Seasonic SS-300TFX Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. If we tried to pull more than that the total wattage being pulled started to decrease instead of increase. Also during this test noise level at +12 V outputs were above the maximum allowed (at 150 mV – 160 mV range). Both symptoms show us that the unit had already reached its limit.
