Hi again all, I finally got all the parts and built my system. It booted up np the first try but I have some funky voltages. I haven't got a response on my PSU forums so I figured I'd post here as well to see if any of you had an idea of what my problem here is.

Hi,

I just finished building my new system, and thankfully it booted up np the first try. However, I did notice that on the back of my PSU two of my lights are yellow and the other is red. Now, I decided to check the voltages in my BIOS and I had found that the 12v and 5v rails seemed to be about right on... but... the 3.3v rail was running at 2.44... I decided to tweak the voltages slightly on the 12 and 5 and got them to be right on using the dials in the back but no matter what direction I turn the 3.3v rail it does not update in my bios. Also, all of the lights are still not green.

Maybe this is a stupid question but what am I doing wrong? I've limited use of my system to very short time frames because I am worried about damaging components from the wrong voltage ratings. I also tried plugging the system in at two seperate rooms to see if it was the wall jack. Thanks in advance for any advice you can give.

Dan

Ok, I have an update on my voltage situation. I pulled out my handy DMM and started to measure some voltages becuase I questioned the accuracy of the mobo readings. So... the 12V rail was exactly that, 12 volts. Now, the 5v was a tad off so I adjusted it to 5 even as well. Finally, after measuring the 3.3v rail (using orange wire of ATX and ground) I found that it was 2.54V. Again, no matter what direction I turned my dial to adjust the voltage, it didn't budge.

Just for a quick sanity check I used the Blue "P4" (not the P4+ but according to the label they are the same) connector in for the 12v atx slot. I used the ATX in the mobo obviously and the "E" plug for a total of 24 pins into the power slot.

|----20ATX----||-4E-| <-- so it looks like this.

I'm pretty sure everything is hooked up right, I'm lost as to why this is happening. Again, thanks in advance for any tips.

you def seem to have something screwed up

An LED sits below each of the three adjustment dials; a green light indicates voltage is within ±5% of optimal, a yellow light indicates undervoltage, and red indicates overvoltage

The 20/24 pin main ATX has an adjacent slip-on (only one way) 4 pin black molex that has yellow orange black red. This has to go on all connected, which gives 4 total orange 3.3V

There are 2 blue molex 4 pin yellow yellow black black connectors - these dont go to ATX main. One of these goes to CPU 4 pin square female - only goes on one way.
And the 7800 gets its own molex, supposedly its redundant if you use full 24 pinout ATX main

I would get this all straightened out before you start frying things
Its either wrong wiring or bad PSU
