12v rail drops too much?

post #1 of 7
Thread Starter 
Ok I have a 500watt psu and at idle the voltages on my 12v rail says it's 11.668 but sometimes randomly it drops to about 11.246. Also drops that much when i play cs. Does this mean the 12v rails on my psu is unstable and i need to get another power supply?

1- probably wrong
2- if they change that much...then maybe it is unstable. Check with a multimeter.
3- sounds like a junky generic....just get a decent one and sleep easy.

Then you should ignore it, on-board sensors are off 10/10 times. Get yourself a multimeter if you're worried and test it
