PCIe actually includes stand-by power, so this card using usb-c PD and PoE instead would suggest idle power consumption is significant. > It uses about 2-3 Watts at idle, and 4-6 watts when you're remoted in controlling the screen. I think ATX only requires around 5 W minimum for 5 Vsb so yeah… It’s kinda hard to measure the power use of Ilom, something like an AST2500, for a number of reasons. They do get slightly warm, so the chip itself probably burns around 1 W. But system power use when on is of course also increased due to the various links (PCIe, NIC links etc.). Plus around .5-1 W for the always-on Ethernet link - EEE and a quiet management network would help here.

In my testing for the video, the card uses 2-3W at idle, and 4-6W when streaming video to a remote browser session. I haven't looked at the idle power spec lately, but I believe the biggest problem would be when the computer is fully shut down, I don't think you can get enough power to run a card like this?

  PCIe provides standby power on 3.3v only. I can't find a specific number for "standby" but even not in standby it seems to be 1100mA @ 3.3v =~ 3.63W - so may be enough. You'd need a step-up to 5V for the CM4 though. Seems like it may be borderline enough for the video part not being active but maybe similar to USB it might be "not quite enough".
