Old revisions (2017-2018) will shut off on some GPUs (970, 1080 ti, vega 64, Vega VII, 2080 ti). it'll will trigger the overcurrent protection, and will shut down immediately. This is likely due to the high transients the GPUs are known to put out
New revisions (2018-2019) have a bigger headroom, but aren't built for it and start to ripple at the loads where the PSU would shut down at with the older revision.
e per far esempio di eccezioni, tra gli 'old', l'Enigma G2 invece ha la protezione tarata diversamente e pertanto NON scatta con quelle gpu [vabbè, la vega sappiam tutti che caso umano sia ?]
