Electrical Safety Test Class 1
Manufacturer/Model	Pass/Fail
Corsair TX750W	Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and 12V rail 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.

The Corsair TX750W rails held up very well even under full load and easily maintained a level well within the limits laid down by the ATX12V specification.
