I've recently upgraded my graphics card to a ti4600, and my old psu was only a 300w. I purchased a new case and psu, an Antec SmartPower 350w. After getting everything moved and playing for a bit, I noticed a warning signal I had never had before. I've been running Asus Probe in the background all the time, just to monitor system temp, but it is now flashing warning on the -12v range. It constantly runs between -13.0 to -13.25. I installed MBM 5 after reading on this board that it is a better system monitor, and I get the ranges posted below. I have no idea if this is bad or not, just wondering if someone could give me a little info on this.
Voltage Readout +3.3v : 3.568
Voltage Readout +5v : 5.02656
Voltage Readout +12v : 12.0992
Voltage Readout -12v : -13.21216
Voltage Readout -5v : -5.146272
I wouldnt worry about it.
The negative voltage lines barely carry any power, (1 Amp max) and often vary considerably.
Its just the analprogram kicking up a stink.
Really the main voltages you have to worry about are the ones that carry all the load, the 5v and 12v lines.
With your values you will notice that they are very close to what they should be. You have a good quality PSU. :smile:

I'm planning to upgrade my system. I am confused on how important the 12v rail is. This is how I understand it from Amd's "Building a System" pdf.
AMD XP2100 email@example.com
KT400 mobo 12v@.30amps
My CDRW firstname.lastname@example.org
can't find specs on my toshiba
Maxtor 60gb 12v@1800milliamps at startup=1.8amps?
Maxtor 20gb 12v@2500milliamps at startup=2.5amps?
4 Case fans .25amps each email@example.com
So if i add this up i get 15.99amps. My enlight 340watt outputs 15amps on the 12v rail. So I will need a bigger PSU right? I read this review http://www6.tomshardware.com/howto/20021021/index.html
and they reviewed 21 PSU's and had a system with 4 HD's on raid array (that's almost 8amps right there at startup) and had many 300 to 350 watt PSU working with the same specs as mine. Also my current 12v rail will move from 12.43 to 12.25 depending on the load my 5v moves from 5 to 4.97. I'm wondering how to read this, is this what the PSU is putting out? So higher is better?
