Mikey, it is not recommendable in any way to do it like that. One of your miners start burning and you need to go to the distribution panel and find the right MCB to disconnect it? Hell no.

Thats against the code in many places, Finland at least. And a serious safety hazard.

You need a safety switch if you connect the power cord directly without an outlet: https://www.katko.com/products/enclosed-isolators/

It should not be too hard to come up with a proper sales thread, including some pictures of the hardware.

E.g. see my old L3+ sales thread https://bitcointalk.org/index.php?topic=3727045

@Epoch
If they all died, could there have been a voltage drop, even way under 208 VAC? And thus, a high current in the input circuit could have killed the psus.

Now there would be a lot of space for AvalonMiner 11 series...! With competetive power efficiency vs. S19 and M30S++.

Yep, it sure is great to see some up movement for a change.

Now at 9.6k USD.

It takes in 12 VDC input voltage, from your server psu. Or in this particular case, from your APW3++ psu. If you don't want to modify cables, then you need to find a pico psu with a suitable connector or find a 6-pin female - female adapter.

I've done a GPU rig powered with a HP DPS 1200 FB-A server psu and a pico psu. It was a great setup. You can find a pico psu for better price in Aliexpress, for example.

Edit: This was the one that I bought from Aliexpress https://m.aliexpress.com/item/32828439849.html?spm=a2g0n.orderlist-amp.item.32828439849&aff_trace_key=&aff_platform=msite&m_page_id=1141amp-jekuphr4TI0-fX27zpw3aQ1595452733747&browser_id=92c5052f659640e6b7d2cfbd9fab77d4&is_c=Y

But then again, depending on your costs that time, it would've maybe just been better to buy coins directly.

I have not opened a APW3++. Does it have an ordinary type fan connector with two pins?

If yes, then Molex KK series (2.54mm pitch) would be an answer for you.

Yeah, I agree that it might not be wise to repair a S9,
but I wanted to help OP with my reply.

Wow, thats getting messy and illegal.

Phil, one fix though: I see it mentioning 17000 T17 units, not S19. I guess it is not so crazy cheap price for a T17.

It is the same for me, I've also got 82% back.

Ouch, it seems that the battle between Micree Zhan and Jihan Wu is getting really ugly and the customers pay the price in this particular case.  

Well, at least it is easy for MicroBT and Canaan and others to improve their sales..

Guys guys, read the manual: https://service.bitmain.com/support/download?product=Antminer%20S19

@favebook
But I do agree with you

Wow nice, and with only about 50Th/s hash rate!
Congratz!

Nice, I love stories with a happy ending! 

The hash board #0 seems to be dead. The A741 consists of four hash boards (two per a power management unit board).
