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: - 3.3V: - 5VSB: - |
| OPP | 1279.097W (127.9%) |
| OTP | ✓ (140-150°C @ Secondary Side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC Thermistor & Bypass Relay |
We didn't get any OCP results because our unit died during the OPP test, meaning either that this particular sample had a problem or OPP is set very high. Note that we conduct these tests at normal ambient temperatures, below 30°C.
OTP is set very high, as we also noted in our 850 G3 review. This is a 50°C-rated PSU, so it is normal to have a high OTP triggering point, but we'd be more comfortable if it was closer to 130°C.
There is SCP on all rails, the power-good signal is accurate, the PSU doesn't have a problem operating with no load on its outputs, it doesn't exhibit any coil whine, and there is surge and inrush current protection.
