Protection Features, Evaluated
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: ✗ 5V: 28.2A (188%) 3.3V: 26.15A (174.3%) 5VSB: >4.1A (>164%) |
| OPP | >750W (>150%) |
| OTP | ✗ |
| 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 minor rails are quite high, while OPP is set sky-high. The PSU might survive a 750W load under normal ambient temperatures, but it probably won't be so lucky under high operating temperatures for a prolonged period. OPP should typically be less than 130% of the PSU's max-rated capacity.
We heated up the secondary side, and at up to 130°C there was no sign of OTP. In other words, the specs are correct and this protection feature isn't supported. That's a great shame in light of Enermax's premium price. At least the other protections are properly implemented and the power-good signal is accurate.
