While the performance of the ST35F is not ground-breaking, it is acceptable for a unit of this output and price range. The voltage lines are kept well within specifications, even if there are constant fluctuations, they are within tolerable limits. The 12V lines could be a little steadier but they are not problematic.
The efficiency of the ST35F is merely average if compared to high end PSUs, but it is fairly good for a unit in this price range. It does deliver the promised 80% efficiency under normal load (40%-60%) but the efficiency goes down as the load increases, due to the generated heat which reduces the performance of the unit. The tiny metal blocks which are supposed to be heatsinks do not help much when the unit is working at above 75% load, resulting in relatively high exhaust temperatures from a unit with this kind of power output.
