Apple uses a custom SSD design which is different than the M.2 standard. So the bottomline here is the Samsung 970 EVO PCIe/NVMe SSD won’t work in your system. Here’s a good reference on the Apple SSD’s The Ultimate Guide to Apple’s Proprietary SSDs
As it turns out Samsung was contracted to make the custom Apple SSD’s and here is the drive you’ll want 768GB SSD It’s the largest blade mSATA SSD your system will support. Here’s the guide you’ll need to follow to install it 27英寸iMac（EMC 2546）刀锋SSD的更换
Sorry your system can’t support the newer PCIe/NVMe drives.
If you really need this much storage your other option is to replace the 3.5” HDD with a larger 2.5” SSD drive. The prices for SATA SSD’s has dropped quite a lot and you can pickup a 2 TB or even a 4 TB without needing to rob a bank.
The last option is to forgo the internal drive and just go with an external Thunderbolt RAID drive.
If you really want more performance than what SATA offers internally you’ll need to upgrade to a newer iMac which supports PCIe/NVMe blade drives. Take the time to review the guide I linked above for more details.

Hi Dan, thx for your answer. There is a solution with an adaptor maybe ?
Best.
Do you play Russian roulette? Not a very safe game is it. Sadly, that's the game you're playing here.
Using funky adapters is not my thing and I've seen to many messed up SSD's from them.
The issue is CRC's these are read/write errors that cause the system to cycle constantly trying to write the given data block to the SSD. Over time the block becomes bad from wear. The bottom line the SSD wears out prematurely!
In a MacBook Pro it's easy to get to, the amount of work on an iMac to get to it is quite extensive. Stick with the real SSD .

No it will not be compatible
A1419 late 2012 its compatible with M.2 NGFF SATA SSD like example “ KingSpec 1TB 2242 M.2 SSD NGFF “ only you get around 480 Mb\s due to the motherboard capabilities
A1419 late 2013 its compatible with M.2 Nvme + Adapter + your drive samsung 970 evo or adata 8200 pro. But only will work to around 900 Mb\s due to the motherboard capabilities.
Newer iMacs late 2015 can handle to 1500 Mb\s
2017 and 2019 you can get of course faster speed with your same drive.

A1419 iMac 27" late 2015 with adata xpg 8200 pro 500gb + sintech adapter = read speed is 2.886 mb/s and writing speed 1.974 mb/s with black magic disk speed test
With bootcamp windows 10 pro and crystal disk speed test the same setup running reading speed up to 3.300 mb/s and writing 2970 Mb/s
[image|1916500] iMac A1419 27” i5 3.2 8gb graphics 1 GB MacOs Mojave 10.14.6 + Samsung 860 evo 500Gb internal sata connection. ( Original HDD replaced) + sintech adapter + NO temperature sensor added. NO fan faster speed/spinning problem detected. No sleep problem with Mojave 10.14.6 clean installation and boot rom updated 140000000 version
Read speed 477 Mb/s Writing speed 517 Mb/s blackmagic disk speec test
But one can use https://www.akitio.com/expansion/thunder... for connecting external NVME ssd to iMac and use clover bootloader on USB flash or internal HDD/SSD for booting from NVME SSD!
