Power rating for the 720 w/ 960GB:
1.4A@3.3V (4,62W).
Power rating for the original Samsung 256GB in a Mid/Late 2012 15"rMBP:
2.39A@3.3V (7.887W).
--> Transcend SSD has an advantage of 3,3W (41,4%) compared to the original one. Speeds are higher and the chips are even from Samsung as well, so really no reason to complain
Edit: Okay - I have to add a few complaints:
Conclusion: Hardware seems fine, but the software has to be improved.

Edit: Okay - I have to add a few complaints:
- The Transcend Toolbox (v1.5 - latest on website) does not work for TRIM enabling. It recognized the drive correctly and gave information, but always claimed that TRIM would already be active on the machine, which System information denied. Luckily there are alternatives like Cindoris Trim enabler or the Chameleon SSD optimizer (Trim enabler did the trick for me).
- I tried to apply a firmware update. Originally my drive came with v20140402 and the newer version is v20140516 (even though I could not find this out from the filename or a possible read me, but only after I restarted into the firmware upgrade tool - please put the firmware rev. somewhere!).
- The update process seems to be easy, but I had massive problems with my USB3 stick. Disk tool would always say it had to verify the dmg before restoration, but by accepting that it would remove the dmg from source and put the USB stick there (leaving destination empty). Then the verification failed. Once I took that hurdle, I could not get the rMBP to boot at all as long as the USB3 stick was plugged in.
- With a USB2 stick eventually all went well - only the startup took ages (30-60 seconds before anything happened on screen after I selected the thumb drive as startup disk)! Normally I would expect a small Linux based firmware upgrade system to start up quickly even from a slow USB2 thumb drive... there is definitely room for improvement (for starters some progress indicator would be nice)!
Conclusion: Hardware seems fine, but the software has to be improved.

It _does_ fit, though not for everyone. I was one of the impatient ones and ordered the "old" 720 for my 15" - and I was luckyHow do we know which model it is on the amazon site? Will the new updated 480GB for the MBPr, be labeled something different from the one that apparently doesn't fit in the 15"?
