Question about motherboard voltages

Nylex · 12-30-2005, 10:15 AM

This isn't a Linux related question, but I hope someone can help me here.

System: Asus A7V8X-X motherboard, 300 W PSU, Athlon XP 2700+ (2.17 GHz), 1 GB PC2700 Kingston RAM, GeForce 6600 256MB AGP 8x, 1 20 GB hard drive (for the time being :/).

I have Asus PC Probe running on Windows, it's a utility that monitors temperatures and voltages. My +3.3V is about 2.94 V right now and I'm just wondering if this is ok, or is something wrong (like perhaps my PSU might be going)? I ask because the software had a threshold for this voltage to +/- 10%, i.e. if it was outside this range then the software warns you. I've never seen it go outside the range before today and for the time being, I've increased the threshold to +/- 15% so it doesn't keep flashing at me all the time.

Hopefully someone can perhaps give me some typical voltages or something!

A 300w power supply seems a little on the lite side for that system even without the 6600 video card in it. I believe 300 is the bare minimum for a card of that type you want to consider upgrading the PSU before your parts start getting damaged in other words I think the PSU is getting ready to fail on you because you are drawing too much power from it. Oh here are my voltages.

Thanks for that.
