The description highlights the setup and troubleshooting process. It mentions issues with power delivery, USB connectivity, and initial observations during inspection. The focus is on diagnosing the cause of problems and confirming functionality when properly connected.
It seems only the USB-C port is malfunctioning. Are you certain the connector is inserted into the right pins? Could you share some photos? It appears the connection isn’t delivering power or showing any signs, though it’s easy to misplace things sometimes.
Corsair RM650 is a 650 Watt 80 Plus Gold ATX fully modular power supply. It has the correct USB-C front port for your motherboard. I’m sure it’s the right choice—just give me a few minutes to update this post with some images. Edited October 25, 2020 by JacketyJack4 pics
Which port you need depends on whether you're using a motherboard or a cable.
You'd need to experiment with another mobile or enclosure to pinpoint the issue. It seems likely it's the case. Just to confirm, are you connecting the cable correctly? I understand it has a keyed mechanism, but sometimes they can still be inserted incorrectly.
They appear to be in good physical condition. Are you certain the connection is correct? It seems to fit only one orientation. If that's the case, could you remove the cable or panel and test it in another system? Since it functions properly without being plugged in, it might be the cable or the front panel connector. You could leave it unplugged for testing, or try connecting it to another motherboard to help identify the issue. Assuming the wiring was correct initially.
