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.
|OCP||12V: ✗ 5V: 28.2A (188%) 3.3V: 26.15A (174.3%) 5VSB: >4.1A (>164%)|
|SCP||12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓|
|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.
