EVGA 1300 G2's are perfectly fine with S7's.
I've run Batch 1's, Batch 6's@ 4.5TH with zero issues.
I've also run a few sets of 2x S5's overclocked to 1.25TH each for months with zero issues per EVGA 1300 G2.



Yeah but thats 1220~1300W at the wall. With B8 and B9 S7's, what Bitmain is selling right now, you're looking at 1415~1480W at the wall depending on PSU efficiency. So still fine, but very limit.

The efficiency of those is about 0.3J/GH/s with gold efficiency, versus 0.25J/GH/s of the early S7 batches.

Ahh, forgot that the newer batches' efficiency is crap.

OK, thanks. How about a EVGA 1300 running 2 boards and a CX750 running a board and the controller? Do you think this may work. The reason I ask is because I currently run 7 s3s, a s2 and a s5 on ~4200 watts. (3 evga 1300 and 2 CX750) I want to upgrade to 3 s7s which will put me in about the same wattage but I don't really want to buy too many more PSUs. Think I can make this work?

I think the S2 has a 1000w PSU in there that you could use as well.

Nope. I bought the s2 used. It had an EVGA 1500 watt PSU. I thought that was a bonus until it burned up. (wasn't as great as i thought) I replaced it with a 1300. That's where the 3rd 1300 comes from. I plan on keeping the s5, so I need 1 of the cx750s that I am running. I am hoping I can get away with just buying 2 more of the 750s. I'm not trying to cut corners but at the same time I don't want to spend any more than I have to. I figure with the PSUs I have I should be able to get away with just buying 2 more 750s. I hope.

I am running 3 S'7 on  the EVGA 1300's, but they are Batch2, 4.66 units. But I do have them OC'ed to 600 and getting 4.85 steady with .0001err on all 3. I am running the 3 boards on the 1300's and a CX750 to power the 3 controllers. Works great. Pulling 1215w per miner, again thats without the controller and fan. I have fans hard set at 28% for low RPM and quiet. The 3 feed my HVAC for heat and also works great, the fan on the HVAC runs 24x7 and does create a bit of negative air pressure to help suck the hot air out of the miners.

See picture



How do you duct them into the furnace? Dryer vent hoses?

You can see in the pics, I just cut a rectangular opening in the side of the intake, right before the blower and filter and placed miners right against the opening. No need for hoses or anything. I used sheet metal shears, cut 3 of the sides and folded inward. In the summer I will pull the sheet metal back and tape with metal duct tape they use on duct work.

Can you power an antminer s7 off an evga 1300 and a corsair 500 watt psu? I'm thinking the 1300 for the blades and the 500 for the controller. Would this setup work?

Assuming B8 or B9 unless underclocked I don't see running 3 blades off 1300 watt's.  Also I don't think it comes with 9 PCIe cables (could be wrong been a while since I have opened a box to one).

It would be the evga 1600 to run all 3 blades if you want to do it off 1 psu on evga series.  I would look at 220/240 if at all possible and there are some great server PSU's.  They have really taken over S7 market on PSU's being used.

Might be a bit rough with the B8/B9. The DC draw is 1292W~ so it would be running the 1300 to the max. Doable but a bit inefficient electricity wise. There would be no problem whatsoever with something like the 1300 G2 + seasonic. I did 1050 G2 for 2 and 750 G2 for 1+controller/fan and i got an acceptable borderline 1440W AC. I'm guessing with only a 1300G2 you'd have up to 1480W AC.

This is because i am on 120V 15A breakers, so the 80% load limit is 1440W at the wall.

I have a couple 162 chip miners and can hash them well above 5200 smoothly without hardware errors. I will receive my batch 9 tomorrow, not sure how much I can push these to. I usually wait until Philip reviews the higher frequencies lol

Kano is the best!

Anyone identify the place of the thermal sensor on the s7? Maybe this time they didn't put it at the middle of the blade as in s5!

Yeah I can get him to do it this thursday.

  We mined at f2pool since dec 29th

I will do a chart show him what it netted and then get him to to mine with kano.



Good stuff! I'm confident more will be earned using kano over the same length of time. Smiley

Got your point fellas)) will examine the info and direct my miners to keno or some other pool, maybe eligius.
There was time when me and my fellas mined at btcguild but almost all of us fall for the daily payouts from f2pool.
And according to my example everybody moved to f2pool so can I do it to some other pool.
Of course I want the best for myself and the fellas, but we do care about the the enviroment)) 
Not so long ago when my buddy purchased a node and was minig solo his server was constantly attacked (we think from china), and he stopped the solo and continued with f2.
But what wanted to say - even if we have payouts less then now -3-5% it will not effect our willingness to care about the btc ecosystem. we do care Wink

Thank you for that!

if we put in a dryer outlet, what cord would we need to convert from a dryer outlet to connect to the unit?



Are you running the Bitmain 1600w PSU directly to the wall? or using a pdu or some other sort of surge protection?? That will determine what plug to get.

I picked up some used APC AP7911 switched PDU's which work awesome and can be controlled remotely. If you go this route you will need c14 to c13 cable to run the Bitmain PSU to the AP7911 PDU and then you would need a NEMA L6 30R outlet. The APC Ap7911 has an AC power cable already.

If anyone is looking to sell a 162 chip S7, I'm buying. Transaction will be escrowed with OgNasty, PM if interested.

Lots of scams lately.  People been randomly asking me if I wanted a S7 for sell but once I asked about escrowed, they would say they don't trust those people and reference previous escrow scams and request to go LTC escrow route.  Buyers beware.  I know some of you are complaining that this is off topic but it isn't as it's still S7 related and they're trying to feed off the audience of this thread.  I think it's the same person as I would get random message saying they saw me asking to buy S7 but I never did say that.  If they don't agree to Escrow, you know it's fishy. 

@ Charles2K  - There's always been that message for FEDEX.  My brother in law paid extra to go with UPS after he saw that message and he end up having more headache then I did and pay $32 fees for 2 S7 vs none for me via FedEx.

After confirmation order this red written message appears (if shipping by Fedex):

"Generally, shipping with Fedex will take 3-5 days.But if it's spot checked by customs before exporting, there will be around 2 weeks DELAY.You only have 5 days to process customs clearance, if no action or failed, miners will be returned to sender by customs. You'll have to cover extra cost. "

Why? I never heard about it.

With UPS shipping option there is not such message.

Evil beware: We have waffles!
Stock picks based on past performance have nothing to do with random chance. In stocks there are Humans 'with a Plan' guiding performance vs random events. That Human influence throws a huge bias in a stocks performance. Yes random outside events will have an effect on performance but nowhere as near as much as the Human guidance does which will deliberately work to offset serious random disturbances..
