The transient response is good on all rails.
Transient Response ATX v3.0 Tests
The PSU meets the ATX v3.0 requirements. It would be nice to see above 3.2V at the 3.3V rail, though at the 200% transient load test.
The 12V rail performs well in the ATX v3.0 tests, keeping high voltage levels.

Hey, I think Thermaltake is doubling down on “cheap” capacitors, and will be using their brand name to sell fake premium products to consumers. This is their newest ATX 3.1 with photos of the board:

Looks like they even have 2 variants under the same model…

Cheers, love your reviews.
Hello! I am currently choosing between this model and MSI MAG A850GL PCIE5 850W. As far as I understood, they are pretty much similar in terms of performance. The price is the same as well. The only difference I spotted is the noise level. Am I right? Which one would you choose?
