Trashing 2 SSD's back to back would be unusual, so I think you have another issue. My late father was heavily into electronics and he would always advocate any project should start with a stable power supply that is unstressed. I would check the psu, named brand, age, is it running stressed ie look at the power draw of components. If this is a pre built system, have you added to it, pre builds tend to be specced for just that config. Odd things happen with psu's under stress or aging you can get fluctuations or drop of on one rail and not others. If that is fine then I would suspect motherboard.
