I'm also pretty encouraged about the S3, looks like it could be a fun piece of hardware. I don't recall the specs exactly but it was something around 400W?

Power Supply: 4 +12V DC input, PCI-e connectors
That is what they say, I assume that means there will be connectors for wires and not just PCI-e connectors, maybe better to wait and see what it looks like..

@sidehack: Sir: Im trying to make this work: Do you think a few PCI-E breakouts / adapters off the existing motherboard ATX connector and various other connectors will work? Anyone every tried using one of these server backplanes out of the DELL server? It was pretty cheap compared to one of the 12V breakout boards and cables set. Plus this powers both PSUs, only one needed. I think I got it for $15 on Ebay. If I got the full 700W each out of them, how many S3 miners do you think you can run with the two? These were 2850 PSUs

Hi, nice work can you say me if your breakout bord is compatible with Dell 2850 power supply (NPS-700AB) ? thanks Matthieu

thanks
is it possible to have schematics to adapt your good work for Dell 2850 PSU ?

Are you asking if you can modify one of the 2950 boards for a 2850? It's technically possible but it'd actually be easier to start over from zero because even the pin spacing on the connectors is different.

I know pin are different but I'm not able to realize a product as yours. All on you product is good with IO header etc ...
So I'm able to translate your schematics originally for D750 to NPS-700 but not to create a totally new one

Two alternative setups for the gigampz DPS800 boards: you can fit 2 16awg wires per terminal if you need to balance larger loads. I sell both the 6" 18awg splitters and 24" 16awg leads in my signature link. I imagine that the D750 boards would behave the same way This is what happens when you use adapters with thin wires unable to carry a load. notice this is an 8pin ATX to 6pin PCIe adapter that burnt up under 200w load, probably only a 22awg wire at best. it even melted into a nearby fan wire. notice the difference between the burnt-out adapter and the 18awg y-splitter I sell. There is also a 16awg tip from the 24" cable visible, which is a little bit thicker again.

I don't sell anything under 16AWG. I've pulled 27A per cable before with no issues - certainly don't recommend that for extended periods but they can do it. The $55 kit comes with 4 16AWG 18" 6-pin cables.

I've picked up 7 of these boards - and I have to say - I'm dumb founded. Most of these 750 supplies can consistently pull 800 to 850 from the wall and not even blink. Sure they are loud when you turn the fan up, but the screw terminals mean infinite wiring options for any type of device whether it is PCI-e or not. Just wanted to say - I'm thrilled with them.

A supply rated for 750 Watts running at full load is expected to pull more than 750 Watts at the wall by 10-20% depending on the efficiency. The 750 Watt rating is for the output power.

The overcurrent protection in the supply trips out typically around 76 to 80A. I've taken them up that far using a dummy load through one of our boards. Not sure how well they'll sustain that power, but we've had customers reporting running upward of 800W sustained without any problems.

We've still got some of these for sale. They've been moving a bit more lately, looks like folks are picking them up to run S3s and RKBoxes and such.
We're looking at building another batch with a feature-stripped option, basically just breakout and basic controls (on/off, internal fan speed, EON, current share) but no 5V rail, no current sense, stuff like that. We'd still have full-feature boards available but also stocking the basic boards, which would probably sell for about $25 apiece.

Too risk to power 5 oced S3s on 3 of those PSUs (load Balanced) ?

Three of these would get you at least 2300W without issue, so if your S3 pulls less than about 460W overclocked (recall that's DC power, not from-the-wall) you should be fine. I had five overclocked S1 parked on three of these for a couple months with exactly zero problems.

Same here. Have 5 OC'd S1's running on 3 of these PSU's load balanced with no issues. I am going to sell the S1's and put the 5 S3's I bought on these PSU's.
