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: 31.5A (143%) 3.3V: 34.6A (157%), 3.15V 5VSB: 3.7A (123%) |
| OPP | 1105.4W (130%) |
| OTP | (120°C @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Operates properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor |
Over-power protection is set quite high given this PSU's thermal output under high loads. Thankfully, over-temperature protection kicks in to protect the SPR-0850F-R if its fan can't keep up.
OCP on the minor rails is set high, especially at 3.3V, while at 5VSB it's set at a normal level.
There is short-circuit protection on all of the rails, and the power-good signal is accurate (though the hold-up time is pretty low).
