Control ATX PSU

Long story short, I’m DIY’ing a JBOD enclosure for my TrueNAS setup. I’m planning to have a separate ATX PSU in the enclosure strictly for powering the HDDs. A low tech solution would be to just install a simple button to ground the Mobo pins to kick the PSU on, but I’d rather use a smart relay. The idea being that I can use HA to power on the JBOD before TrueNAS boots up.

I have a spare Shelly Plus 1 sitting around and was thinking I could just use to, but wanted to see if anyone else has done something similar.

An ESPHome device should be able to ondo it too.
Just remember to have a common ground with either methods.
