Testing:

For more information on how we test our power supplies, please browse our testing methodology.

Electrical Safety:

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.

DC Output Voltage Load Regulation:

Mains Input Voltage 110VAC

*DC Output Voltage Load Regulation*
AC Supply = 110V / DC Load = 0W
