Can someone explain how the September batch 2 SP30s (and I assume other batches) have 2x 1200 watt PSUs and draws 3000 watts at the wall?

http://www.spondoolies-tech.com/products/sp30-yukon-september-batch-2

They are 1200W PSUs, but can provide more power, almost 20% more. 1200W is their safe 80% certified load. In reality you are looking to have 1350~1400W PSU. You can find the datasheet for both of the PSUs in Guy's posts.


Already been discussed a few pages back.
My understanding is the PSUs provide 1200watts output, but 1500watts at the wall.

NO. ~1350-1400W output 1500 at the wall.

Spondoolies or Roadstress, how will the difference in higher power consumption affect the cost of monthly hosting in the US datacenter?

@ Bitfury debate

At the end of the day it doesn´t really matter who deploys the huge farms.


Sort of.

I think it is our responsibility to not order equipment from folks that harm the bitcoin ecosystem.  I haven't been ordering equipment for a long time from Bitfury for these reasons (same reason I don't use ghash.io)

who cares about the reputations of bitmain, and knc they are the reason why diff is so high what they are doing with thier datorhalls is totally against the spirit of bitcoin.  Their double dealing stinks I have no problem with sp tech badmouthing them.

Yes, because bitcoin mining was invented to give YOU a profit and totally has nothing to do with the security of the blockchain right?

Every manufacturer I know of has their own farm (besides SP). It's time people stop pretending that mining is a game for the little guy.

You cant be serious right ? the bit fury CEO stated that he wants to own close to 50% of all bitcoins minted , the whole point of the bitcoin network is decentralization
to combat the big banking institutions that preload the economic dice with thier huge influence infrastructure and power.  If Santoshi had wanted big huge mega farms he probably would
have made the code closed source but guess what adoption would have been way slower if at all.

Like i said i give props to SP-tech even though they have issues with their sp30 for the fact that the at least ship their CUSTOMERS hardware out on time instead of using customer hardware to
mint thier own coins and then send out the hardware late and in a used state thus reducing the potential customer ROI with increased nethash funded by guess who CUSTOMERS.

I never do pre-orders but i did this one just for the fact that SP tech ships thier hardware and strong state that they will NEVER create a megafarm, if that holds true we will see.

The only way you can take up for these DATorhall (KNC, BF) hardware vendors is if you are one of then personally they get the middle finger.

  For several weeks  ghash.io is only 42- 47 Ph/s
I  get each block today  BTC 0.0111  Found blocks last 48 hours - 96
 Did you get somewhere better?

Zvi/Guy:

Can you foresee any problems with using a voltage of around 253V to power the SP30s?

I see that both PSUs are rated for up to 264V. I don't see efficiency statistics for any voltages above 230V for the Emerson or Murata in their datasheets, but based on data I've seen for other PSUs (e.g. http://info.servertech.com/blog/?Tag=power%20efficiency), efficiency should increase monotonically with input voltage as long as the MOSFETs can handle the voltage without breakdown (i.e. you're in the rated input voltage range). Judging from the sparse data I've seen (e.g. IT Power Supply column of the table in the link above), the increase from 240V to 253V might gain us maybe 0.25% to 0.4% in efficiency. Higher efficiency should mean more power available with the same PSU thermal load, which could mean more performance. If 253V boosts the PSU efficiency from 92.0% to 92.4%, then the PSU should be able to deliver about (1-8%/7.6%) = 5.3% more power for the same amount of PSU internal heat load, which might translate into 4% higher hashrate, as long as we tweaked the firmware to permit it. Those numbers probably aren't very accurate, but maybe they are in the right ballpark. What do you think?

P.S.: I received notice of shipment of my July unit yesterday. It's scheduled to arrive tomorrow. Thanks for your hard work!

I think July batch was no more than 100 units.

August was roughly 1000 units total.

About 5 Petahash then. Thanks

Am I to assume your including yourself as one of the "little guys" or are you the "little guys" spoke's person? Just curious.

I'm a little guy and so are you. (Unless you've got a multimillion dollar operation going on)

I've read the bitcoin whitepaper and I don't remember anything that says the point of bitcoin mining is so anyone with electricity can make a profit.

Sometimes I can see YOUR viewpoint but admittedly, most of the time I don't. What I was meaning and perhaps you might have gathered is, speak for yourself, if you think about it, that's all YOU really know for sure. Yep, I'm part of the "little guy" but I can speak for myself, I don't need you to be my spokes person. As far as the (bitcoin) white papers goes (an nope I haven't read it, doubt if I really ever will because it is what it is, it's not law), this is the "wild west" if you have noticed by now. the "bitcoin" algorithm is for all but that doesn't mean "Bitcoin" is.

I don't write well but I'm hoping you get the jest of what I'm saying.

Does anyone remember how many SP30s have been sold so we could roughly estimate how much hashing power they will add to the network in August?

I've read the bitcoin whitepaper and I don't remember anything that says the point of bitcoin mining is so anyone with electricity can make a profit.

The beautiful thing about bitcoin mining is that the rewards scale perfectly linearly. If a big miner wants to mine 10x more bitcoin than I do, they need to have 10x as much hashrate (I'm ignoring variance and pool fees for simplicity).

I often hear people say that the small miner is at a disadvantage, but honestly, I don't see that at all provided the small miner has low power costs and can get hardware for a small premium over production and engineering costs. Mining hardware manufacturers need to make a profit to stay viable.

I think it actually gets much harder for the big guys to scale after a certain point. It's not easy to get access to facilities that have the capacity to run and cool megawatts worth of mining equipment.

I don't think Spondoolies or Bitmain are making huge profits on the S3 or SP30 given the cost to engineer, produce, and ship these miners all over the world.

Whoa! I take a week or so off from Bitcointalk and come back to bad news about the SP30.  Sad

On the positive side, it is great to see Spond handling themselves professionally, as usual. Thanks for keeping the communication open and honest.

Looking forward to hearing more about the compensation options.
You're funny  Grin
