Corsair AX850W Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. Because of its incredibly overspec’ed components, we could pull 1,000 W from it, but efficiency dropped to 80%. Here we were limited by our equipment, which can only pull up to 1,000 W from power supplies. So, this unit may be able to deliver even more power.
