Gecko uses 100V MOSFets on 80V rated drives so i have seen plenty of them go up in smoke, but i never managed to kill one of them as they do mention on their web site and provide the schematics for wiring a power resistor and a relay to prevent from killing the drives. I have yet to see some one else use that. I know i did.

I agree, the first time the machine stops abruptly, it will kill the drive.I would not use 48V on a 50V drive. The back EMF could kill them.
40v would be safer. Just my opinion

All my 50V drivers run at 48V without fail (yet)...
I think having multiple drives from the one power supply (mine are switched-mode) helps.

I have KL5056 drives and they are ranged input voltage from 20V to 50V. I also run mine on one Meanwell 48V switching PS, have had zero issues.

If a drive is specified to take a max supply of 50V then it should be able to run motors at 50V. I have about ten 50V drives running at 48V. In the 15 years or so I have not had a single one fail.
Mind you those are high quality Trinamics drives not some cheap knock off from ebay.

It might be enough to kill a Gecko but I have had no issues with the longs motors at 48 volts as I used them for a few years on my spaceship plasma.

The G251x is limited to 50 volts. So get a 10 amp 48 volt Meanwell Switch mode power supply.
I would not use 48V on a 50V drive. The back EMF could kill them.
40v would be safer. Just my opinion

No issues with my 5+ year old Gecko G540

Yes and Hohmann Designs, the Aussie Gecko dealer recommends 48 volt Meanwells too!

Would either of these work? The second model is 36volts. There are so many types of power supplies out there.

Both of them should work fine.

I've been using a Meanwell 350-48 with 3x570 oz/in steppers with KL-6050 drivers for years and the setup hasn't missed a beat.
From most of the data sheets I've seen the DIN Rail mount PSU are recommend that they are mount vertically. So depending on your space this maybe one thing you want to take into consideration.
