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 | 12V1: 35.6A (142.4%) 12V2: 36.0A (144%) 12V3: 38.2A (127.3%) 5V: 28.0A (140%) 3.3V: 29.75A (148.75%) 5VSB: 4.6A (184%) |
| OPP | 721.51W (131.18%) |
| OTP | Yes (>130°C @ +12V heat sink) |
| SCP | 12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes |
| PWR_OK | Operates properly |
| NLO | Yes |
| SIP | Surge: MOV Inrush: NTC Thermistor & Bypass Relay |
Because we didn't see excess ripple or lousy load regulation, it's fairly safe to conclude that OCP is configured properly on all rails. The OPP triggering point looks to be a little higher than usual, though the PSU doesn't have a problem delivering over 720W of power subjected to normal operating temperatures.
This platform features over-temperature protection, which is set quite high since the unit is rated at 50°C for continuous full load delivery. Moreover, SCP is present on all rails and the power-good signal provides accurate information to the system. Finally there is a MOV (Metal Oxide Varistor) in the transient filtering stage for protection against spikes, while the inrush current protection consists of an NTC thermistor and a bypass relay.
