Im still dying to find out of this is a single huge die or a multi die package. If knc wont tell us, who will be the hero to peel off the heatspreader first ?

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.

GOD GOD GOD please you all get some help somewhere!!!!   you are sadder than cancer ridden victims whose kids been killed by drunk drivers!!!

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.

according Jupiter launch video they started shipping yesterday.

I don't think they will ship for at least a few more days, maybe a 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...

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

What's his deal?  I'm just upset with the whole vendor why hw hate? Thread he puts up Then he turns around and hates on them.

Actually with pencil mod / changing R01F resistor, you can get atleast 30% more hashrate from the unit.

all gmaxwell's fault

The Jupiter show in the video stops hashing, I wonder what's going on. I expect news soon.
