It's at the 75W mark.
NVidia's own specs don't have the power connector:

From https://www.nvidia.com/en-us/geforce/graphics-cards/gtx-1650/


With that being said, YES it's at the limit of the PCIe spec, but it's one of the best MK/s card at the moment.
Also, and this might be a local thing but, where I live (Long Island, NY) there are a lot of local PC shops that have these 2nd/3rd/4th gen i3 / i5 machines (4GB Ram / old small slow drive) for well under $100 many at the $49.99 price point.

So if you want a machine to run VanitySearch, that will do 500MK/s and not spend a lot you can get this done for ~$250. If you are worried about killing the PCIe slot or the fact that the power supply is old and might not stand up to it. You can get a spare PC and still be under $350.

That is why I made a separate post about it instead of just adding it to the list.

As with everything YMMV but still, I think it's a great deal.

*75W if it follows PCI Express specifications

Which is a huge if:





PCIe slots in older/cheaper boards might die under 24/7 use if a card continuously exceeds this limit.

I think PCIe port only provides 75W or so. What this means is the card will run, but only offer limited performance.
Maybe just pick a card with a lower tdp/performance/consumption/Price in that case?

In some cases also the pci-e is enough in theory but power from the PSU directly is preferred to avoid overheating of the MB/PCIe port.

Just added the GTX 1650 to the list of cards:
https://bitcointalksearch.org/topic/m.50823897

You get over 500 MK/s on a $150 card from Amazon. Not to shabby. ( link to the actual card I am using: https://amzn.to/2yevV7i )

What is *VERY* nice is no PCIe plug is required on that card. So you can run it on systems that don't have PCIe coming off the power supply. The one I tested is now in an old Dell core i3 machine that has the crappy stock power supply that had no PCIe.

actually there is a command for you to save the generated address on a text file and you can use the command below

so the example will be like this VanitySearch.exe -o test.txt 3test and the output will be on text file named test.txt

Hi All, you can add a command to save a list of 100 addresses in a text file and open the next file to save.

VanitySearch is not intended for this, but you need the BitCrack program.

Hello,
As it is no, it is not optimized for that. However with few modifications of the code and a powerful hardware it can be done...

Hello. First of all: great work!
TL;DR: Can this software guess what characters are missing in pair:


I really need it for some of my paper wallets...

Thanks!

Here is the way the final private key is reconstructed:

1) (privKey + partialKey) mod n
2) (lambda1 * privKey + partialKey) mod n
3) (lambda2 * privKey + partialKey) mod n
4) (-privKey + partialKey) mod n
5) (-lambda1 * privKey + partialKey) mod n
6) (-lambda2 * privKey + partialKey) mod n

As you don't know the privKey when mining , it is not possible to calculate an offset to add in order to reduce to case 1.
May be I also missed something...

see
gobittest.appspot.com/VanityAll
used add/mul with comp/uncomp = 4 total
(add + uncomp, add + comp, mul + comp, mul + uncomp)
"Solved work" confirms this in the "Solution type"
(most add + uncomp entries because this is vanitygen default)

mul we do not need. I guess this was a trick to get 2x keys for the price of 1M
(like symY/symXBatch/endomorph proposed by arulbero)

we need the splitKey and the addition candidateKey+splitKey not to change

your program gives the result and does not tell which of the 6algos now
when I tried to write the analyzer in python, I failed twice.
At first, I intuitively applied sym/endomorph to the result of the addition of the candidateKey and splitKey, but 5/6 addresses were not recognized.
Well, Of course, I thought, True choice if applied sym/endomorph to the candidateKey before adding with splitKey, but it all happened again.
There is a third option - you apply sym/endomorph to splitKey!
After which the analyzer determined all cases correctly.
I am surprised by this choice, because it makes your calculation incompatible with 5/6 with the pool.
I guess this is due to the late addition of the splitKey to your self-contained code with minimal edits.
In my opinion, you need to apply sym/endomorph to the candidate and not apply to splitKey or the result of addition
imho, after fix u program should also work fine.
(maybe it have some math depend; maybe, I am mistaken and do not take into account some subtlety or dependence)

Hello,
Yes the split key is done using all the 6 ecc algorithms, reduce it to only one is not obvious.
I don't know exactly how Vanitypool is working, does it support only "add" algorithm for final private key reconstruction ?
Vanitypool supports only uncompressed addresses or both ?

VanitySearch is 6x faster than VanityGen, and even 2x faster for compress addr (12x total).
But new 5 ecc algorithms uncompatible with split-key project vanitypool.appspot.com
So we lose 6x, only 2x left.

The developer vanitypool has long lost interest, the design is missing, the site has not been updated for more than 5 years.
The keeper ThePiachu is not able to screw the sorting of html-table on javascript and, at best, keeps the server on.
Therefore, it is naive to hope that 5 new algo will add to the job calculator. Ok?

But Jean_Luc can do something.
You use symm and endomorph to -sp pubkey.
I suppose it was faster and easier to do when you added -sp to the main code so as not to overwrite it.
We can not change the split-key and the math of calculating the final key on vanitypool.
Is it possible to eliminate symm and endomorph overlay on split-key?
I'm not sure, but it seems to me that there is no problem either in calculations or in safety.
With 12x tasks on the pool will again become more profitable than mining.

Well this certainly deserves a bump. I hope I can figure out how to run it now 

Done

Updated.

Jean_Luc could you put a link to my post in the 1st post so people don't have to go through 15 of the 20 pages to find it. (someone sent me a PM about that)

Also, if anyone wants something added w/o posting in this thread or if you do post it and I miss it feel free to drop me a PM.

Thanks,
Dave

Hello,

Many thanks Dave for you work
A friend of me use a GTX 1660 Ti which gives a very good ratio price/performance (especially for integer calculation)

I been slacking in updating my post of card speeds.
https://bitcointalksearch.org/topic/m.50823897
I hope to carve out some time tomorrow or Friday to go though the thread and update it.
Sorry for not keeping it up.

btw is the private key for address 3 and bc1q is able to import to bitcoin core?


i try the command in my vanitysearch but turn out nothing to search, can you share how to do it via pm or share it here?

Thank you. I would be very happy to do this. But I'm not able do more than few edits =D

I did an exception for char "1" in a code

I think it's impossible on regular GPU for next years
