This is not true. If power is limited, buy more SP20

1x SP20 1000GH/s 0.45W/GHs Can the S5 do this? No.

What you never want to ROI? Seems to me unless you have expensive power SP20 should be ran hard (1.4-1.6TH) to make up for the initial investment.

I think the beauty of the S5 is its pretty much the SAME efficiency @ 1.1 or 1.3TH. So run a S5 @ 1.3TH with 650W then compare that to 950W required to get an SP20 to say 1.4TH give or take.

The SP20 can be downclocked to be more efficient sure but I have both the S5 and SP20 and at this point I'm more impressed with the S5. Simply because I see that roughly 0.5GH/W efficiency @ 1.3TH, which maximizes my return without losing 25-30% of the hashrate just to meet some arbitrary W/GH goal (which varies greatly depending on location overhead and power costs so YMMV of course, to each their own).

You are using the bulk 15 unit price by SPT. I'm sure if you PM Bitmain, they will come up with a discount bulk price for 30 units the same way they come up with a bulk price for 52 units AND offer free shipping or discounted shipping. So, just because SPT has a quoted bulk price FOR 15 UNITS does not mean Bitmain will not do a bulk price for 15 or even 30 units.

See what I'm saying?

I do agree with you for the under clocking of the SP20 to the same efficiency as the S5. However, do not assume Bitmain will not give a discount on shipping or no shipping costs for 30 units. That's all I'm saying. Just because SPT actually lists their bulk price with shipping costs ($0.00) for 15 units does not mean Bitmain would do similar with 15 or 30 units.

Yeah, just going by the 18kW limit posed by the question. Tupsu touched on this already, but even in qty 52 Bitmain is still charging $351 per unit, or $376.03 per unit shipped to the US. You'd only be able to use one coupon though, so if you had 30+ coupons you actually wouldn't save anything ordering 52. You might be able to swing a better deal than the single price, but I'm not sure Bitmain would give you a better price on 30 than they offer on 52.

nearly 300 kw / 30EUR per month, But only produces 0.0122 x 0.45x 30=0.165BTC per month

.165BTC = 38EUR, so the additional income more than makes up for the additional power draw.

If limited to 18,000 watts, one can obtain more hashing power with the S5 versus the SP20.

One single SP20 @ $479.00 without shipping [1,700 GH/s @ 1200 watts = .705 watts per GH]
One single S5 @ $370.00 without shipping [1,155 GH/s @ 590 watts = .510 watts per GH]

Let's say power limitations at your location is 18,000 watts:

18,000 watts / 1,200 watts = 15 SP20's x 1,700 GH/s = 25,500 GH/s (25.5 TH/s)
18,000 watts / 590 watts = 30 S5's x 1,155 GH/s = 34,650 GH/s (34.65 TH/s)

Without going any further with comparisons on ROI, one can easily conclude the S5 is easier to achieve ROI than an SP20. This is based off the price of one single unit. If one wishes to compare based on bulk pricing, they must use both bulk package prices [SPT's 15 x SP20's versus BITMAIN's 52 x S5's]. Even if one wishes to choose the bulk price of 15 x SP20's versus the price of one S5, it would still be more worth while to get the S5 at this point in time. The main reason why it would be worth it IS TO KEEP FROM LIMITING THE AMOUNT OF HASHING POWER I CAN HAVE WITH THE LIMITED AMOUNT OF WATTS AVAILABLE TO MINE.

If limited to 18,000 watts you will have approximately 36% more hashing power with the S5.

Just saying...

This is not true. If power is limited, buy more SP20

1x SP20 1000GH/s 0.45W/GHs Can the S5 do this? No.

I am happy that I bought 2015-01-26 at night three S5 for 3.983 BTC ( Today it costs 4.894 BTC)

But I bought later on the same day 3x SP20 for 3.954 BTC , and it was a much better deal. 1BTC=303USD

3x SP20 3 TH/s 0.45W/GHs total 1350W

3 x S5 3,45TH/s 0.51WGH/s total 1750 W
450GH/s more costs me every hour extra 400W

nearly 300 kw / 30EUR per month, But only produces 0.0122 x 0.45x 30=0.165BTC per month

If you're talking about 18,000W and 15 SP20s, why are you quoting the single unit price on the SP20? 15 SP20s cost $5500 shipped, which is a considerably better price.
Downclocked to the same speed as an S5, the SP20 is as efficient or moreso that an S5 (neither of mine hit .510 J/GH on a Platinum supply, BTW), and the price is close to the same.

30 SP20s will set you back $10,990 shipping included, while 30 S5s will cost $11,100 plus shipping (~$11,900 shipped to the US). If you have 30 coupons you could probably knock $1000 off that price, but that just makes it a wash.

Owning both, if I had 18,000W to play with and had to choose between the SP20 and S5 at the same price, power and hashrate I'd definitely go with the SP20. Either would work, but arranging that many would be nicer with the SP20 and it just feels like a much more rugged unit.

And when doing profit calcs, don't put the SP20 at 1.7 TH/s. Most people get about 1.6 TH/s out of it, almost no one gets 1.7 TH/s. Whereas the S5 is easily overclocked to 1.3 TH/s from virtually every unit.

Yeah, mine won't get to 1700GH/s regardless of cooling. 1650 is fine, though I only run mine at ~1250 to maximize profits. Overclocking the S5 is a little more variable, as it somewhat depends on your PSU. The difference between 11.9 vs 12.3V in negligible on the SP20, but it actually has a decent impact on both overclocking room and efficiency on the S5.

What kind of power supplies are you using where you can adjust the 12v line?

I generally use server supplies, but even different models of ATX PSUs (or sometimes even different units in the same model) can have different "12V" outputs. The ATX spec is actually +11.40 V to +12.60 V. Especially with big crossloads (IE using only 12V and nothing from 5V or 3.3V) different PSUs can range anywhere from 11.8V under full load to 12.2V or so, even without purposefully adjusting them. If you have one feeding an S5 at 11.8V and one at 12.2V, you could see a 6-7% difference in power consumption just from the extra voltage.

Another excellent point to make and it's doing so while having more power efficiency than the SP20.

And the sp20 vs s5

cost of SP20 = 0.28$/GH
cost of S5 = 0.32$/GH

that a 13.33% difference

but the SP uses 32% more power

so at .10$ per Kilo gh for gh it would cost you .53$ per day more to run a Sp20 instead of a S5

it would take you 84 days to catch up to the price of a SP 20 ( again this is gh to gh compare ) using a S5 with better power

So Bottom line, If you Keep Your S5 longer than 3 months, Better to Buy a S5
If you don`t think it will ROI in that time or no longer worth mining with them and sell them Before
Get a SP 20.

If you are Upset at BITMain like me, Boycot them and Buy the SP20 like i have done even tought i keep them longer than 3 months

Bitcoin price goes up from $200->230: S5 price goes from $310 to $341 (~1.2->1.48BTC)
Bitcoin price goes from $230->$280: S5 price goes from $341 to $370 (~1.22->1.32 BTC)
Bitcoin price drops from $280->245: S5 price stays at $370 (1.47 BTC)

seems they want to price in BTC but adjust the USD price manually. Not sure why they do that, as right now an SP20 is about the same 1.6BTC (shipped) which is pretty damn competitive for a cleanly-made, sealed unit with adjustable speed and fans

I can give then the first jump in price, but they did the second one too quickly. I would think the sales have really gotten slow.

I don't think they are bothered as the are preparing the S5 for hashnest. The S5s are probably already mining there. They were selling S4 converted to hashrate and the last I look, there was 460+ units (I think) of S4 left and suddenly sold out....

You've seen what happens when the price changes once while someone is mentally locked into buying, imagine what would happen if that price kept changing every 2 minutes?

Bitcoin price goes up from $200->230: S5 price goes from $310 to $341 (~1.2->1.48BTC)
Bitcoin price goes from $230->$280: S5 price goes from $341 to $370 (~1.22->1.32 BTC)
Bitcoin price drops from $280->245: S5 price stays at $370 (1.47 BTC)

seems they want to price in BTC but adjust the USD price manually. Not sure why they do that, as right now an SP20 is about the same 1.6BTC (shipped) which is pretty damn competitive for a cleanly-made, sealed unit with adjustable speed and fans

I can give then the first jump in price, but they did the second one too quickly. I would think the sales have really gotten slow.
