Hey disco67 🙂

ERP is something you run on your PSU. If your PSU is ErP capable then you can enable that functionality/behaviour in BIOS.

You don't mention your make model but if BIOS wont enable it maybe the PSU is not ErP certified?

The PSU is a Corsair AX1200i. Can other BIOS setting block this function ?

No. ErP as Arne said is either supported by the PSU or not. Also different PSUs support it in different ways.

It's only a matter of the PSU. The motherboard supports the standard and the toggle switches it on or off. The PSU has to act on the toggle if it supports it or not.

Ja, but in this case the software switch toogle a fraction of second and return immediately to "disable"

This happens because the PSU does not support ErP.

I did a bit of googling and it seems that your PSU does not support ErP anyhow (According to product listing at scan.co.uk which was the only page I could find that listed this in the specs) so I don't think it's working even if you've toggled it on.

Ai Charger would prevent the toggle because you can't charge devices when the PC is off if ErP is enabled and properly supported. I didn't think of this earlier.
