Hmm. If it did 570Gh with 850W@wall maybe it could do (1.15*570) well over 650Gh with a 1000w PSU ?

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

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

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.

Have you seen this bullshit. First prototype/finished miner of the production line and they are been accused of stealing customers ROI etc.

I just got home after a long drive. Best news ever!

Do you have your knc in hand?

I hope that, several shareholders are in a groupbuy running by blastbob xD

Safe answer.. They will be hashing in the end of this week

I dont really care to much about the end of september date. I still have BFL equipment on wait. Who cares about "1 week"

I will be bringing the 1500w PSU to see if it can do some good

[itod]

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.

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!

Heat is cost also, please read my post.

[DeathAndTaxes]

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.

And the bitbet is now over.

Gratz to all who won their bet!

[demonmaestro]

so just wondering what if i went and got a corsair ax760 for a mercury miner. overkill? waisting money for platinum cert? Its all digital...

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.

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

I wanted to say exactly what I've said. Too bad you can not dig it.

What? Why post this crap?

[KS]

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.

[Aggrophobia]

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