Corsair HX1000W Review

Testing:

Electrical Safety:

 

Electrical Safety Test Class 1
Manufacturer/Model	Pass/Fail
Corsair HX1000W	Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and all two 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:

The DC output load regulation of the HX1000W is excellent and I have to say almost perfect. That says it all really!
