this is a 'known' feature of some electrical items... including modules... it's called 'inrush'
if it's only when plugged into certain places, I'd move it - possibly some busboards have limits...

Its a phenomena where a capacitor with very low ESR is demanding very high current (becaus of the super low resistance) during startup and therefore the PSU is driven into saturation. That will probably cause trouble initializing digital modules... So yes, moving it would be a good idea... especially considering the lifespan of your PSU
