Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[solteykr]

Definitely ouch.  Its very weird. my S9 has a AVR. but it still got burned. My pocket is hurting now.

[solteykr]

Your P/S is a brute. Short-Circuit protection should have kick-in and save the day.
A fuse should be mandatory in any high power design. In this case, miner.
Didn't see any so far, and many manufacturers out there. 
 

How do I add a fuse between the PSU and Miner? Do you know any electronics? How many ampere should I put? I have 3 S9's coming. I would like to protect it. Its very frustrating to see my investment just get burned. tsk.

Power supply is where you do not want to cheap out.  I learned that when investigating PSUs.  I ended up going with an EVGA 1600 T2 because of these vital components.  Not only are we talking about a $2000 computer, but potentially my house if a fire started.

Two of my S9 11.85TH 550M Hashboards.. My S9 pass through a 2000VA AVR. The Control board, Power Supply is still functioning. Why did it happened? Is it still repairable?

Are your guys S9's really just spontaneously catching fire??? Were they running too hot? Malfunction with the power supply? Anything other than they just randomly caught fire?

Simple equation is Power in watt ( P ) = Voltage ( V ) * Ampere ( A )
or
P = VA
or
A = P/V

1600W / 12 V = 133A

133A / 3 Boards = 44A

Rules of thumb you rate your fuse x2

80A Fuse with enough DC voltage rating will do a good job.

Need a breakout board and extra cables

I didn't fused mine. I use high quality EVGA 1300 supply with working protections.
Over-Voltage, Under-Voltage, Short Output, Over Temp, Good voltage regulation and 10years warranty.
Expensive but I sleep better.

For few extra bucks, manufacturer fail to add safety to save money.

My PSU is the Bitmain APW3+-12-1600W, It says it has every protection. but it failed. A waste of money.

points taken. I used Bitmain APW3+-12-1600W.

Will definitely do this. thanks for the info. Is a 1300w PSU enough to power the S9?

Will this do?

I use a combo
1x 1300W  -> Board 1 + 2
 and
1x 1000W -> Board 3 + Controller

Running on 220V.

1x 1300W won't be enough

Not the best of ideas to go with a power supply that is meant to be used in home computers, pushed not nearly as hard, for not nearly as long as you'll be using them for. Plus these are WAY cheaper.

Not only crap miners, but crap PSU's. Way to go Bitmain

Ah I just read this, it's the shit power supply Bitmain sells that fucked up, not the miners. I guess that's a relief that it's their psu's and not miners that are randomly catching fire lol. Makes sense I suppose.

Definitely go with some good server power supplies in the future.

Just *how* is an obvious failure of the hash board Vcore regulator  -- probably the MOSFET's shorting -- the fault of a PSU? Just what in a PSU do you assume could have prevented this?

The Bitmain PSU can supply up to 133A continuously and probably at least 10-15% more before tripping out, the combined maximum current rating of 3x PCIe connectors is only 81 amps. Vcore regulator blew, all power took the easiest path - through the short circuit - and so yes, the connectors and wiring smoked. For what it's worth, I have 25 of the AWP1300 supplies and have had ZERO problems with them. Don't know about the newer APW1300+ but the older ones are very well made.

Now should all miners have a fuse between the power sockets and Vcore? IMHO yes they should but that is just speaking as an Engineer with over 50 years of dealing with power electronics...

[solteykr]

I use a combo
1x 1300W  -> Board 1 + 2
 and
1x 1000W -> Board 3 + Controller

Running on 220V.

1x 1300W won't be enough

Will buy the 1600 instead? it will be enough i think?

They are $150-ish.  The EVGAs are $300 - $400.  I go higher end on those.  

Man, that really stinks.  I wonder what caused the problem.  Try calling the Colorado office for Bitmain warrenty at +1.844.248.6246???

Yes sir.. My power supply is still working with 12v.. that's odd. With your years experience in electronics. what can you suggest? Do I just put a 80a fuse between the power supply and miner? How do I put it? one fuse for the positive, and one fuse for the negative?  I have 3 more S9's coming nxtweek. I can surely have a super advice from you sir. Thanks.

I contacted their support, asked them why it happened, They said it was my PSU giving irregular voltage. They then asked me what PSU im using, I informed them its their Bitmain APW3+-12-1600W PSU. I'm waiting for a reply now.

[jamesb777]

The EVGA 1600s are rated for continuous loads so that's plenty.  I've read the reviews and the PSU can actually handle temporary peak loads up to 1700 watts (though it's terrible for the PSU).  Proper functioning S9 shouldn't draw more than 1400 watts at the wall.

I use a combo
1x 1300W  -> Board 1 + 2
 and
1x 1000W -> Board 3 + Controller

Running on 220V.

Thank you for this input. Im eyeing on the 1600w now.
