Can someone tell me how many 6pin connectors are needed and what psu would be good to power one of these please. Currently got a corsair cx600m running some rboxes so got three pci connectors (one a dual molex to 6pin converter).

Thanks.

There is 7 PCI-E power connectors and it is recommended to use all of them.
Three PCI-E power connectors is way too little amount.
And you would need to underclock it if you are running it with ~600W PSU.
Based on my experiences with Avalon6 you could try with 2 connectors per board and one for controller -> total of 5 PCI-E connectors and make sure that the connectors won't heat up. Just make sure that the wires are at least 16AWG.

Are you asking this because you have other plans for the Enermax Revolution 87+ 1000W PSU that comes with this?

edit: Oh, I saw your posts in sidehack's thread and realised the reason.
For his version of S7-LN Corsair CX600M would be enough but you still have quite little amount of PCI-E connectors.
5 would be great.

Right, the picture I posted of the rear 3 pages back had the fan removed and was more showing the boards than the miner.

Anyone else notice it might be better to flip the fans around the other direction since the power supply exhaust is pointing to the front and will warm the cooler air in front of the S7-LN and be drawn back into the AntMiner? Also is anyone pointing their S7 vertically like they did with the S5's? If so, does it help? Hard to believe, but I haven't been able to find one single picture or video of the rear of the S7-LN. Anyone that has one, can you post a pic. of the rear.

This might be covered already, but.. whats the noise levels at?

Cheers

I don't have a noise meter, so someone else will have to give you specifis. But for me, in a fairly warm house (73 in here right now) I would say it's no noisier than the small window air conditioner I have in another room.

Update: Used an app on my phone. Was getting 64-71 decibals at my desk (2 feet away) and 80 4 inches from the exhaust fan.

yeah I am having sidehack mod the s7-ln for me as are others.

looks very promising.

Yeah the full S7's were too loud and drew too much power for my old house's circuits. The LN is just right for home mining, and I plan to get a few more to put in different rooms.

Would love to see an S9-LN also.

Yeah, I meant 2.1Ths. Good little miner.

42 Degrees on the boards, and it's not super-heating my office. It's also sitting on the floor right next to my desk and the noise doesn't bother me at all.

I really hope that they make a S9-LN model as well!

The way it looks right now, the S7-LN is a really hot item. If they ever make an S9-LN, it'll probably be like how the S7-LN was made- right after the last few batches of S7. I think Bitmain will continue in the future with normal Sx miners and Sx-LN in the future instead of their old rackminer and U series - it's earned probably a lot more than either of those for Bitmain, and good for us too- the power supplies alone cost a ton, and the price is justifiable where you can just remove the psu when the miner's spent or you don't want to mine anymore. Great combo miner imo, better than the cheap 1 fan S7s they made.

Ordered one last night and it's scheduled for delivery Monday! Pretty good service!

Came today as expected. Well packed in foam, all parts look brand-new. PS still had protective plastic on it.

Got it underclocked to 2.1Ghs to make it quiet and not so hot - though it was pretty quiet out of the box.

2.1GH/S??? I think you stopped all the ASICS but one. Good to know that the PSU'S are at least in good shape - was worried they could just go to the trash dump and find some random 87+s and put them on their miners ready to ship.

I guess he meant to say 2.1Th/s.

I did not even catch the 2.1Ghs. I only saw 2.1 TH/s in my mind. That is what I get for reading this stuff in the middle of the night.

Hot is something else- was it running hot at default? There's probably no space for oc then.

I guess I kinda over worry about things, like heatsoak , from the sudden loss of fans while running heavy.

I've been killing the miner by killing mains AC into the PSU. My meter box is wired with a switched outlet. I've power-cycled it probably 50 times and it's come back up every time.

I haven't found any "Halt" or "Stop" buttons in the Luci, is it "safe" to just flip the PSU power switch off when it gets too hot in my room and I need the A/C to get a chance too catch up?

When I noted I could run 50C boards in a 73F ambient at 20% fan and 2TH, I was at home and running the miner overnight about five feet from my head while sleeping. A lot of the tests have been at the shop, where the ambient has run between 90F and 100F for pretty much the entire time. I'm pushing it about as hard now as I ever have (710mV 775MHz for 1018W of draw) and I'm seeing 63/65 from about 90F ambient, fans 3120/3240

All the S7 hack links are in the first line of my sig - the thread and the group buy.

All things being equal, temperature should be proportional to total power dissipation. As your power input goes down, your heat output goes down. So yes, the thing will stay cooler at lower frequencies.
