Thortech Thunderbolt 850 W Power Supply Review
Overload Tests
Contents
Below
you can see the maximum we could pull from this power supply. We couldn’t pull more than that because we reached the limit of our load tester. This unit may be able to deliver even more power. During this test, the +3.3 V output dropped even further, to +3.00 V. All other voltages were still inside the tighter 3% range, and ripple and noise levels were still low.
