CS650M ticking sound and extremely low voltage on +12V?


Recommended Posts

Recently purchased CS650M for my desktop at work and I've been having nothing but issues with it.


There is this ticking sound coming from the power supply for which I can't identify if it's the ventilator or something else.

It comes and goes, sometimes it's very loud, othertimes I can hardly hear it.


My biggest issue is the voltage output on +12V rail :


+3.3V = 3.344V

+5V = 5.130V

+12V = 11.880V


This reading was taken in BIOS.


Doesn't Corsair test their products before shipping?

11.880V while IDLE is really really terrible, doesn't even come close to this : CS650m Voltage Regulation and Efficiency Measurements

Yep. Voltages measured in the BIOS or software are dodgy at best.


Even if they were correct, nothing wrong with +11.88V on the +12V rail. You can drop to +11.6V and still be within spec. Spec is +/- 5%.


As for the clicking noise... hard to say without knowing where it is coming from. But if it's the fan, I'd definitely RMA it.
