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: 31.2 A (156%) 3.3V: 29.85 A (144%) 5VSB: 5.6 A (224%), 4.712 V|
|OPP||975.72 W (130.1%)|
|OTP||Yes (main transformer @ 115 °C )|
|SCP||12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes|
|PWR_OK||Does not function correctly|
|SIP||Surge: MOV Inrush: NTC Thermistor & Bypass Relay|
OPP is set quite high. However, the PSU doesn't have a problem delivering such high power levels under normal operating temperatures. After all, rippled suppression and voltage regulation are both handled well. On the other hand, OCP at 5VSB should be set lower since, with 5.6 A, the this rail's voltage level goes out of spec, registering 4.712 V.
Over-temperature protection is present and works properly. The same goes for the short circuit protection. Unfortunately, the power-good signal is inaccurate; it's in an "on" state while the rails are out of spec. Finally, the PSU doesn't have a problem with zero load on its rails, and you do get surge and inrush current protection.
