Most psu can run over spec 10-20% for awhile, I dont know about the build quality of Enermax, maybe thats why they dont ship as complete units anymore.

Corsair and Seasonic Plats are pretty good.

I'm thinking about a Corsair 1300, but would hate to drop the cash if it won't really "buy" me anything. That said, what are the odds the upgrade blades BM has referred to will come it at lesser wattage?

I'll probably just bite the bullet and replace the PSU, my S2 slowly works down to 970 GH/s, even though only 4 chips are showing as disabled. I'm guessing my PSU is acting up.

1000w is clearly NOT ENOUGH and anyone who hasnt upgraded is losing GH by the second.

......

anyway - ive learnt that they need more power for a fact and i will be lucky if the ever helpful bitmain can sort me out

My batch 4 S2 is running quite happily at 1005 GH/s on the original 1000W PSU, (1086W at the wall). Not sure where you're getting your facts.

How long can that PSU run overspec? That it's running fine now is great, but how long will it do that? I'm not being confrontational, I'm an owner of an S2 and am curious.

...better than early Batch 4 with 10 cards by quite a long way

not as good as batch 3 with 10 cards.

the batch 4 seems to dwindledown to around 850 . i did ask about this on another thread.

anyone experienced a dwindledown rig??

I must admit that mine has done that from time to time and I've not figured out why exactly. Sometimes I found it was leaking shares to my backup pool and other times I found pulling and reinserting the cards helped. I also found that the gui would sometimes report a different hashrate to the pool and I think that was due to the ntp going out of whack or something, try clicking Save&Apply in the Miner config and see if it starts cgminer with the full hashrate.

I assume this is an issue with the PSU, but I'm not an EE. Has anyone seen this problem after upgrading their PSU to 1200-1300?

For French users :

Je viens de recevoir mon S2 en France.

Les frais de douane sont de 303 €.

Je l'ai payé 3.366 BTC le 29 mai soit 1514 €.

Cela fait donc un total de 1817 €, livré par UPS.

Le colis n'est pas encore ouvert, je vous tiens au courant de l'état de la machine dès ouverture.

For others users :

I just got my S2.

French Customs fees are € 303 .

Price on 29 May : BTC 3.366 = € 1514 (with coupon)

Total = € 1817, delivered by UPS.

The package is not open yet, I'll let you know the status of the S2 as soon as possible

Not good to hear your machine with 9 cards hashes better than one with 10, these earlier machines seem to have some variance like the S1's. That's strange because my PSU gave up after a few months and wouldn't run 10 cards. I got it replaced by Bitmain with another brand new Enermax 1000W in the box and a new power board and that is up and running now for a couple of weeks. I also got my 2 damaged boards replaced on Monday and I'm running all 10 now at 1003GH/s... I'll have to see how long this psu lasts, but it looks good for now although it might be a bit early to tell.

ok so i went balls deep and powered her up - 9 blades hashing @ a better hashrate than my other S2s that were not damaged and are running 10 blades....

1000w is clearly NOT ENOUGH and anyone who hasnt upgraded is losing GH by the second.

myself included...

@freebit - despite my last 6-7 orders being dleivered by UPS , this time i was blessed with the talents of SF shipping..

25USD fee

instead of the 100+ from UPS (my personal choice)

and the 300+ from DHL (who are villains)

so when shaving pennies you clearly do get what u pay for - it looks as tough this rig was removed from the box, foam and bubblewrap then thrown onto the floor with some force before being repackaged minus the bubblewrap that was just stuffed inthe side.

anyway - ive learnt that they need more power for a fact and i will be lucky if the ever helpful bitmain can sort me out

rig ordred on 25th just arrived.

No metal plate holding the boards down

a huge crease all the way across and 2 corners dented & scratched.

damaged boards, something silver and red missing from the power board (capacitor? its not inside unless the psu has eaten it)

this will be my karmaic reward for being flippant on others troubles...

as well as awful shipping - zzzzzzzz

Bitmainnnnnnnnnnn!!!!.........

Did they come with the cable for the board to the LCD or the io board ?

came with all cables but is a complete S2, not the 'kit' you are thinking of.

also came with a missing cap a half dozen broken caps and odd looking extras on all the boards (which were also all damaged)

this is the kind of delivery i have been dreading...

already contacted bitmain and crossing my fingers it doesnt work out to be a bunch MORE wasted time

Good luck Edgar, it seem the longer UPS has these things, the more they get damaged.

Ok, Micro Center did not have a 15A cable, only 10A cables. So I am out of places to go today. If I were to take out a hashboard or two, will it run on a 10A cable just fine? Or would you guys recommend not doing that?

Just cut the supplied plug off the cord and put on a new one, you can just buy a plug from the hardware store. Otherwise, just take a cable from a printer or kettle in you home and use that.

To Micro Center! (love that place) It says 240V on it, so I assume its a foreign plug. Thanks for those who helped.

Better check the PSU for a 110/240 switch on it. Make sure its set correctly before plugging it in.

ALL current PSUs are auto-switching including the garbage Enermax that BitMain uses.

To the OP, if you're in dire need and can't wait, just take any power cord from a PC or another less powerful miner you have laying around.

Btw, this is an annoying oversight by BitMain. Why haven't they corrected this by now?

I just bought one of S2
Price with coupon 2.92BTC

interesting...right now buying or "holding" btc seems to be the best tactic. Plugging today's price into a calculator gives breakeven in december with a lot of work and care and "only" 14.4% average difficulty rise per cycle. Buying was best at the group buy price. selling miner will be best at around the next BTC peak (could be July). Buying now and enduring ASIC miner 30PH/mo deployment for 3 mo plus KnC unleashing another 10-20 PH-a tough call. We could be back to the 20% difficulty rise each cycle for a couple of months at least, maybe even 3 months.

Yep! Until the price falls a bit and the "hodler" sells low in a panic. Funny how buy-and-holders never take that scenario into account. Mining=bad. Holding=good. Pshaw!

Btw, why isn't buying now bad? Isn't the market price a little too optimistic right now?
