Transient Response
20% Load – 20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.070V | 11.913V | 1.30% | Pass |
| 5V | 5.065V | 4.673V | 7.74% | Fail |
| 3.3V | 3.356V | 3.223V | 3.97% | Pass |
| 5VSB | 5.084V | 5.051V | 0.66% | Pass |

The 5V rail drops low. The 1100W model also had the same problem.
Transient Response ATX v3.0 Tests
The PSU passed all ATX v3.0 transient response tests with success. The 12V rail drops close to the lowest limit of 11.04V, but remember that I hit it with a 2600W load, and this is an SFX unit!
The 200% transient test shows this platform is hugely stressed to meet the tough ATX v3.0 requirements.
