PSU -12V problem

  Gonzo1452 15:02 14 Mar 2010


My psu is running the -12v rail at around -7v

Is this a problem? This reading was obtained using CPUID HWMonitor, i have checked in the bios but it only lists the + values.

Any advice would be helpful please.

The psu is a 450w supply

Thanks in advance

Sorry i should have added

All the + values are fine as are the other - values.

I don't know the technicalities, but as long as your PC is not presenting you with any problems, I would not worry about it.

Hi Technotiger

Thanks for your answer, i have not noticed any problems but as it was a new pc i was wanting to check, my last pc held all the values in the bios and was accurate.

Any other opinons are welcomed......

PC does not use 12- only +

Thanks Woodchip.......

Why does programmes like HWMonitor check for it? Is it just a throwback to old units?

My last PC listed it in the bios

Thanks for the input.

This explains a bit more.

-12V is used in serial ports - but they are very voltage tolerant anyway - and how many use a serial port nowadays.

Thanks DieSse

In that case i'm not going to worry about the PSU as the rest of the voltages seem perfect.

Thanks for everyones input.
