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 | 12V1: 32.1A (128.4%), 11.8V 12V2: 33.5A (134%), 11.7V12V3/4: 52.2A (>130.5%) 11.68V 5V: 33.6A (134.4%), 5.07V 3.3V: 33.7A (134.8%), 3.299V 5VSB: 7.1A (236.7%), 4.772V |
| OPP | 1459.89W (121.7%) |
| OTP | ✓ (165°C @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor & bypass relay |
The OCP triggering points on the +12V rails are higher than Enermax's specs, as expected, with the 12V3 and 12V4 rails being over 50A. The minor rails are set at a normal level, according to our experience so far, while the 5VSB rail's OCP point is sky high at 7.1A! Nonetheless, it keeps its load regulation in spec, and ripple is also controlled well.
There is over-power protection, which works well. Over-temperature protection is also present.
As we've mentioned, the power-good signal is accurate. There is a short circuit with earth on all rails. And the NTC thermistor, responsible for inrush current protection, is supported by a bypass relay.
