That would make sense but why does it say 4x6pin PCI required? maybe a typo edit. S3 Specs Effective Hash Rate: 504 GH/s±5% Power Consumption: 390 W on wall Power Supply: 4 +12V DC input, PCI-e connectors
Engineered safety margin. Standard 6-pin molex connector is rated at 8A per pin, so 288 AW per connector. Usually if you're running 24/7 you de-rate by 80% giving an upper bound of 230W @12V. Given the S3 design uses 390W stock, it leaves a headroom of 35W @12V per blade which isn't a lot if you're trying to give the end-user some room to overclock and err on the side of safety. So four 6-pin PCI-E plugs gives you ample room to overclock without worry about burning out molex connectors.

Maybe they are mining on them for a week, then pass the savings onto us?? Well I bet in a week bitcoin prices are back up a bit after the US marshall auction fiasco so they would be cheaper BTC. Also the rocket boxes are delayed to the same day, the 27th, however the rocket box does not come with a controller (Raspberry Pi ) and the S3 does. The S3 is faster hashing too. I can trust the S3 already because of the track record with the S2. I will wait patiently. Where did you read about a RPi on the S3? Since they may also have an upgrade path for the S1, I would think the easiest way would be to continue to use the OpenWrt controller board as the S1's have. The only reason I'd prefer those crappy little controllers is they don't chew up SD cards like RPIs can/do. In a perfect world I'd much prefer something with embedded flash storage, either a custom design ($$) or maybe a beaglebone black.

This is much better design than ≥400W in Neptune "cube" in KnC design. Well, they blow air at plastic connectors, but still...

So four 6-pin PCI-E plugs gives you ample room to overclock without worry about burning out molex connectors. Yeah, there's a bunch of factors that they'd have to consider. The "standard" molex minifit jr pin is currently rated at 9A, (IIRC the first series were rated at 4A/P, the baseline has been increasing steadily since they were introduced years ago). That said, there's no telling which pins would be used in the connector, they could instead use the top of the line molex pins (13A/pin) or cheap knockoffs (??/pin). Then there's the quality of the connecting cables used, which can't really be planned for aside from setting the bar very low.

So I guess we are all waiting while they "test" the new gear. They only delay comes from the fact they want to make more BTC while they have probable cause to.

S3 Specs
Effective Hash Rate: 504 GH/s±5% Power Consumption: 390 W on wall Power Supply: 4 +12V DC input, PCI-e connectors Power Efficiency: 0.77 J/GH on wall Size: 331 mm x 137 mm x 160 mm (Dual blades assembled inside a box, including the fans) Fans: Two 14038 fans mounted on both front and back ends.) Operating Temperature: 0 °C to 35 °C Complied with: FCC / CE Network Connection: Ethernet
The above descriptions and specs are projected number and subjected to change before the sales open. The main reason may be for FCC/CE certification may require some margin of additional safety. With Overkilling/Marginal Safety FCC/CE certification may not be possible.

It was a typo, thanks.

Buy high-quality class 10 cards (I prefer Patriot brand) and you will have far fewer problems.

The keying is to prevent issues with existing equipment which used the same connector series but with different pinouts and/or voltage levels. There are no differences aside from that (assuming you're comparing similar grades of parts).

Aren't patriot about the cheapest cards you can buy?

Buy a s2 for 1400 or wait for s3's?
well its ur choice... i think bitmain will delay S3 again it just too good to be true, 4 PCI-E but only 390w even if so... s3 wont be that cheap... i assume its around 1btc - 1.5btc new generation, but cheaper? re u kidding me? S3 has got to be cheaper than old S2 in $/Gh S2 can be had for $1450 for 1000Gh so S3 must be less than $725 for 500Gh yeppp, you tell me about these 4 PCI-E but only draw 390w too good to be true, but if so, it'll be really perfect

im using 700w cougar PSUs that have 2 PCI-e cables with the 'extra' PCI-e connector (ie 2 x 1+ 'extra' 1)
i would imagine in this case using the 'extra' connectors would be ok?
i tried using the same 'extra' connector on a 550w PSU when i got my first S1 but it melted the 'extra' connectors wires in a matter of minutes
then, bitmain will suggest us to buy a new PSU... PSU with 4 or more PCI-E cables

then, bitmain will suggest us to buy a new PSU... PSU with 4 or more PCI-E cables If your psu can supply the S1 @ 380w, then the S3 @ 390w should work as well. Remember your 'good quality' psu only works 24/7 at 80% of its rated load, cheapo's are less. Overclocking will be a different situation, read the label on the box, then "Do the maths". If your server room is too hot, then even good psu units will overheat/fail.

Estimated Next Difficulty: 16,847,110,142 (+25.14%) With this in mind lets hope the S3 can start at under 1btc, otherwise ROI is unlikely.
