This is sad even at almost $400/bitcoin you barley make anything, completely retarded to buy any of these overpriced pieces of shit.
WHAT? You must be doing something wrong then.... Ive been hashing the 3 saturns since september 15th,*edit.. (one on the 11th, two on the 18th)which is just over three weeks, and they have Produced enough BTC to buy 2 Nov. Jupiters, which is about 150% more hashpower than I currently have...IF they are still 550GH/s devices... which I'm sure they won't be. If you can get more hashpower than the diff increase, your income will grow instead of diminish.... I still have a week left to hit the one month mark, which is about how long it has been taking for the diff to double... and right now, the diff increase is stalled! So I am Way ahead of the game so far IMHO. Out of curiosity, have you sold every bitcoin you mined pretty much instantly at whatever the price that day, or is your revenue still in BTC and its dollar value purely theoretical, based on current/future BTC exchange rate?

You are mistaken. Highest efficiency is at 50% load. At one time the efficiency curve was very "curvy" but those days have been gone for a long time. Today the efficiency curve is very flat the difference between 50% load and 80% load is usually 1% to 2%. So buying a super sized power supply to run it at 50% load would save you a whole 1% * 600W * 24 * 365 / 1000 = 52 kWh. At $0.10 electrical rate the savings would be a staggering $5.20 a year. Now if you spend $100 more for this larger "have to run at 50% load because some article in 1998 said that" power supply your break even point is roughly 18 years of continual usage.

I assure you 80% is correct. You may read many reviews of X number of PSUs and you will get a picture that PSUs are most efficient between 50 -70%. The problem is that these review sites rarely if ever leave the PSU running for 3 or 4 hours. If you are lucky enough to find a psu review that does test after a long period of time you will see that 80% is the sweet spot on most modern & high quality PSUs.
If you can send me a link that proves otherwise i would love to read it.
Nope. He is right the curve tends to peak around 50% (but it is still foolish to aim for that). You can check the official curves here. http://www.plugloadsolutions.com/80pluspowersupplies.aspxAlso I think if you recheck those reviews you will find they don't show a peak at 80%. The point is that the curves today are very flat there is no reason super-duper oversizing a PSU (and pay $100 to $150 more) to gain 1% to 2% higher efficiency. See post above for more. Of course the "has to be 50%" myth will never die. At one time it did make sense because the efficiency at 50% load might be 85% and the efficiency at 80% load was a horrible 68% but those days haven't existed for more than a decade.

butterfly monarch is better have 600 Ghs is more cheap
knc is litle expensive for the difficulty that we have
cointerra also cheap and more powerfull
Hagaha , do you live in a dreamworld or is this youre first day in bitcoin world. BFL only produces shit and expensive toasters. Cointerra, who knows, but they are already way behind schedule. Knc was just a week of with first deliverys and roi has turned out great for me. Btc mined already more then the jupi cost me with the btc price of yesterday before the big drop.

Did you read what you quoted. ~Yes 50% is the peak efficiency but it isn't like a 1250W PSU has the same cost as a 850W one. If choosing an oversized PSU costs you $100 upfront and saves you $5 per year it doesn't make it "super win". Not saying it is "bad" but it isn't "bad" to aim for something more economical either. Hint: KNC uses 850W PSUs. What really matters is lifecycle cost. Lifetime hardware cost + lifetime energy cost + lifetime cooling cost. As a though excercise say KNC sorted their chips and took the highest efficiency ones and packaged them into a "Super Jupiter". The Super Jupiter would get 2% higher hashrate and use 2% less electricity however it costs 100% more than a "normal Jupiter". Would you buy one? Me I probably would just buy two normal Jupiters and get double the hashrate for marginally higher energy cost.

Unicorn powered mining machines might be cheaper and better - only problem is that I can't order one and expect to receive it in 30 days, just the same as the BFL Monarch!

Wow HelMax, You sure are "Green" on mining! If you are eager to waste money, BFL is sure the place to go, they have a proven track record of delivering a year to 8 months late. Good Luck. PS Is there a cointerra being delivered I missed? I thought they were late as well....?

Yup. I just tend towards larger PSUs.. because why pay for a smaller one when you might need a larger one? Its not like you cant use a larger PSU for a smaller project... but you cant go the other direction.

I have 2.5 THs mining rig ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) maybe i dont 1) They have never provided hard sales figures. 2) Why would any ASIC company lie to overstate pre-sales UPWARDS? Imagine the CEO of KNC came out today and said "we have already sold 5 PH/s worth of rigs for November and still have another 5 PH/s available" What do you think that would do to future sales? What do you think that would do to refunds? If anything, all ASIC vendors have been rather coy about how much capacity they have sold because they ALL know the more capacity sold the less they are going to be able to charge for "the next rig". With delivered units customers can see it in the hashrate but for undelivered units no company wants customers to know the "truth" if the truth means they won't be able to sell more of those rigs they are continually building. TL/DR: the best conspiracy theories are ones which at least have a glimmer of rational thought.
