My SFF rig has started exhibiting a problem. I’m not quite sure where to start. Admittedly, I haven’t done much troubleshooting yet. A quick visual inspection did not reveal anything obvious.
When I press the power button, the power LED flashes for a fraction of a second. Any subsequent press results in no activity, although the GPU ‘standby’ power LED does remain illuminated, which is normal. The solution thus far has been to unplug from AC for 30 seconds or so, plug back in, then the system appears to function fine. No other ill signs, even under heavier load. I thought it might have been a glitch but the behavior is consistent.
The PC is connected to a (less than year old) UPS. There have been several power disturbances/outages this summer. Even with the UPS, could the PC’s PSU have been damaged? Maybe coincidentally failing PSU capacitors?
I think the PSU is this model:

The PC was originally an Origin PC build. However, I’ve upgraded/swapped the platform and GPU since.
Beyond the inconvenience, I’m sincerely concerned this could be a deeper problem. And… Well… for obvious (current economic) reasons I don’t want the possibility of (other) components to be taken down. Thus, foremost, despite it seemingly working fine on second boot, should I not run it for lengthy periods without narrowing down the cause?
I’ll try some further troubleshooting though… even reseating RAM feels scary as it’s probably more valuable per ounce than gold right now. 😆 🙁
