Re: ANTMINER S4 Discussion and Support Thread

Hi Everyone,

I think my S4 PSU died this morning, I have only had the machine 3 months or so and i think the psu is dead, could anybody help me figure out if it is and how i go about replacing the PSU

I woke up this morning to find one breaker on my board had tripped, I checked the S4 and the PSU doesnt show any signs of life at all, I have checked the fuse and thats ok, but the psu does not boot at all, is there anything i can do to fault find.

I know i had one of the newer PSUs that didnt have the issue the first batch did, and the S4 has been running flawlessly since i purchased it, just a bit depressing to see one of my best machines go down Sad

Any help would be really appreciated.

My 2-cents is to get an IBM 2kw PSU (208-240v only) and breakout board to replace it. http://www.gekkoscience.com/products/IBM2K_board.html is a good source for the breakouts and PSU's or check eBay for the PSU's. Together they should run around $75-80 total+ shipping.
I got 4 of the beasts for when my S4's croak...

That's exactly what I'm doing with my 5 S4s, it's definitely the way to go.

Anyone know if this would work for an S2 as well?

Certainly though is hefty overkill for the S2 as they 'only' pull a hair over 1kw. If you have >208v for feed then the HP 1200w CS (Common Slot) supplies would be a better match. Just have to do some soldering with those tp attach the PCIe power leads as breakout boards are not easy to find.
