Still have some 1100w w/ cables available? How much would it be needed for 2 S3's?
Yes. One 1100w and 4 cables will run two S3s. Shoot me a PM we'll work out the details.

Hi!
I need to replace an Antminer S4 PSU. Not sure if what you have available will do...
If yes, do I need to do any modification (i.e. soldering, etc.) to it?
Please let me know.
Thanks in advance,

Does your S4 use 12V lines straight to the hashing board, or does it use PCIe?
My PSUs won't fit perfectly into the case(standard 1U units vs that square thing Bitmain uses, if you get me measurements on the current PSU I can confirm fitment), and you'd need two of my 1100W units to do it. As long as that doesn't bother you, I bet we could could make something that would do the trick.

The units i received are purring and running at amazing efficiency, i am really satisfied!
Also quakerfiend420 has great post purchase support. Much love!

From looking @ the specs I see that the power supply supports load sharing, is there a power sharing wire/pin on the breakout board? Do you have a detailed Diagram of those additional pins on the breakout board? or can you point me to one?
Thanks
Thanks
It is not connected to a pin on the top side of the breakout board, but it is available where the 25 pin connector connects to the breakout board here:
You could pretty easily solder a wire to it and use it. According to the datasheet it should be pretty simple to enable sharing, you'd just need to connect that pin on all the supplies you're using, although I've never personally done it.:

The PFE front-ends have an active current share scheme implemented for V1. All the CS current share pins need to be interconnected in order to activate the sharing function. If a supply has an internal fault or is not turned on, it will disconnect its CS pin from the share bus. This will prevent dragging the output down (or up) in such cases. The current share function uses a digital bi-directional data exchange on a recessive bus configuration to transmit and receive current share information. The controller implements a Master/Slave current share function. The power supply providing the largest current among the group is automatically the Master. The other supplies will operate as Slaves and increase their output current to a value close to the Master by slightly increasing their output voltage. The voltage increase is limited to +250 mV. The standby output uses a passive current share method (droop output voltage characteristic).

Some more PSUs shipped, still have 1100s, no 1300s left.
July 09, 2015, 01:27:57 PM
Ah, its a shame you wont be getting more 1300s, one would be nice.
What's the expected lifetime on these?
What's the expected lifetime on these?
I've been running anywhere between 4 and 12(depending on what gear I have at the time) of the 1100s for over a year now with 0 failures. These are enterprise class PSUs, so MTBF should be quite high.
Very well, anyhow, i am not in the US but i will still PM you with details.
