power supply voltage question

[ronco05]

the 12+V voltage on my motherboard monitor is only showing 10.52V.is this ok or is there something wrong with the power supply?everything is running ok but all the temperature monitors for my cpu and motherboard are jumping all over the place. i am using everest and pc wizard. thanks.

Biostar P4m80-m4 board
celeron 2.13 ghz processor
512mb ram
power supply unknown-came with the case

if i change the power supply will it affect my operating system or files?

absolutley not. Imo its the easiest and most enjoyable thing to change. And btw 10.5 volts is a bad thing. You probably need to chnge it. You could get a nice 450w and be fine

i have three different programs telling me that the rail is only 10.5.what would cause the faulty readings?is it the sensor monitor on the motherboard? i opened up the case and its an AGI 350w power supply. thanks.

Have you manually measured the voltage? You can measure the 12 v. output on a drive power connector between the yellow and black wires. Use a digital meter. They tend to be more accurate than the analog meters.

Hi all,

I've had a similar problem with my (naff) Antec TrueControl550.

The +5v shows +4.6 after post (in BIOS) then drops slowly to 4.19 or so. At about 4.20 the HDD's click off and on and off, etc.

After 10-12mins the voltage levels out at 4.7v and is fine thereafter.

Hard drives have survived this but it looks like an IDE channel is kaput now.

Upgrade approaching soon I guess Minus Antec PSU
