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: ✗ 5V: 37A (148%) 3.3V: 36.1A (144.4%) 5VSB: 4.6A (153.3%) |
OPP | 793.541W (122.1%) |
OTP | ✓ (155°C @ Secondary side) |
SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
PWR_OK | Operates properly |
NLO | ✓ |
SIP | Surge: MOV Inrush: NTC thermistor |
The OCP triggering points on the minor rails are set high, while over-power protection kicks in at around 122% of the PSU's maximum power output; it's configured properly.
We didn't find anything to indicate whether the PR-BP0650-SM has OTP or not, but we tortured it with our heat gun and finally got the PSU to switch off at around 155°C on its secondary side. This is a very high temperature; we'd normally want it 20-30°C lower.
Finally, the power-good signal is accurate, though as we mentioned the hold-up time is very low.
