My guess would be they are debugging it. They should be just getting opened up about now.

well considering its 9am there i am sure they are going crazy on packaging boxes getting ready to ship. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

Let's cool down.. I came here to ruin the fun. Bitfury chips are 55nm and do <0.7 W/Gh. KNCMiner chips are reportedly >1.4W/Gh.
I'm just wondering as I really have no idea, how much would an equivalent miner (in terms of GH/s) from Bitfury cost? $8000 for 400GH/s October delivery. With 'pencil mod' you can get over 500GH/s. Actually with pencil mod / changing R01F resistor, you can get atleast 30% more hashrate from the unit. The old pencil rubbing trick, I used it couple times this month I already bought myself couple boxes of HB pencils... Gonna be rubbing pencils all over my jupiter... wow another 30% increase for a wopping 780GH/s /joke

These are my numbers for a Jupiter assuming 550GH, no pool fees and 100% uptime. Also original investment of 66BTC PSU+VAT+Shipping (might be less for some), for the next 13 difficulty adjustments (~6 months), assuming you start hashing in 2 days. In my Spanish excel "," equals "." and dates are in this format "day/month/year" The % increase per difficulty adjustments I obviously pulled out of my ass, but I think they are consistent with the "several thousand" machines that KNC claim to have already sold, the 500TH friedcat announced for October and bitfurys. I think Hashrate will climb fast to around 3PH and then % increases will slow down, notice how by the beginning of next year we will be aroud 7PH which I think is very plausible.The break even line is original investment+operating costs. It looks tight. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FK4GQlCL.jpg&t=665&c=wgAK-NRScCod3A)

Heat is cost also, please read my post.
I read your post it is nonsense. The fan on a power supply even at 100% in inaudible over the over all the other system cooling fans (like on a Jupiter means 6 140mm fans). Having run a 48 GPU farm for 18 months I can say from experience it is a non issue. The efficiency curve is essentially flat for modern PSU from 20% to 100% load. If an 850W unit is 95% load (your numbers) that means the load is 807W. 70% load would require a >1150W PSU. Where is there an 1150W PSU from equal or better brand for $30 more? It doesn't exist. Under what conditions would that save $120 annually? It also doesn't exist. You underestimate the cost of a larger PSU and overstate the benefits. Even if you add in the cooling costs and assume low efficiency AC 100% of the year you still don't get $120 in saved energy from going with a larger PSU. So your $30 increased cost is nonsense and your $120 annual savings are also nonsense. So one last time your post is nonsense. Sure one "could" spend $100 more for a 1200W Platinum PSU and it would marginally reduce their operating costs. However the increased up front cost and the small gain would make the break even point something like 3 to 5 years. Nothing wrong with doing that but it doesn't mean that going with a smaller gold PSU is a bad idea either. What an elegant smack down. Congratulations and thanks for sharing something that many people are not yet aware of (due to old beliefs). These new power supplies are indeed pretty flat from 20%-100% load. And upgrading costs way more than it saves (and in addition you are essentially wasting energy in that process anyway). Lastly, I've been looking into PS that do well at lower than 20% as I only have 100W or so to power. The Super Flower Golden Green 400 is near the top, especially in that it is cheaper than the next two. And a new PS Coolermaster, the V550S is even better, hitting 88% at 40-45w, 91% at 60-66w and 92% at 80-87w. The new Corsair RM450 is another nice one. Hope that helped someone. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Congrats to KNC Miner. Hopefully they get things going this week.

I will be really pissed if my order gets sent tomorrow instead of today. Germany has a holiday on Thursday, so Express shipping costs would have been wasted and I would have to wait a day longer when everyone is happily hashing away... ![Angry](https://bitcointalk.org/Smileys/default/angry.gif)

They just got the chips apparently. I don't think they will ship for at least a few more days, maybe a week.

I think it will come down to how well hashfast does and if they stick to their delivery in ~3 weeks. I'm optimistic I'll make back my cost (60ish BTC) or at least +/- 15% from it. Which isn't bad considering a few days ago it seemed rather possible things might go much worse for us. Also excellent job to KNC. Whether the machines ROI or not as long as they are shipped relatively soon they can relax knowing they delivered on their promises to customers (late delivery easily compensated by increase in hash rate in my opinion). I'll be keeping a close eye on what they cook up for gen 2 for sure.

Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:)

Nothing wrong with doing that but it doesn't mean that going with a smaller gold PSU is a bad idea either. Newegg, Coolermaster Silver 850 169$ Gold 1kw 216 Gold 1.2 kw 249 Why you mention platinum? To fit your post? Please calculate it again using real prices. Consider that i was answering about knc buy for datacenter, large operation For you having exaust temp 59 instead of 45 is not a problem but for ac costs it matters Think about margin to overclocking and stable voltage, also psu on 70% load mtbf will be much higher. On large operation replacing psus, downtimes are labour cost, downtime costs. Ok so is 40$ worth to save ? No. Maybe for you, ok.
