radio and other stuff.

Countless people have had BFL PSU failures. The quality of the BFL PSU is down right atrocious and dangerous.. Buy a quality PSU and use that. And anyone that is still running a BFL PSU with a single, I would advise to replace it with a quality computer PSU ASAP. Your safety and property are not worth a few extra bucks.

My fire was inside my Single rather than the PSU. I just happened to be sitting next to it when it clicked and then I saw white smoking blowing out of it as the fans spun down. Scared the living crap out of me since I haven't seen that much smoke since I miswired the switch on a old AT case back in the 90's (Chinese instructions were wrong - shocking... no pun intended).
I think any miner has the possibility to catch fire since they are pushing the limits of some component on the board that was hastily designed (we've seen fires reported in Avalons, BFL & KNC devices). I just hope running my devices on a ceramic floor away from other objects is enough to save me. |
