Problems with Antminer S5s and EVGA 1600 platinum

Hey Bitcoin Miners,

I have two of the S5 antminers that I was once powering by two 800 watt Corsair bronze power supplies. I've had this setup running for months, with no problem.

Last week, I put these on the same 1600 watt EVGA 1600 platinum (model # 220-P2-1600-X1), each using two of the dual 6 pin connectors off the power supply.

Both of the miners turned on and I was able to get to the admin page where it showed that they had received work units but discarded them immediately. I let them run for an hour and they never heated up, never started hashing. I tried the power cables on different legs of the power supply to see if it made any difference, and it did not. The network connection was fine as it continued to get work units, but nothing ever processed. They just discarded.

I put the same units back on their 800 watt individual power supplies and they went back to work. I pulled the power supply out and put it in a computer with two video cards. It fired right up and hashed fine in GUIMINER. Thinking maybe I just didn't have something plugged in right with the Antminers, I unplugged the power supply from the computer and re-hooked up the 4 power connectors on each miner. Same deal. Fires up, shows admin screen, grabs work, no hashing. I'm baffled.

Has anyone else had this issue with the 1600 watt EVGAs Platinums?

if they are not generating heat the only possibility, is that they are not taking any current, so or the cables are faulty or the psu is not working properly

i think is the psu, you can try to return it

I ran s5's sp20's and avalon 4.1's with that psu.
I used 120 volt power and 240 volt power with that psu.
that psu has 9 pcie cables

use 4 cables to each s-5 set freq at 350

do not use 2 dual cables to each s-5

a dual cable pulling over 300 watts can trigger over current.

if you want me to pull out the one I have to show hookup I can

Amph - I have two of these 1600s, and they both do it.

philipma1957 - I think you're onto something. I was using the double connector. Can you post a photo of how yours is set up?

sure give me a few minutes.

I don't have a miner in house but these photos should be good enough.

8 of 9 pcie jacks are filled note I had some red cables from the evga 1300 to help you see how I split the 8 cables into groups of 4

note tie offs for this I used all dual jack cables the single jack cables are fine

see how they are kept apart note I plug in the jack that holds both wires not the end jack

so 4 dual cables not 2 dual cable per s5

then only 160-180 watts per cable figure 720 watts max per s-5 more likely less 680

these 4 cables do 1 s-5

these 4 cables do the other s-5

Thank you for the detailed photos! I'll set mine up the same way and see if this works. Cheesy

It should be good if it works let us know if it does not work get back to us anyway maybe we can figure out if there is some other issue.

A swing and a miss with this. I took the miners off their own power supplies and put them on the 1600, putting on leg per unit like suggested. They seemed to power up just fine (like they did before), the mining light blinked and then nothing. Once again, they get local work but don't process anything. I have included photos of the wiring setup for your reference. Any ideas?

I had two sets of cables and two power supplies of the same type, both exhibiting this behavior. I just returned the other power supply as defective, as I thought it was, yet it powered my computer and my Antminer S2 just fine. I really am out of ideas if you guys can't think of anything else to do. Sad

First I would look at this and check connections - https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB

With it being two of them chances that is not the issue but it's worth at least checking.

After I would look at network as possibly as power looks good. Can you upload a picture of network config?

Sure thing. Here's the config I'm using. Note that when I plug this back into the other other power supply, it goes back to hashing without issue.

Networking looks fine as far as settings. That is odd on it not working that that PSU. That is a quality PSU.

What happens if you try other S5 with this PSU? Do both S5's not work with it?

I've tried them one at a time and together, same results.

I tried a third S5 that I use on a 1000 watt P2 Platinum and it does the same thing.

I put 3 of my S3s on this same 1600 watt power supply and they seem to work without issue.

Sounds like PSU is having some problems. Might be worth getting a cheap PSU tester to see what it comes up with them.

It is a tool that is nice to have, although you wont use it often.

Good point. I just bought this one:

When I get it, I'll run each of these leads through the tester to see what's going on.

Sounds good let up know how it goes!

One thing some do with testers is normally they can be plugged into PSU and be used instead of paperclip, etc. Although I believe that nice PSU of yours comes with a resistor to keep them on already.

Try to put some load on +5V rail, old cdrom or hdd maybe.
