Pandaboard 5v power supply

A few days ago i noticed that my panda-board died. This is one of the 2 ARM systems on fate.ffmpeg.org.
Resetting or unplugging and re-plugging did not help. Replacing the power supply with a random 5v supply made it come back to life.
The failed power supply is a HNP-24-050 “HN Power Germany”. This is now probably the 3rd or 4th failed power supply for my panda board. The one its running on currently is a random one from ali-express. I must say iam really disappointed by the trash that some german electronic shops sell. All the failed power supplies where bought from germany, not china. The failed supply still produces 5v but when subjected to the slightest load its output collapses to 0, even 200mA is too much.
Ive read on the net that some digikey supply is recommended but both part numbers i found are marked obsolete.
Anyone has any recommendations ? I am not too positive that the 2€ +free shipping supply its running on currently will last very long.
I know i can just run it off a brand name ATX supply or a bench supply but that is a bit inconvenient.
Also if anyone wants to add more ARM hardware to fate.ffmpeg.org, so we have a bit more redundancy, thats certainly welcome
