Check out our PSUs 101 article to learn more about PSU protection features. Our protection features evaluation methodology is described in detail here.
| Protection Features | |
|---|---|
| OCP | 12V: 86A (138.71%) 5V: 28A (140%) 3.3V: 27.6A (138%) 5VSB: 6.1A (203.3%) |

| OTP | ✓ (120-130°C @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor & bypass relay |
Seasonic's over-power protection (OPP) is set high. Normally it should be configured to trip at around 120%. Over-current protection (OCP) at 5V and 3.3V is set at normal levels, whereas it's quite high at 5VSB.
Finally, we observe short circuit protection on every rail, the power-good signal is accurate, and surge/inrush current protection are accounted for.
