Hi Pavel, I forgot about this. Was/Am pretty busy recent weeks.

Sent email to Seasonic.

For the OPP testing, you gotta consider max de-rating.

At normal temps a decent PSU can easily go higher and for pushing 150W of heat, sure, it is 80 PLUS BRONZE only.

For your UVP measurements, I will check that when I have time again. (Likely after Computex)
