I get it. This is a 650W ATX v3.0 unit, so it must be able to provide more juice. But the 12V rail kept going in cold conditions, and I had to stop it at some point. It stopped at nearly 148% in hot conditions, which is pretty high, but load regulation and ripple were in control. The 5V rail has a properly set OCP, but this is not the case for the 3.3V rail!
OPP is sky-high in cold conditions but reasonably set at high temperatures. Lastly, OTP looks low, but it is because of the 12V heatsink placement.
All in all, this is a low-capacity PSU, beefier than the standard components because of the ATX v3.0 compatibility, so they allowed for a much stronger 12V rail.
