3R System iCEAGE IA450HP80 450 W Power Supply Review
Overload Tests
Contents
First we tried to see if over current protection (OCP) was active; we maxed out the power supply and the unit didn’t shut down.
Then we tried to pull the maximum we could with the power supply still operating under ATX12V specs. The results you can see below. At this test noise level at +3.3 V was already above the maximum allowed.
