PSU should operate at 60-80% to get maximum effeciency and cool

The difference between 50% load and 100% load on most modern 80 Plus Gold PSU is about 1%.

So 1% of 850W = 8.5W.   That is about 74 kWh per year.   At $0.10 per kWh it is a grand savings of $7.40.

have you accounted heat cost and noise ?
1% is not true

70% load 91% eff, temp 45c
95% load 88% eff, temp 59c

read review, please Smiley

you save 30$ usd on psu and take loss 120$ usd per year or more

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=350

Ok so 3% = 25 W.  Not sure how you got a bogus $120 per year or more out of that.  If your power costs that much then you have no hope of making a profit no matter what PSU you use.

Heat is cost also, please read my post.

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.

I was surprised the wagers were still roughly right before betting closed. I guess some people really wanted to believe.

I was surprised that people would gamble perfectly good BTC on such nonsense! They obviously don't need miners if they have BTC to throw away.

First of all, as I've doubted KnC will accomplish this I must say: Congratulations KnC. If somebody told me this morning they will produce fully working prototype by sundown I would think he is on drugs. Thought KnC were slackers, turned out they were tight as a drum. To manage to do this in a single day shows they were fully prepared, when they got a chance to walk the walk they did it. They haven't over-delivered, but considering machine has 25% hash-rate increase compensating eventual 25% difficulty increase caused by being late you can say they simply delivered.


What you meant to say was that you are terrible in evaluating investments..  that's ok, you probably have a BFL order clouding your brain and storming your butt

So they are almost up to 1/3 of a bitcoin already.

I call dibs on the first 1BTC mined on a jupiter!!

My BTC address is below KNC, thanks in advance Grin  Wink  Grin

Thank god (for us who bet they'll fail) they haven't done this on Friday, cause we would lose the bet. You can say bitbet resolving to "No" leaves, in the end, everyone happy: Us for winning the bet and KnC customers getting their machines soon. Good job KnC!

Indeed. But the next diff will be approx 30% higher and you don't have your miner yet. You'll start (at best) at 30% lower than today.

It's a race condition: if they can make the chips work 30% faster before the next diff change and you get you miner in the meantime, you won't have lost revenue (grossly). If they fail, you will be worse off.

Maybe next time they'll know better than making claims they can't keep.
What are you talking about, every calculator I have seen says the Oct delivery KNCminer is going to pay for itself.



I said you will make less than if it were shipped on time, unless they made them fast enough to cancel out the difference in difficulty. I was not trying to divine the possibility of you making break-even or positive ROI.

If I recall, they said they'd ship in the summer, then pushed it back to August, then to September and now October.

I have a feeling the little miners have just been screwed by this release. The amount of hashing power coming from this is going to make what is already out there insignificant. The unprofitable miners will see what little they are making dry up. People who spend hundreds because they can't afford to spend thousands have just lost everything. When two machines produce over 1 terahash... Gigahash has just become unimportant. I hope the pools can support all this hashing power.

This release is a significant game changer. I think that the Hobby aspect is going to disappear. Tongue

Hashrate is about to double. That makes a 600GH/s miner then as fast (profitable) as a 300GH/s miner now. Fun times!

The real story here isn't "ROI or no ROI?  Ship 9/30 or 10/3?"  The celebration and the sour grapes, the sore losers and the ecstatic supporters, the assholes and the gentlemen, that's all fun to read.  But IMO opinion that's not the story.

The real story is the presentation of a functioning IC entailing leading edge technology in a period of time far less than they'll teach you in school is even feasible.  

Every time some information came out, it was met with armchair experts who pontificated on the folly of it all.  It's all in the 600+ pages of this thread:  "The package is ridiculously large; OrSoC must be idiots."  "The power consumption will be way off the scale."  "They can't come to market without the test sequence. It's going to be a disaster of BFL proportions."  "They're too small to produce in size."  Best of all:  they're Swedish, how can they possibly do high tech?

Spending a significant part of my life in venture capital analysis, I have to say:  while there were no red flags for me from a business or technical standpoint, I didn't think it would happen this close to schedule; too many moving parts and supply chain issues to be certain.  

There are still red flags, I'd say, in both CoinTerra and HashFast, but I'm not going to discuss them.  They will be what they will be.  Instead, I'm just sayin' to KnC's professionals:

Spectacular performance!
