Ok, I have a bit of a concern with the power running from my power supply to my motherboard. I have a
1.2 ghz AMD Athlon T-bird
64 mb Geforce 2 GTS Pro AGP card
Virge 1 mb PCI Video Card (For second monitor)
40 gig Maxtor ata 100 HD
12 gig Maxtor ata 2 HD
Soundblaster Live! 5.1
Ok, I just fried my last power supply so I'm a little worried about the new one I bought. 300 watt supplying power to all that and about 3 fans, and a baybus I made that controls two thermometers. The main concern I have is concerning the +12 -12v line. I checked it before my other power supply fried and it was running at about 13 volts, 13.2 when it would shut off. The one I just bought is running at about 12.8 to 13.0 volts. I've tried returning my processors clocking speed to normal, checking for groudnings, unplugging devices, blowing dust out, praying, everything I can think off. Here is my question:
1) Is this a problem/big deal? If so:
2) How can I fix it?
Any help would be greatly appreciated! Thanks for your time!!

12.5 volts is actually pretty high for a loaded system 13 volts is pushing the limits of regulators on board. Right now my 12 volt line is at 11.85 volts with 2 40 gig HDD's 1 cdrom, 1 CDRW 3 80 mm fans and a huge copper core HSF.

Ok, well, any ideas on how to get it down? I'm not sure why it's drawing so much power out of the power supply. Should I hook up a second power supply to run some different things?

First thing to do is make sure the voltages are being reported correctly. If you have a VOLT OHM METER handy measure the voltages directly from the PSU than compare the readings to what the BIOS monitor or software you are running is reporting. I have noticed that there can be as much as 10% + or - difference.
