Clueless!

Well the www.coindesk.com article below says that it will take 391 days to ROI for a unit with the included PSU. OUCH!

(of course as previously mentioned in a post you don't get one the BTC price is gonna go to $750 or $1000 ..that is how BTC and crypto work. (BTC: your merciless bitch) (tm)..ie missed boat action)

http://www.coindesk.com/bitmain-release-new-bitcoin-miner-bid-attract-hobbyists/

Then again winter is coming ...I could justify the 'toy' for the 'space heater' qualities....(that would be me in denial have 6000w in basement now with Titans...grasping at straws)

I mean where was this thing at this price BEFORE halving? (damn it) Sad

Looking at the above..there is a reason I am only running scrypt miners......this unit...(if ROI above is correct) is not attractive in USA with ave electric price of 15c kwh. (me 14c kwh)

Well anyway its pretty. Truth be told IF they made it with a ONE year warranty I'd get one and just call it a 'toy' and hope for a price pump on BTC as my justification. BUT 90 days

less than ideal imho. But probably the way of the world now.

So have we determined if the APW5 will power 2 of these on a 220 volt line?

So far ja it looks like it. Assuming 3 PCIe power per board and 1 for the controller that makes 7 PCIe needed per R4. Per Bitmains specs the PSU has "7 pairs of PCIe" so 14 in total. Perfect fit.

It seems like a nice ASIC interesting for those who like having their own mining farm at home. I'll follow this one.

one page pdf datasheet for APW5 - size 70MB :-))
It is probably possible only in China...

heh heh... is because it is an uncompressed PDF probably created/printed from a Word document that has full resolution pics in it instead of the documents creator dropping them in as a lower rez. I see that all the time in correspondence with our Asian customers.

We have one in Korea that seems to use Excel as their template for everything. They need to send us a pic of something on the equipment - it's pasted into a xls file and the file is attached to their email about the problem.. Roll Eyes

I spent some time with a few bitcoin mining profitability calculators, the ones that do take difficulty increases into account. If bitcoin price stays where it is a liberal estimate is your $1300 is repaid in just over a year and a half. Longer if difficulty increases ramp up. To earn your money back in one year bitcoin price has to go to $750 no doubt.

With publishing this "especially secret" information, you get probably 11 more negative Trust from Bitmain controlled accounts Grin

Do you have proof that bitmain has alt accounts? If you do, you should post them here.

Psu is EVGA 850w P2. I've got one of those leads but wanted to keep the wiring more simple if I could.

Do you think you could run one board to set it up and lower the freq and then restart it and run both boards at the lowered freq (I've only got an 850w psu)?

Sure why not

Just attach the controller and only one board. Set freq at 500 vs 550 and boom you are off.

If I get one I plan to run it at 700 or 750 gh

just remember you need 7 pcie cables.

Yep got plenty of cables. Well I've got four gpu points on my psu (EVGA 850w P2) and pci leads that split into two on the ends. Anyone know how much the average controller draws and if it can be run from a Sata/Peripheral connection point on my psu?

It powers the fans so 40 to 65 watts with fans but this is a new fan.

So a sata connection would be OK?

yeah what is your exact psu? something like this is good

https://www.amazon.com/Electop-Express-Molex-Power-Cable/dp/B01D0XATL8/ref=sr_1_1?

but use two jacks from the psu that way 2 yellow wires are really used.

Looks like they went to a long thin blower-type fan setup.
Nothing new there, except perhaps in it's application to Cryptocoin mining.

Price is going to be critical to acceptance, though it IS nice to see them finally backing down from the "barely able to power it from a standard 15Amp USA home circuit" level stuff.

In my opinion, this is one of the most beautiful miners I have ever seen. Will definitely be waiting to see what the price is for both this and the PSU, but it looks like bitmain nailed it out of the park.

EDIT: It also looks like the backboard has extra slots, possibly for a bigger model at some point?

Considering most miners don't look too good at all, this thing is actually pretty good-looking with the metal racklike frame and the cables :L

Maybe Bitmain's actually got plans for upgrading this in the future like you said- if they actually do, they should've posted that in the overview; it'd make the miner much more desirable to buy than it already is. Still a good miner in my book, just the connections needed from the psu... and the fact that the unit only takes 850 watts and that they recommend a 300$ 2600-1300W psu... not a bad deal, but they could've maybe created a psu more oriented to the R4 itself? I still like the APW5 brick design though, much better looking than the APW3.

fan is different but imo should me more or less the same BUT the bad part is that, you will NOT be able to find a replacement fan if it breaks down. !

board is slightly different in terms of the location of the pcie jacks, yes 3 of them & the heatsinks to suit the new fan & casing for the airflow over the heatsinks.

sadly no aftermarket parts readily available & hashboard too. good news is that you;re getting a longer data cable LoL.

I think the controllers are the same.

my guess was right, around 1.7 btc

PSU a little overpriced at USD 300 imo & why would you need 2600W to power a 900W miner & it comes with only 7 PCIE cables, you would need 14 to power 2 of them which is pretty good for those with 220V & up. hmmm

Hey, Bitmain, take your negative report against BitcoinNewsMagazine and shove it up your GPL-violating asses.

It's your own fault for not better protecting your links, and best we can tell, BitcoinNewsMagazine was accurate with information.

And here's silly me that was actually considering buying one of your new units for a nanosecond, before reminding myself of your recent warranty shenanigans, and blatant wanton greed.

Fucking amazing watching your fall from grace with this community.

Make Bitcoin glow with ENIAC

WTF Bitmain?!?!!???

I have defended you on all fronts and now you've neg rep'd BitcoinNewsMagazine for simply doing some quality journalism?

This is the exact product you've neg rep'd him for lying about.

If you can't keep a tight ship, don't go lashing out on people who's simply doing their job PROPERLY!!!

Looks like it's been sorted out. Good to see!
