Testing:

TX850V2

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

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and the 12V rail(s) 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

The Corsair TX850V2 power supply produced a great set of results in this section. The regulation was excellent with little voltage drop from zero to full load as shown by what are virtually straight lines on the graphs. No problems here so let's move on.
