I’ve had the main case for a year or two now, and decided to upgrade to the M.2 SATA SSD case in April. Since then I’ve had troubles with sporadic, but persistent under voltage problems. So far I’ve tried the following:
- Buying and using the Argon 40 15-watt power supply
- Turning off overclock
- Buying and using a powered USB hub for any peripherals.
To no avail. At this point there are three potential problems: something wrong with the Pi or v2 case (doubtful, worked fine for over a year, problems started upon install of the M2 case.), something wrong with the M2 case and board itself, or something wrong with the SATA ssd.
I think it is the result of the SSD pulling more power than the Pi can provide through its USB ports, which discussions about the product on the raspberry pi forums have mentioned as a concern.
Has anyone had any similar difficulties? What SSD do you use in your setup? I am using a 128 gb Transcend MT430S SATA SSD and I can’t actually find any helpful information on how much power it pulls (only voltage- no amperages).
I’m very frustrated with this because there was no indication that this might be a problem anywhere, and now I’ve sunk an additional $50 trying to solve it.
…and now having researched it, it seems like a flawed product even in concept since the Pi can only put out 5v/1.2a (6 watts) over its USB port and some M.2 SSDs can pulling more than that, with little that can be done to determine whether an SSD is “compatible” beforehand.
