I was just wondering if someone wouldn't mind looking at my voltage readings according to EVEREST Home Edition? I just installed a new graphics card so I am checking all the voltages out.

CPU Core 1.26 V
+2.5 V = 3.15 V
+5 V = 4.76 V
+12 V = 11.65 V
 
Really better off using a digital multimeter. Software based voltage reading can be way off. That said, those do look to be on the low side.
 
I have an FSP AX450PN, it is a 400 Watt PSU. I'm running an a64 3800+ Orleans on an Asus m2n-sli deluxe motherboard, 2 gigs ddr2667 memory, 2 HDD, 320MB 8800 GTS, pci sound card, and an optical drive.

What does it mean if the voltages seem on the low side? Do I need to turn something up?
 
Thats interesting, the software has it showing a +2.5V and not +3.3 V, so what are my low voltages a product of? Aren't there voltage settings I can adjust in my BIOS?

Okay so I went into my BIOS and got these readings:
VCore = 1.42 V
3.3V = 3.35 V
5V = 5.10 V
12V = 12.49V

Should I trust EVEREST Home Edition or my bios voltage readouts?

You can adjust vcore, but that isn't the real troubling one. The other 3 (3.3v, 5v, 12v) are not adjustable. They can end up low for a number of reasons. The PSU might be overloaded, or simply aging, or could be getting poor or inconsistent power at the wall. How old is it? Newegg shows that model as a 450 watt supply with dual 12v rails, each with 18A max available, so it /should/ be able to handle that system, but that doesn't mean there's not something wrong with it. That said, are you having any kind of instability or anything? If not, they are software readings, take them with a grain of salt unless they get /really/ low and just don't worry too much about it.
 
Your positive voltage rails should be within a +/- 5% tolerance range. According to your first measurements, your +12V rail is at 2.9~%, and your +5V rail is at 4.8%.
For your second reading, your +12V rail is at 4.1~%.
