i bought the x1205 a few months ago, has been working fine until last week, when i started having shutdowns. i use it with geekworm dual nvme hat. i disconnected the board and sprayed contact cleaner, after which it was working ok for a day, then suddenly one of my nvme's dropped off. i previously had a similar issue with x1200 which is the reason why i upgraded

Hello! We’ve received your question. To pinpoint the issue, our first step is basic troubleshooting:

① What are the specifications of your power supply?

② Are there any other devices connected to this UPS?

We initially suspect the shutdown of only one NVME drive is due to insufficient power supply. We recommend trying a DC-powered power supply rated at 12V/3A or higher.

Based on the current information, we can only make a basic assessment—we’ll need your additional feedback to further identify the root cause (Contact us at support@geekworm.com if needed).
