I am not an electrician. Can somebody please tell me if I can run one of these on a standard outlet for an apartment in the USA? I would buy the power supply that bitmain sells.

In addition to the electrical supply in your apartment, remember that the S7 should be considered a LOUD 1200W heater. While nobody has tested one yet, every expectation is that it will be at least S5 loud. Think vacuum cleaner loud. Maybe Bitmain worked some magic, but the fans that are present are expected to be noisy and powerful to keep the 1200W blades cool enough. If that fits your apartment situation, then you'll be good.

Along with the above I will do a very long and through review.  Sound meters.  Different fans. ways to reduce noise.


That said.  At best  it will be 72-77db  and nasty pitched when it arrives.

I think I can do 65db and better pitch sound with high hash say 4400-4800.

I know I can do  45db to 50db with downclock to 3000gh

I hope I can do   45db 3000gh  and .18 to .20 watts.  with downclock and voltage drops.

see highlighted...really? (if measured with good dB meter)
anything at 60-61 db is already quite nice (Sp20 produces that much at setting 10)
if you can get to 61db at 4200-4400GH, it would be SUPER-i would definitely buy more then and I have some ideas about fan mods as well.

You know haters there is such a thing as a secondary market for these things right? There are lots of ways to chase ROI.

My thoughts on S7 purchase and profitability:

I consider that I am using $$ (even I briefly convert $$ to bitcoin), so my expense is ~1869 without coupon plus ~125/PSU=~$1994
Bitcoin profitability ~360 days.
however, used price of at least 30% (after selling expenses) at the end of this period makes it a 30% ROI in $$ terms.
Additional upside (but only in $$ terms, not in btc) MIGHT happen IF BTC price would go up.
You'll make the same or slightly smaller btc (due to difficulty rises), but make more $$ and aftermarket price would be higher.

May I remind you of something called "HALVING" before going crazy on a purchasing spree?

That is a million years away.  By the time halving arrives, each and every S7 will have long been tossed in the bin.  Miner lifetime is far shorter than that.

my Sp20 is still very profitable at $0.1/kwh after ~9 mo
My Sp30 is still profitable even without downclock after 11mo
Conclusion: difficulty rises in the last 10-12 mo were moderate, allowing good hardware to function longer

Stop jerking off your mind. Cheesy 10 months is not really an accurate equivalent to a million years. Regardless, you are actually adding to my own point: NO ROI in them!

A lot of us here are not mine owners, rather home miners mostly for fun. So your point doesn't make sense to me.

uhh, what is "funny" on sending ~2k USD to some chinese strangers? I'm trying really hard, but I don't see any "fun" aspect. Unbox, plug and play and time to time click broswe and upload new firmware..this is what you are calling "fun"?

if yes, you really don't know what "fun" for geeks is, but believe or not, it is not overpriced noisy box from China and you don't need to invest 2k USD to enjoy it, really.


Well, plugging in and checking the miner once a day is not what I am doing. I also have a GPU rig and always hang out on the altcoin forums, solo-mining some ninjas, mining some forgotten coins. If I was just mining btc, without even pool hopping it wouldn't be fun at all, I strongly agree. I don't expect you to understand this, if you don't know what I am talking about. Looking at the 2k hobby argument, I play WoW since 2007 ie. Burning Crusade expansion, I am paying 20$ avarage each month since 2007 and I bought bunch of special mounts and etc. This is far greater than spending a machine 2k (although if you look at my previous posts I think it is overpriced, like, A LOT!). I also like to have the latest gear.

Oh, and as you mentioned later, the last thing I am after is being rich through bitcoin. I am currently at my 2nd university education, I am a journalism graduate an active law student. Tongue

Fun stuff would be cheap things like sidehacks USB sticks..

yes exactly.

looking for real fun and want bitcoin flavor?

yes cool, so install your RPi, compile own linux kernel, start writing own drivers for fancy USB stick, experiment with Arduino kit or deploy small solar panel to power it, install temperature collector, start contributing to open-source or tweaking/hacking stuff, which you had already at home. this is what I'm calling FUN. at least for geeks.

I want to be f*cking rich like other guys here, calling "fun" by ordering 2k box with 1kW+ power consumption..Sad

Fun stuff would be cheap things like sidehacks USB sticks, whilst they are unlikely to ROI you can use them as a lottery ticket and solo mine, but I agree 2k for fun is not for me.

Real fun vanished at the end of the GPU era, so many combinations of things to try fancy rigs to be built and new firmwares and bios and drivers, and all the associated tweaking of clock speeds and voltages trying to get the most from every type of card.

I think we are just to old in the BTC game Smiley

While GPUs were fun I wouldn't want to do it again. Once is enough Smiley

Trying new types of hardware is fun for some people, to each their own I guess. 8 BTC is a hefty sum but not that much compared to the shit other people waste their money on under a pretense of a "hobby" Grin

..so somebody thinks here, that there is any bitcoin hardware manufacturer, which is selling mining gear with profit for customer (so you can mine more BTC, than the miner costs in BTC) in 2015?Smiley

after all those bubbles, pre-orders, scams, shills, courts, layers and bankruptcies..

no my dears, I'm so sorry but why they should do it instead of mining by themselves in country, with one of the cheapest electricity in known universe? Xian, Tigger and other smart guys are right. you will never ever even ROI your BTC with this fancy noisy chinese box..

I'm so sad for guys hunting some coupons here:(

That's where his points are right.
I do not mine for fun, i do it because it's fun to mine with my gear and make some BTC for later on. With this price and diff i stick with my old gear and hope for the BTC to rise  Cheesy
If you can afford 1,xKWH just for fun then you are a lucky guy, but the home miners do consider them selfs as part of the game and we want our chunks also  Grin
It would be funny to see who is mining at $100/BTC or lower.
I believe some bigger farms are getting in real trouble then  Wink
