View Full Version : power supply question

05-02-05, 06:41 PM
I just built a new amd 64 system on a MSI K8N Neo4 motherboard and I have some questions. The fist power supply I used was a cooler master extreme power 430 watt power supply. I noticed the voltages fluctuating a lot when I checked them and the 12 volt was usually only down around 11.76 but it would jump around. The other voltages did the same but not as much. I then bought an Antec 430watt true power. The 12 volt rail is higher but I am still getting fluctuations. Is this normal. The cooler master did not seem to be causing problems but I did not want to take any chances. The antec fluctuations are the following:
V core 1.49-1.51
3.3= 3.28-3.31
5.0= 4.97-5.0
12= 11.90-12.6

Any help is greatly appreciated.

I have built systems in the past but have never noticed the fluctuations. They fluctuate every few seconds

Can you post your system config? The components and such. I'd like to see what is drawing on your psu.
