So it's a good thing I ordered an extra miner on the first hacked group buy. I kept one because one of the boards wouldn't run stable at or below 630mV cold, so I pushed it up to 640 and left it on my shelf. I say "good thing" partly because of that, and partly because the PSU on it started misbehaving after about two days. Now it doesn't work at all. I switched it over to my known good test S7LN and still the supply trips out as soon as it lights up.

oh okay it sounds like the two I will send to European buyers will be okay using their own supply rather then the oem.

If you need some of the supplies  you can send all three modded s-7ln's to me sans psu's.



My one  and the two for Europe without supplies.  Hold the 3 as psu's spares for  the other buyers.

    At this moment  I have  8  spare psu's  all better quality psu's  plats and tits.   Grin Grin
 Sounds wrong so make that  platinums and titaniums. Grin

Bought myself a evga 850 p2 on your recommendation. Hooked it up the the old rboxs I've got and it's saving me 25-30w already lol. Nice bit of kit. Thanks for sending me the links philipma1957  Grin

Looks like they're finally sold out of the S7-LN.

yeah evga makes a ton of good psu's for mining.  I am glad it is working out.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

I don't see indication that it's out of stock right now.

Also, might have another lemon power supply. It was a bit sketchy and boards dropped out, but it appears to be running fine on a server 750. If so, that's 2 PSUs in 15 already. Not good odds.

I can confirm sidehack's observation regarding S7-LN availability. I started at the top, and was able to get down to the point of actually purchasing one. It still appears to be priced in USD and not BTC. Quoted price is $291 plus shipping.

A much better deal than the A6 I bought earlier this year.  Sad

Speaking of "lemon power supplies"... looks like one of 'em has a fan that wants to chew itself up.

Anyone else turned their fans around (so the heated air exits forward) and can confirm a noticeable decrease in fan noise?

And speaking of lemon power supplies... another one just toasted and tripped the breaker with it. Won't even power on. I scabbed the fan from the one dead one into the other so that one's probably okay, but I'm still down at least two, maybe three.
Also when I was swapping fans I pulled a dead moth out of the one.

Thanks a friggin' lot, Bitmain.

Also judging by the state of the screws and warranty stickers, three of these PSUs had been opened before they ever got to me.

Well, we knew the PSU'S had mostly been used before they got into the miners; it wouldn't be worthwhile for them if they were completely new. They were probably repaired by Bitmain, when suddenly they had an idea to sell these worthless psus with a miner, OR they were broken and they repaired it just to sell them. These could be the PSU'S they use in their farm.
No surprise either that they seem to be priced in USD instead of BTC, they have no use for these PSUs and they'd rather just make a crappy bundle out of it.

Its clear that bitmain is only out to make a quick buck since its introduction of the S5. I've read nothing but bad news with all the S7's and now S9.  As a owner of S1,S3 and S5 and can say that their attention to detail after the S5 is questionable. Ofcourse what  happened after the S3 was they didn't care about the noise.
I now have an Avalon 6 and think people should switch.

I assume it's for "Low Noise". Or perhaps "Last Nacho" (i.e. something related to the end of the S7 line).  Smiley

My @sidehack S7-LN arrived today, and is happily hashing away at ~2.0 TH/s and pulling ~450W at the wall using the Bitmain Enermax PSU.

Nice work @sidehack.

Cheers,

- zed

mine is at my buddies office.

the two head for europe will ship out on sat.

I am testing the Finnish one first
then the GB one second.

The stock psu is no big deal.  I suggest this one:

http://www.newegg.com/Product/Product.aspx?Item=9SIA1N83U90792&cm_re=evga_850_p2-_-17-438-056-_-Product

not cheap  look for it on sale.

Er?
I have 22 s7's starting from batch-1 of up through b18, not a bit of trouble with any of them. Ever. So far have 3 s9's running, all perform as advertised, no problems so far.

There. You have now read GOOD news on the s7 and 9's Wink

I think the stock PSU on mine is starting to go.  This past week the miner just went dead three times.  Each time the PSU was turned off.  Power cycling the unit would bring it back up for a few hours but then it would shut down again.  I down clocked it from 600 to 500 and it was stable for 24 hours at about 2.2th.  I have since upped it to 550@2.5th and knock on wood it has been running four and a half hours so far.
