Weird Issue, PSU or MOBO

I have an antec trueblue 480 which isn't more than 9 months old. For a while now, I can remember since when, I've had to raise the cpu voltage from stock 1.65v to 1.725v in order for the computer to boot to windows/be stable when running cpu intensive applications likes games etc. If I leave the cpu voltage at stock and I monitor the voltage with abit EQ it seems like there is a significant voltage drop when I run cpu intenive stuff which causes a crash or computer reboot.

I emailed abit tech support previously and he suggested it may be that the 3.3v line is not supplying enough current so i have to raise the cpu voltage to compensate. I dont understand how this could be when the 3.3v line is like 30amps. If that was the case, the current would have to pretty low wouldn't you think. This is the only weird issue I've came across. Everthing else in my computer seems to be running perfectly stable as far as power goes.

What do you think the problem is? PSU or mobo. (mobo is about 2 years old)

Could it be bad capacitors not keeping up?

What do you think???


Thanks
 
The CPU voltage on an Abit NF7-S is regulated by the 5V. Not the 3.3V. o_O

Sounds like a board issue to me.
 
thanks for the input. I think i'll be upgrading in the next little bit hear and didn't want to have to buy a new PSU if i didn't need to.
