I want to find the wattage of my power supply but the sticker on the PSU is not telling me anything.

Seems like the PSU is installed in a computer?

Try removing the PSU and look for other labels on it.

If there are no other labels on the PSU then it is probably a "generic" model, which usually means it is probably a low quality unit.

As to the power rating of the unit, a guess is that it MIGHT be a 450 W PSU as suggested by the notation "PN450EOE0130" on the label.
 


Tried to remove it but there's nothing else to it. Just that sticker. Anyway, It's a really old Prebuilt ASUS Vivo Desktop.



Yes. But I'm not really sure what series this rig falls under. I tried to search for "old vivo desktops" and ASUS' site came back with just the new rigs excluding the older rigs.
