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: - 5V: 26.7A (133.5%) 3.3V: 27.3A (136.5%) 5VSB: 5.4A (180%) |
OPP | 1168.46W (137.47%) |
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 |
Over-current protection on the minor rails is set to normal levels, while it's quite high on the 5VSB rail. Not to worry, though: the PSU's corresponding circuit handles the increased load without a problem.
The OPP's triggering level is also quite high, at almost 137.5%. We think it should be set lower, to roughly 130% of the PSU's maximum-rated capacity.
Seasonic does enable over-temperature protection, a feature that every power supply should have. It'll save the PSU in case of a fan failure, for instance.
Lastly, the power-good signal is accurate, since it drops before the rails go out of spec.
