Panel inside causing issue with HDMI connection triggering a short circuit.
Panel inside causing issue with HDMI connection triggering a short circuit.
I made a new installation in a Cooler Master NR200P enclosure. Many users have added an internal sensor panel inside the PSU housing. After some troubleshooting, I discovered that touching the HDMI cable to the internal display while connecting it to the GPU causes a short circuit, cutting power. Removing the HDMI connection restores power and normal operation. I've seen similar setups on PCPartPicker and Reddit, so it seems feasible. I'm unsure why this is happening—perhaps the standoffs or cable connections are misaligned. I considered using plastic or rubber standoffs instead of metal ones. Another thought was that I might have ordered a 5-pin USB power cable for the display, missing the 9-pin header, which could affect signal integrity. It's possible this is causing the issue. I've just switched to the correct 9-pin cable now, but it's still worth checking standoff placement and connections. Build Photos Internal Sensor Panel Display
I can attempt it without the screen mounted to check for differences; it's quite challenging to take apart, but that's what I expect from an ITX build. I might also test using the USB cable that came with it and connect it to an external port to see if it helps. Also tried two different slim HDMI cables, both gave the same outcome. I plan to try the 9-pin cable once it arrives and will update once I can test them.
Start with a basic USB cable inside the case to test. If issue changes, remove it and check again. If not, try HDMI.
