Protection Features
Check out our PSUs 101 article to learn more about PSU protection features. Our protection features evaluation methodology is described in detailĀ here.

There is no OCP on the +12V rail, since over-power protection shuts the PSU down if needed. But with no load on the other rails, Seasonic's SSR-1000PD Ultra can deliver close to close to 114A on the +12V rail before it shuts down.
Over-current protection at 5V and 3.3V is normal. However, at 5VSB, it's higher than it should be; ripple gets out of control with more than 4A on this rail.
Other safety features are present and operate normally, protecting this PSU well.
