Transient Response
20% Load – 20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.135V | 11.972V | 1.34% | Pass |
| 5V | 4.995V | 4.914V | 1.62% | Pass |
| 3.3V | 3.265V | 3.141V | 3.80% | Pass |
| 5VSB | 5.059V | 5.011V | 0.94% | Pass |
50% Load -20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.109V | 12.010V | 0.82% | Pass |
| 5V | 4.987V | 4.901V | 1.71% | Pass |
| 3.3V | 3.257V | 3.128V | 3.97% | Fail |
| 5VSB | 5.022V | 4.973V | 0.98% | Pass |
The transient response is good at 12V, 5V, and 5VSB rails, but there is an issue at 3.3V because this specific rail has a low initial voltage level. If its voltage were close to 3.3V, it wouldn’t fail in the second test.
Transient Response ATX v3.0 Tests
The PSU meets the ATX v3.0 requirements.
The 12V rail’s voltage levels are at satisfactory high levels in these, demanding tests.

Hi, glad to find review of this one, thanks! If you were to choose between:
a/ Thermaltake GF A3 850W for 115 EUR
b/ MSI MAG A750GL PCIE5 for 98 EUR
which one would you choose? The PC is i7-11700 + RX 6750 XT.
I would probably go for the GF A3 unit.
Thank you for the reply!
Well, I know this is problably the type of questions you really don’t like to answer, but I’ll be most probably changing 6750 XT to 7700 XT in the shopping list, hence budget for the PSU gets lower… What would be the cheapest 700W+ PSUs I could get and would still be decent? I would prefer semi-modular or modular.
Hi there, i have a question i know the anwser but i want to ask you, the A850 is very cheap now like under 100 Euros, and the SuperFlower 1000w XP is 180e. The construction, quality is very different? Should i go for the Super, or the A850 is enough? i have a system of 550W, and i will buy a new gpu from the 5000 series. Thank you!
The A850 if it covers your needs and you don’t need much Wattage. Now if you go for the 5080 or 5090, definitely the 1000W SF unit.
