Transient response (transient behavior)
The transient response is excellent at 12 V, where it is most important. It is also quite good on the other rails.
20% Load – 20ms
Voltage | Before | After | Change | Pass/Fail |
12V | 12.104V | 12.039V | 0.54% | Pass |
5V | 4.998V | 4.914V | 1.68% | Pass |
3.3V | 3.331V | 3.260V | 2.14% | Pass |
5VSB | 5.024V | 4.957V | 1.34% | Pass |
50% Load -20ms
Voltage | Before | After | Change | Pass/Fail |
12V | 12.095V | 12.023V | 0.60% | Pass |
5V | 4.994V | 4.910V | 1.68% | Pass |
3.3V | 3.326V | 3.255V | 2.15% | Pass |
5VSB | 5.002V | 4.938V | 1.29% | Pass |
Transient Response ATX v3.1 Tests
The power supply passes all ATX v3.1 transient response tests.
The 12V rail keeps its voltage very high in the 200% load test. Only the SF850 performs better here, but it has a 150 W lower capacitance, so the applied load is 1700 W, while the transient load on the SF1000 is 2000 W.
