Load regulation is extra tight at 12V, the most important rail. Unfortunately, this is not the case for the rest rails, where load regulation is loose.

Crossload 2 | 15.9 mV | 17.9 mV | 12.0 mV | 8.5 mV | Pass |
Crossload 3 | 11.6 mV | 12.8 mV | 12.0 mV | 11.7 mV | Pass |
Crossload 4 | 35.7 mV | 15.7 mV | 17.6 mV | 13.6 mV | Pass |
Ripple suppression is decent but not competitive, especially at 12V. In any case, I cannot call below 40mV ripple on the 12V rail at full load and 47C as mediocre.

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?
