In Win Commander 850W Power Supply Review

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
In Win Commander 850W	Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and all four 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 as planned.

The DC output voltage load regulation of the In Win Commander 850W is excellent. The graphs show the 3V3, 5V0 and 12V rails to be more or less a straight line from zero to full load at 110VAC and 230VAC. No problems here, so let's move on.
