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: 110A (110%) 5V: 32.15A (128.6%) 3.3V: 32.5A (130%) 5VSB: 4.7A (156.7%), >100mV ripple |
| OPP | 1427.53W (119%) |
| OTP | ✓ (135°C @ secondary side) |
| SCP | 12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓ |
| PWR_OK | Does not function properly |
| NLO | ✓ |
| SIP | Surge: MOV Inrush: NTC thermistor & bypass relay |
OCP is set up properly on all of the rails except for 5VSB, where it should be much lower (with 4.7A of load we measured over 100mV ripple). Over-power protection is configured reasonably well, while there is short circuit protection on all rails, as expected from a modern PSU.
Unfortunately, the power-good signal isn't accurate; it drops after the rails go out of spec. This is downright unacceptable in a high-end PSU, and we can't understand why CWT didn't tune it properly.
