That said, no miner made gives us a readout of actual power used. They do give us logs of voltage applied to the chips but do not have current sensing. Without a way to sense (and know) the current being pulled, voltage is literally only 1/2 of the equation used to calculate power.

For a start -- the opening post of this thread should point you in the right directions....

Re-directing or outright blocking the devfee address is not the hard part: the fact that the miner is also looking for those (sucessfull) connections and will stop mining when it no longer gets the correct responses when it tries to switch to the dev pool. In short, it is a software based license key dongle.

The clean open source code is freely available from 2 github sites ran by the 2 original major developers of it, -ck and Kano with Kano's being the most up to date as -ck locked his site long ago. Download it and do your own search for it.
If you are any sort of decent programmer that will be no problem, if you are still learning then consider it as a learning exercise.

Ever hear of PM?
You posted in a public area so one should expect replies from the public... 

....
You CANNOT mine BTC using anything other than an ASIC-based miner.
Period.
Perhaps try reading some of the pinned messages here - mainly point 3 - to avoid posting such ludicrous questions...

Then you will not be buying any BTC miners from anyone. It ain't cgminer (or the various ripped off versions of it) that is 'broken' and needs 'fixing'. It is Core that broke solo mining and as Kano already pointed out, it's far from ideal to use a version of bitcoin prior to 0.21, since when taproot activates next month, you must be running 0.21 or later.

Considering that unless you have excellent connections to the other mining nodes on the internet it is a HORRIBLE idea to mine to your own node with a high risk of finding a block and then you losing every orphan race to better connected sites, there is no pressing need for cgminer to be patched to allow doing it.

No, odds are they the ubiquitous PCIe connectors. There is no such thing as an 'ATX' connector.

That said, odds are ones from ebay or other grey-market sites are crap. As long as you do not unplug/plug them more that a couple time they should be fine but will wear out after just a few mating cycles. It is far better to get power components from reputable distributors such as DigiKey, Allied, Mouser, etc. where you can choose the type and quality you want.

Good to know
Merit given for keeping us in the loop!

It would NOT change what PD can deliver. Same as with the USB charging specs the power delivery voltage is a wired negotiation between the master and slave(s) where there is a set of resistances presented by the slave device across the power wires when you plug it in. Something like either 10k, 4k or 2k as I recall. The master sees that and sets voltage output - up to 26vdc -  and current limits accordingly. The regulators in the slaves of course need to be able to handle that so if no initial handshake resistance is seen by the master the port limits output to the standard 5vdc @ 1A.

That out of the way, a USB-C PD port can both deliver power and handle data -- it's just that data has to come from/go to a different master (for data) device port. In the case of say a laptop using a powered USB-C hub with a PD port that is sized to power the laptop (up to 100w) the hub is the master for PD while the port on the laptop is the master for all data xfrs. The one cable between the laptop and powered hub handles both power to the laptop as well as data to/from it and the hub then splits off or passes through the (data only) to whatever is plugged into its data or display ports.

Their thread is here Since it is not just a miner monitor and is also heavily designed for altcoin algo/type switching, discussions about it are in the Altcoin area of the Forum and not here which is a Bitcoin-only area.
That said, it's very very good for monitoring and controlling miners. I've ran my farm with it for years.

Good summary of the situation here in the US though it should be said that a good part of the 'new found' power in Texas and other states is coming from natural gas powered plants that were normally used as peak/reserve plants. In the past 2-3 years it has finally occurred to the operators that they can put that reserve capacity to work mining crypto whenever the plant is not being called on to do what it was designed for. Even with gas turbines it takes a fair bit of time to ramp up from the normally low baseline output to whatever max capacity the plant can produce. Technically the power plants are 'losing' money when the plants are idling.

Having the ability to keep the plants running much closer to full capacity while reaping large profits from mining farms is a win-win for all involved. The plants run at much higher efficiencies and because there is usually a fairly short run between the power plants and the farms, very low infra cost to deliver the power. The one catch is to have the needed agreements in place so when needed, mining loads can be shed so the plant can fulfill its design purpose: provide power to the grid when required. Once grid loads subside the miners restart. The various Texas power utilities did that last year with the farms located there and in fact paid the farms a fair % of lost revenues during the power outages for them to stay off line until the Public Needs were fully covered.

That peak loads plant located in upstate NY that made headlines for 'heating up the lake' last year is another example though in their case the mine is actually located on the plants property and is directly ran by the power company so there is no paying someone else to throttle back when needed. For them it's now part of normal operations balancing capacity to grid load. Their now being able to redirect 10's to 100's of MW within minutes by switching miners off and then later back on vs well over an hour slowly ramping up the power sources and generators then the same to bring them back down to idle status is a Godsend.

As for coal-fired plants still being viable despite the carbon emissions... Thank 'Inconvenient Truth' Al Gore for that. He and his family advisors are the ones who came up with the idea of carbon credits: the buying and selling of industrial carbon footprints and offsets to them. That and that alone is why there is a lot less hue and cry about coal plants in the US vs other countries. Coal fired plants here per legal definitions and standards of accounting can have a relatively 'low' total footprint because they are paying for others to Go Green. The carbon footprint reductions other companies are 'saving' is subtracted from what the high emission industries produce when said industries purchase carbon credits. Yes there is a gov regulated market for that in the US. Normally high carbon footprint industries still have to reduce actual emissions as much as is economically feasible but being able to buy their way out certainly helps the accounting...

To bring us back on track with the main topic the end result of all the 'new found' cheap power in the US means that should be an interesting year for Diff as more and more farms start up here with new equipment coming online.

Wrong area of the Forum to discuss that.  Use the General or Altcoin areas. This area is for Bitcoin Mining using hardware only.

Back to the topic, the 1st block I was paid for at Kano pool was on 2014-Oct-26 21:15 with a Diff of 35,985,640,265.08 . At the time I was running 574.09GHs.
To-date I've found 10 for the pool

Oh? There are 2 folks that were running Solo who each hit a block in the past 3 days that will strongly disagree with your statement. Granted it is highly unlikely there will be a repeat of that anytime soon but nonetheless it is all just a matter of Luck. Also do not forget that regardless how massive a pool is, it is still just 1 miner in the pool that finds a block. It could be a faily low 2-3 THs or it could be a TOL 110THs miner but it still just 1 piece of hardware.

There is no 'I think' about this. It IS a SCAM! Period.

Read the pinned msg at the top of this area, mainly point-3 The main point is that CPU/GPU's are generalized hardware designed to do many different things. Being programmable means that there are many different operations going on moving data between various registers and buffer locations when processing data and all of which consume many clock cycles for each hash operation.

as their name clearly states Application Specific Integrated Circuits are hard-wired to do 1 thing and 1 thing only. In our case they crunch sha256. A single ASIC chip contains several thousand cores (the Bitfury chips in the Apollo each have 4096 cores) with each one working on different nonce value and spit out results every clock cycle in pipelined operations. Add to that the fact that most modern miners each contain several hundred of said ASIC's and there is just no possible comparison in computational density and power efficiency.

re folks paying fees and specifically, ccard fees - at least in the US, the one place where it is obvious how much of a fee you pay for the convenience of using a credit/debit card vs paying cash is buying gas. Most gas stations charge (and are required to advertise it on their signs) around 10-cents more per gallon vs paying cash. In my area that is currently about a 3.25% fee for the 'convenience' of using a card. A lot of small stores and restaurants will have a minimum you owe to use a card and often give a few % discount when paying cash.

Read the 'friendly' pinned msgs at the top of this area.... Mainly point-3Maybe it *could* work with some crapcoins but they have their own area for talking about them.

These days virtually all miner PSU's have active PFC and will not need external caps to keep the utility company happy.
Now if you are running a lot of motors or very old switchmode power supplies that do not have active PFC then you may need to look at that. As for the big florescent lights -- maybe, though I'd think that if PFC was needed for them it would have been done when the place was built.

Bought what test fixture, and from who. There are a few different ones out there...
