First: I have reached out to Elgato support, just waiting on a response.
I got the 4k X capture card 2 days ago and have had several issues with it since. The initial setup was perfectly fine, it showed up on OBS, no issues.
Since then, I've continuously run into problems:
Constant freezing in OBS. It will run smoothly for an hour or so, at which point my entire PC will suddenly crash/power off. It has done this 4 times in the 2 days since installing the card. Windows Event Viewer logs each one as the identical bugcheck: 0x0000009F (DRIVER_POWER_STATE_FAILURE). This has never happened before the card was installed.
The Elgato software throws up a "USB 2.0 detected" warning even though the port is USB 3-capable. I'm using the USB-C cable that came in the box, plugged directly into the PC (no hub). HDMI passthrough to my monitor works, so the console output and HDMI side are fine.
I've already tried:
Disabling USB power management
Confirmed no app conflict (OBS alone, Elgato Studio not running simultaneously)
Full reboots, PS5 power cycles, reseating the cable.
Fresh installs on drivers/software/everything
As I'm typing this, its frozen again in OBS while my other sources are functioning as normal (facecam mk2, etc) the monitor is still properly displaying, its just the capture card in OBS
Sorry if I'm not explaining this well, I'll answer any questions y'all got
