You could use 2 of these

these will do 900 watts on 120 volts.

Do a quick google of series vs parallel circuits you were either putting 24v into the miner or the power supplies were trying to compensate and were doing who knows what.
If it's mining OK now then don't worry about it. But I would replace the 750 units with something bigger.

They do make devices that go from 110v to 220v

You still need enough amperage to do it and they do add another layer of resistance / inefficiency to the setup but they can be used.
Since you can run this on a pair of 110v PSU I would do that, but if you get something that is 220 only so long as you have 110 and enough amps it can be done.

I am running it off 2 PSU now, seems to magically be working.
For some reason I thought having another PSU would help it get more power if needed. I am providing it 1500W now ( 750 on each psu). Just worried it will not be enough to reliably run. I think we found the answer. I will provide another log if issues come up
You might want to run it in the low mode, or balanced with a voltage offset of -2. Default settings in balanced mode pull just above 1500w's, High mode comes out to like 1800w or something like that.

Can you upload a log of it working also? The log you posted doesn't have the miner listed / active or maybe that info is missing.
It should look something like this the only difference should be you only have 1 miner and this pi has 2.
This could be it also, I have run half an avalon on one PSU without any noticeable issue but I've never split the load before. It should be one PSU connected to two PMU's, each PMU is connected to two hashboards. You might be able to get away with 2 PSU's but it's really not designed for that.

How do you have it on 3 separate supplies?
Unless I am missing something if you plug 2 power supplies into 1 of the power boards bad things are going to happen.
Each board should only have 1 power supply if you have to split them up.

*I could be wrong but I know on the other Avalons it's one power bus so multiple PS are bad, never took a a851 apart.

*I could be wrong but I know on the other Avalons it's one power bus so multiple PS are bad, never took a a851 apart.
This could be it also, I have run half an avalon on one PSU without any noticeable issue but I've never split the load before. It should be one PSU connected to two PMU's, each PMU is connected to two hashboards. You might be able to get away with 2 PSU's but it's really not designed for that.
I have this power hungry ASIC on 3 separate power supplies

I dont know how helpful this will be. this log is right after it "Crashes" now. meaning it hashes nice at 14 th/s, but then drops connection. this all happens soon after it is started. It then resets, and then just goes into "low power mode" I call it, as it only hashes at 4-5th/s. I will post another log when I can from the "low power moder" when I can.

I'd suggest posting the log (enable debug first), copy paste the log after it drops, into code tags on here. I've never seen an 851 slow down due to network but haven't used wifi/repeaters for mining ever.
You can figure out if it is because of a bad network communication either by setting up a constant ping monitoring for your wifi setup or by simply trying a wired ethernet connection.
Is your ISP stable?
Is your pool stable?

I did, have referenced it before, thank you for creating that.
I am using wireless repeaters and am convinced they drop or degrade signal. I have ruled out power supply for now.
Will need help deciphering the Log file if possible, thank you in advance

For starters:
Have you looked at my Avalon troubleshooting guide?
It applies for the A851 as well.
(the url link is in ny signature space.)

I have this power hungry ASIC on 3 separate power supplies (each power supply is on a different fuse on my residential panel, I am using extension cords). Each is a 120v 750W server power supply. I actually have an original canaan sorcerer but do not have access to 220v at home (dont know how to make it work at home either, wish i could)
1) My problem is that the hash-rate steadily drops from 14.7 (Advertised speed) , slowly over a 24 hour period all the way down to 3 th/s. I will supply the CCMINER code when I can access it.
2) Should an ASIC run at advertised speed or do they ever go half speed when the network is not busy?
