OCP is highly set at 12V in cold conditions, but since it drops below 130% at high temperatures, I won’t mark it down as a negative, given the platform’s capabilities. OPP is also close to 140% at low temperatures but drops notably at high temperatures, effectively protecting the PSU. The 5V rail has its OCP triggering point logically set, but this is not the case for the 3.3V rail, which exceeds 30A without triggering!
OTP triggers at a relatively low temperature on the 12V heatsink, but this makes perfect sense since the latter one doesn’t come in direct contact with the 12V FETs. Lastly, all other essential protection features are present.

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?
