Electrical Safety:

 

Electrical Safety Test Class 1

Pass/Fail
Thermaltake Toughpower XT 850W
Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and the 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 Thermaltake Toughpower XT 850W I reviewed is a member of the small group of power supplies that cannot be "jump started" with no load present so I had to introduce a small 31W load to the 12V rail to get the power supply to run. I therefore could not get any no load rail voltage for the 12V rail and you will see that the graph starts at 31W; it's not zero load but it's near enough!

Perfect! The Thermaltake Toughpower XT 850W gave near perfect results in this section. The 3.3V, 5V and 12V rails held solid from 31W to 850W loading as can be seen from the straight lines on the graphs.
