It is my opinion maybe wrong but I thought these are best machines from batches 7,1,3,5 they have ever made.
I'm trying to buy S7 from these batches but if no luck might consider from other batches,if you guys have any please reply here PM me your offers.

@tupsu wish i could buy your 3x S7s Batch5 but your price still seems high and you are selling them without PSUs :(

it is true that b1, 3, 5, 7 are typically the best among unmodded S7.
Forget it if you think that 0.55 BTC is too much, buy current from bitmain.

 The price is the same as when buying from Bitmaintech. But if you are in EU, then buying from Bitmain is with 20-25% VAT.

Batch 2 and 4 had some solid units as well.  Don't let the 4.66 TH/s @ 550 MHz put you off from considering them.

The best S7 I've played with was a Batch 2 that clocked to 650 MHz running at ~5.1 TH/s with a 0.0001% error rate and PCB temps at 50C when fans were set to 34%.  I have yet to see a Batch 1, 3, or 5 come anywhere close to that level of performance.  Even the Batch 7 I had clocked at 650 MHz stock ran hotter with more errors.

From EU   here is not a lot of sales for   APW3-12-1600 PSU

I have them 4 pieces, but I see no need  to sell them cheaply . All of them work great with S9.

Still looking for S7's with PSUs on reasonable price.
PM me your offers please.

If you're in EU, you need to accept that here are S7 more expensive , because for all of them have been paid 20-25% VAT .

If you want cheap S7, buy from America.
