Fluctuating Voltages

[FollowerCTO]

I have an Antec 480 watt TruePower powersupply, and it is a good powersupply. But, I'm getting fluctuating voltages and a severe undervolt ranging from 1.67 to

1.725 on my cpu voltage. My voltage is set to 1.775. Could it be the powersupply?

Has anyone else had any issues with Antec TruePower? I also live in a dorm room in one of the older buildings on campus. I could be the power going into the building. Gives me an excuse to buy a UPS

It could be your PSU, or it could be your board. Some boards have bad under-volting problems, but I've never really heard of a NF-7 having them. What do your rails look like?

Well my p4p800 has a severe vcore stability problem that is well known. At my current 1.675vcore, at full load my voltage drops down to 1.602v according to cpuz and mbm5. My first guess would be that your MB is the culprit. It shoudn't be an issue if your comp is running fine. I'm completely stable at 3.5ghz with my 2.8c even with the huge vcore dive under load.

 

I seriously doubt that the Antec is the problem. They make the best psu's along with enermax. I'm using the antec truepower 550w and it is rock solid. But just to be sure let us know what your other 12, 5 and 3.3 rails are so we can get a better idea of what your overall power situation is like. If you could give high/low numbers from mbm5 that would be even better.

Here they are, to give you a better idea. I'm starting to think it is just the power being fed to the powersupply. this IS an old building. I also changed my voltage and clock settings back to normal (default core, 2500 to 3200).
