ELECTRICAL SAFETY TEST (Class 1)
Manufacturer/Model	Pass/Fail
OCZ ModXStream-Pro 600W	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.

For your information and for the first time, I have included the no-load voltages with the power supply jumped. You will notice they are actually quite close to the loaded values and give an indication of what to expect should you need to quickly test a power supply.

The DC output voltage load regulation of the OCZ ModXStream-Pro 600W is excellent. The 12V rails are a little higher than other power supplies in this class, but they are still well within the limits set by the ATX 12V specification. No problems so far, so let's move on.
