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.
| Protection Features | |
|---|---|
| OCP | 12V: 113.917A (137.25%), 12.257V 5V: 33.4A (133.6%), 5.03V 3.3V: 31A (124%), 3.31V 5VSB: 4.1A (136.67%), 4.83V, 74.3mV Ripple |
| OPP | 1396.29W (139.63%) |
| OTP | ✓ (160°C @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor & bypass relay |
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.
