Protection Features
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: 82.8A (116.9%), 12.054V 5V: 33.2A (132.8%), 5.033 3.3V: 33.5A (134%), 3.312V 5VSB: 7.3A (243.3%), 4.88V |
| OPP | 1016.96W (119.6%) |
| OTP | ✓ (170°C ambient @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor |
The OCP triggering point at +12V is set properly, while the minor rails are a little higher, at around 135%. It seems as though the 5VSB rail is super strong; at 7.3A, the voltage levels are still within its limits. Over-power protection is configured well, at 120% of the PSU's maximum-rated capacity.
Over-temperature protection is set a little higher than usual in order to cope with the PSU's extended passive mode (when the minor rails aren't pushed hard, at least). The power-good signal is accurate, and short circuit protection is available on all rails.
The lack of a bypass relay for the NTC thermistor is strange for such a large platform. There's definitely room for one.
