Hi, and thanks for getting in touch. Given the symptoms you describe, this is almost certainly a hardware-level fault on the TS-253A rather than drives, RAM, PSU, or software. Repeated rapid power cycling that happens before the system finishes POST and continues even after replacing the external PSU usually points to one of three things:
1. A failing internal power regulation stage on the motherboard
2. A failing capacitor or VRM component
3. Corruption or instability in the onboard embedded controller
Once a QNAP begins power-cycling mid-boot like this, no amount of resets, reinstalls, or drive changes will stabilise it. The fact that memtest ran briefly and then crashed during the reboot loop is another strong indicator that the problem is occurring at a board or controller level.
The bad blocks on your new HDD are likely the result of repeated sudden power losses. They do not necessarily mean the drive is physically failing, but they will continue to accumulate if the NAS keeps shutting off unexpectedly.
Qnap support will give you the best guidance.
