50% Load -20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.049V | 11.905V | 1.20% | Pass |

The transient response is decent at 12V but needs improvement at 3.3V, where the unit doesn’t pass the second test since its voltage drops below 3.14V.
Transient Response ATX v3.x Tests
The PSU passes all ATX v3.0 transient response tests, but the 3.3V rail drops low in the 200% load test.
In these tests, the 12V rail drops low. The change in caps on the secondary side is the main culprit.

If this were to be evaluated on a tier list, would it be tier A or tier B? And the 850w model is available in my country for 150 dollars, do you think it is worth buying?
I don’t do tiers, I do best PSUs with actual ratings 🙂 Please check the corresponding article
I think it is expensive at 150 dollars, always for amazon.com standards/
I think so too, the merchants in my country like to give high prices. I guess this is what they call the free market.
i think ELITE the best tier 2 caps on a market, i found out ASUS PRIME PSU was using non Japanese Caps but used ELITE caps as a bulk Caps
