Failed Empiretech PSU?

So I bought an NVR16CH-AI-S2 from Andy in May 2026. I know the PSU and NVR worked initially, as I powered it up on the bench to perform some initial configuration.
It then sat around for a while as I slowly built out the infrastructure in a new building, until this month I finally had enough in place (power etc), that I thought I would do a quick power-on of the NVR, making sure the lights and HDD powered up. (I didn't even have a monitor with me).

Plugged in, switch on, nothing. So I measure DC out of the PSU; 5.x volts... It's meant to be 12v I believe.

Now I know switch-mode-power-supplies can show erroneous outputs when not loaded, but 5v plus a dead NVR makes me think the power supply has had it.

Has anyone else had this? Has anyone measured the output of a known-good Empiretech PSU?

I have no idea why it would have failed, it was not always dead, because, as mentioned, it worked initially on the bench, but it has not even been powered on since then, so I don't know why it would have failed!!

reach out to Andy he will take care of you
 
Just checked for you, 12.2 VDC and yes I have had a PSU fail on these.
Make sure the brick didn't come loose from the plug, very common.

I'm sure Andy would replace it for you but you can grab one usually overnight from Amazon for 13 bucks. 12VDC 4A.
