Thermaltake Toughpower Grand 750 W 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 listed the unit would shut down, which is the desirable behavior. During this test noise and ripple continued to be at very low levels, but the +3.3 V output dropped to +3.07 V, below the minimum allowed. Efficiency was still above 84%.
