ATX like corsair or seasonic or evga are not suppling the big psu's.

all evga 1600 watts are out of stock
https://www.evga.com/products/ProductList.aspx?type=10&family=Power+Supplies&chipset=1600+Watts
as are all 1300 watts
https://www.evga.com/products/ProductList.aspx?type=10&family=Power+Supplies&chipset=1300+Watts
and 1200 watts
https://www.evga.com/products/product.aspx?pn=220-P2-1200-X1

The 1200 / 1300 are available at many retail locations.
The local Microcenter here on Long Island has them.
The 1600 comes in and out of stock very quickly but I have seen them.

Other then that, yeah you are 100% correct.
There are some off brand ones at other retailers, but not something I would trust long term.

they simply refuse to supply replacement parts and all of us that have any of the gear i just mentioned dead in the water due to lack of replacement psu.

cannon all oem bespoke psus took me 150 days to get a psu that was 50th lost for 5 months
bitmain 300th off line dead psus.
microbit 100 th off line dead psus

so 450th offline and 1100th online.

100% agree with you.
If I had some merits I would give you some.

I have a contact which is specialized in refurbished PSUs. He is telling me exactly the same as you every day.

If I look his business, I go to the conclusion that repairing PSUs is a VERY profitable job actually.

Actually it goes beyond the bespoke custom psu's listed above.

the reality is that :

the four companies basically are acting like opec and controlling the supply of gear.

many say there is a chip shortage and that has slowed gear.

since this is the btc only section I will not mention what I did with gpus I purchased since I could not get asic psus

oh I did buy some replacement psus which have all been used.

so why do the companies not sell the psus. simple they all cloud mine and they fix their own gear.

this is their edge since they can not sell gear due to lack of chips.

this will not end until dec-feb maybe later.

I did not know that! That is so shady and wrong, but that keeps them in control of supply like ya said. No wonder they started switching to the integrated ones and made their custom ones...

Ya know, there is nothing special about miner PSU's, we just need information on the output voltage range, max current, and voltage adjustment scheme (analog 0-10v or digital signals) and then talk to Accropian, Delta, or one of the many other makers of custom PSU's to have replacements made. Would not be cheap but certainly doable...

since 2014 mining farms have never set up farms in those locations.
they had already decided to set up in regions of renewable and enjoy special electric price contracts in those regions because of renewables.
thus. non-big-deal

I knew it the moment I saw one of your posts that this is going to be a day I will run into you on every damn topic.
So, if you say that Chinese miners have abandoned those regions since 2014, can you please let us know where Bitmains's main farm is, where did they move when they "reportedly by you" leave Ordos? I guess nowhere since they've left in 2014 to be back in 2017!

Second, if all those miners have left Inner Mongolia and Xinjiang why did this happen:

Or is it possible that you don't trust data from btc.com now?

Under the Chinese government's crackdown on Bitcoin mining farms, the Bitcoin mining hash rate is decreasing.

china announced a crackdown of mining farms in coal power plant regions
since 2014 mining farms have never set up farms in those locations.

Thanks, I used to think that Bitcoin mining factories were shrinking because of the government. So the Chinese bans we hear about now are just a repeat of the old laws they applied.
Hardware upgrade is the main reason for the decrease in the Hash rate. I believe Bitcoin's hash rate and value will continue to set new ATHs. A good time to buy Bitcoin could be now.

most of the hashrate volatility is hardware upgrading and also america not mining because the price is sub $35k so its not profitable to mine IN AMERICA

hense the slushpool lack of US block solves when price was under $35k

Under the Chinese government's crackdown on Bitcoin mining farms, the Bitcoin mining hash rate is decreasing. In the future, the hash rate will recover and increase as miners will upgrade equipment and find a favorable place to continue mining.

Information about a 50% drop in hash rate is incorrect. You can check it out at the following link

You either don't know what 50% means or you don't know that the total bitcoin hashrate for the past 3 months has been about 130 EHS. You also seem to be incapable of looking at the hashrate stats which shows that hashrate for the most part has been pretty much the same with normal ups and downs for the past 9 months. Even if you bothered looking at the recent hashrate in June you can see that it has gone up from about 118 EHS to 140 EHS.
On top of all that China doesn't even have 50% of the hashrate in total all around their vast country. Even if they banned bitcoin mining country wide (which they won't) the hashrate won't drop nearly that much.

to explain more detail

imagine its costing you say out of 17exahash (not accurate split of hashrate. pencil numbers for demo)
4.25exa US at 12c/kw ($1.2mill a day electric)
4.25exa EU at 16c/kw ($1.6mill a day electric)
8.5exa china at 4c/kw ($800k a day electric)

which pool do you switch off first
(i done the math using s9 asics.)

now imagine you switched out s9 for s19pro
and you can have
4.25exa US ($723k electric)
4.25exa EU ($964k electric)
8.5exa china ($241k electric)

you no longer need to earn $3.6m(100btc(16 blocks)) to break even with world wide coverage using S9
instead you only need to $1.8m(56btc(9 blocks)) to break even world wide with s19pro

.. separate scenario. which can explain the lack of america block solvers in scenario pool above

infact. if you just switch off US and EU. you only need to earn 1 block to break even.
yep have 8.5exa in china and only need 1 block to break even.. easy.
or have say 13exa in china and switzerland and only need 2 blocks to break even

so why run american stratums knowing that its costing those miners more than they are earning

remember on average electric prices of america.. its about a break even threshold of about $35k a btc to mine and break even.
if price goes below $35k a btc then its not worth it to mine in america

China is getting serous banning crypto mining farms, will take 10-15 days to go up again

not a china ban
but a upgrade of miners and keeping hashrate down to avoid a difficulty jump

they dont want the difficulty to be 50% higher than this time last year
they are trying to keep it below 20Trillion

..
and at time of writing this. i just checkede a couple pools.
and the funny part is.. the pool 'btc.com' yesterday (17exa) had a equal amount of china/eu/us stratums finding blocks. but today(13exa). EU/US have not submitted any blocks
meaning china was still mining but EU/US has not been mining
