Power Supply Question

Okay, I was on the computer this morning doing pretty much of nothing and AsusProbe starts alarming. First is was telling me that the 3.3Volt reading was dropping to around 1-3V, then the 12Volt reading was dropping to low reading, and to top that off the +5V starting dropping as well. My Vcore is set to 1.776.

I have a Antec True Power 430 Power Supply, with an Asus A7N8X Deluxe MB, AMD 2400 CPU, 1 Gig of Corsair RAM, DVD Rom, Burner, Fan Bus, floppy, two hard drives, two 92mm fans and three 120mm fans (before you ask what I have in my rig).

Now, the whole time this thing was alarming and beeping, the system was running without any errors or lockups what-so-ever. I finally restarted my computer and everything seems fine now. Note: I did turn my system off for about 3 minutes to look at the caps on the MB since I have heard people having problems with leaking caps but found none.

So....was Asus Probe 2 just freaking out or do I have a serious power supply problem. Has this happened to anyone else? It hasn't started freaking out since I rebooted, in fact everything is stable as can be. Also, my temps were absolutely normal during all of these strange voltage readings.

Thanks for any input.

I've seen PC Probe lose control of itself over fan speeds, but never voltages. Given the power supply you have, the fact that there were no other signs of a failing PS and you went the extra mile and looked for a motherboard problem, I'd bet it was a software glitch with PC Probe. As an isolated incident I'd probably not worry about it.

If you were using the Big Value Power Supply from Shifting Sands of Omaha, I'd feel different.
 
I've seen Asus Probe make wild-eyed claims about my voltages. I trust it about as far as I can throw it, and I don't have a good throwing arm either 😀 Use a digital multimeter for a reality check.
 
Thanks for the input folks. I'll continue to watch it and I'll install MBM5 again and use that as my monitoring device.
