Electrical Safety Test Class 1
Manufacturer/Model
Pass/Fail
Thermaltake Litepower 450W
Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0, and both 12V lines in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

No problems here. All voltages well within the ATX12V V2.2 specification from zero to full load, giving excellent DC output load regulation.
