Speedfan showing +0.0 volts on +3.3

Hey i'm new to this forum, and wasn't 100% sure where to post this....

But anyway, I just bought a Codegen 550W to temporarly replace my old 300w, and when i goto speedfan under +3.3v it shows +0.0v, and I would like to know why, because i have never seen this before...is the PSU defective...or is something else wrong with my system?

PC specs are:
Win 7 HP 64 bit
Intel Core Duo 2 e7500 2.93 ghz
4 GB Kingston DDR3 PC 10700
WD Blue Caviar 500GB HDD
Nvidia GT 240
Codegen 550W PSU

My temps are good and never reach near 50 under load.

  1. Not sure why this was posted in Windows 7 forum, but Speedfan's ability to correctly display voltage is suspect at best. Go into the system BIOS and check under 'hardware monitor' or similar for more accurate voltage readings.
  2. Yeah, I wasn't 100% sure where to post this, but I checked my BIOS and it's locked up by Dell...that's why I was using another program to see my voltages. I've tried HW Monitor Pro and it doesn't show +3.3v anywhere. Would there be a better program to use besides the 2 I mentioned?
  3. Try hardware Monitor Pro and see if it shows up.

  4. I've tried it, nothing.
  5. The BIOS or MB may not monitor the voltage.
