Today we can reveal that our maximal power consumption will be below 1.6 W/GH/s.
KNC, Can you clarify what the 1.6 J/GH represents Is it "at the wall" (assuming 90% efficient ATX PSU)? i.e. whole system 625W @ 120Vac for Jupiter (400 GH/s nominal) 625W / 400 GH/s = 1.6 J/GH "at the wall"Is it the entire system DC load (everything but ATX PSU inefficiency, 90% assumed) i.e. whole system 625W DC load ~= 711W @ 120 Vac 711W /400GH/s = 1.8 J/GH "at the wall"Is it just the asic boards (fans additional)? i.e. 625W asic boards + ~60W for cooling = 685W @ 12Vdc ~= 761W @ 120 Vac 761 / 400 GH/s = 1.9 J/GHOn edit: the word "all components would seem to exclude the third option. I would like to update the electrical break even point for KNC miners. https://bitcointalk.org/index.php?topic=281279Oh and if you are willing to provide an estimate of total pre-orders I wouldn't complain. https://bitcointalk.org/index.php?topic=278384

looks like I chose just the right ones... got my 3 CX600 ATX's weeks ago for the Saturns, and since "Builder's series... already has the 6-pin pci-e plugs on each power-leg, it won't require adapters. Sweet. The Q for most now is...can you get them before supplies are short online? Happy shopping...

... Ah now I can fix this based on KnCs latest 1.6W/GH announcement
75/10GH = 7.5W/GH 640/400 = 1.6W/GH 7.5/1.6 = 4.68x More Power Consumption (Guaranteed)
Monthly electricity bill for KNC blade (overclocked)? Less than *half a pack* of smokes in NYC. Ten cigarettes. A month. Thanks for the math. KnC Blade? What is that! Something new? Time to buy! But seriously I understand Electricity Costs are null right now, but once(If) these machines ever ROI, By that time BTC mined will come much closer to Electricity Cost and we can estimate the longevity of these machines until they literally make less BTC than they consume in Electric Cost. Yep, meant Asicminer , and they're selling -- friedcat plays it consistently well. My hat's off to him -- from quick & dirty chips to solid marketing. The only bawwing in his threads is his constantly dropping prices. Which is pretty lulzy, if you think about it

"We recommend a 600 Watt PSU with a minimum of 2x PCI-E adaptors for our Saturn model."
Hi, can somebody please explain what exactly PSU adaptors used for PCI-E?

PCI-E plugs are either 6 or 8 pin plugs. You can tell which they are because the wires are yellow and black only.

OK, thank you! So it's simply those adaptors that used for video cards.

That Enermax only has 2 PCI-E connectors according to the cables tab on the website. Jupiter requires 4. I'm not sure which PSUs supply 4 PCI-E connectors, unless we'd have to use adapters.

Each cable looks like this. There are four of them. The linked supply has 8 PCIe connectors total. 8 PCIe connectors is actually optimal because while Jupiter only needs 4 connectors and the connector can handle 300W+ there is no easy way to know if a PSU with only 4 connector is designed to deliver that much current on the wire safely. By the spec a PSU only needs to deliver 75W to each 6pin connector and 150W to each 8pin connector and be compliant. Most PSU with only 4 connectors are probably fine but there is no good way other than testing to know for sure. The nice thing about a PSU like this (or any PSU with 8 connectors on 4 sets of cables) is you know that it can safely deliver 300W (150W + 150W) on each set of wires.

So if 1.6.W/GHps is the max power usage, and 500W is still the max total power usage for the saturn, does that mean it might perform at as much as 312 GHps?

I am most concerned about how we will need to power the device on. Are we expected to do the paperclip trick? That would be good to know. There are adapters which have a switch if KNC isn't going to use the 24 pin connector. I have soldered plugs with the "power on" circuit permanently closed and I just buy PSU that have a mechanical switch on the back of PSU. Same thing as paper clip trick but a little more secure and convenient.
