Corsair Professional HX850 850W Power Supply Review

Output Quality (Ripple)

+12V Ripple (CPU Connector)



+12V Ripple (PCI-E Connector)


Just like we saw with the voltage regulation and efficiency testing, the HX850 is a dominating force when it comes to providing a clean output on the +12V rail. Granted, there is a slight difference from one connector to the next due to trace quality, cable length and other factors but this power supply proves itself again to be one of the best we have tested to date.


+3.3V Ripple



+5V Ripple


As expected, due to the relatively low load on both these rails there really isn’t much to report here as the HX850 isn’t even within sight of the ATX specified maximum.
