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: 71.8 (143.6%), 12.147V 5V: 28.2A (141%), 5.038V 3.3V: 27.2A (136%), 3.336V 5VSB: 4.2A (168%), 4.793V, >65mV ripple |
| OPP | 876.88W (146.1%) |
| 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 |
This fanless PSU delivers almost 877W of power before its over-power protection (OPP) kicks in. That's impressive, to say the least. Over-current protection (OCP) on the minor rails is set normally, given our expectations. Meanwhile, it should probably be set a little lower on the 5VSB rail since ripple gets out of control with 4.2A of current.
The over-temperature protection feature is configured properly, given the lack of a cooling fan. Short-circuit protection is available on every rail, the power-good signal is accurate, and the PSU is protected from voltage spikes and large inrush currents as well.
