      Hi all, I've got a Raspberry Pi 3B that all of a sudden is given me low voltage warnings. The strange thing is that I have not changed anything for a while and it is all of a sudden giving me this power issue. Does a power supply degrade over time, or is something on the fritz in the Pi? Last thing I can remember changing is the fan, but I'm pretty sure it still operated normal after this. I might swap this over again this weekend in case that's the problem.

      I have an official power supply and my overclock settings are as following:
      gpu_mem_256=128
      gpu_mem_512=256
      gpu_mem_1024=256
      overscan_scale=1
      arm_freq=1300
      over_voltage=6
      temp_limit=85
      core_freq=500
      gpu_freq=500
      h264_freq=333
      avoid_pwm_pll=1
      gpu_mem=550
      v3d_freq=500
      sdram_freq=500
      sdram_schmoo=0x02000020
      over_voltage_sdram_p=6
      over_voltage_sdram_i=4
      over_voltage_sdram_c=4
      hdmi_drive=2

        Is it plugged directly to the wall?

        The short answer is yes the ac/dc adapters can go bad and output less voltage over time.

        The long answer is that this generally takes a very long time. If you are plugged into a surge protector or power strip that is much more likely to be the culprit imo.
