This is exactly the power supply:
SSR-1200PD
Says
Protection OPP, OVP, UVP, OCP, OTP, SCP
We tested voltages with meters and all where in range, also powered another computer with it and all ok. No big load however. I have USB 40MHz Oscilloscope around. Will have to figure out how to safely add some load to it.
