+12V more than 13V

I have an A7V333 motherboard with an AMD 2100+ chip installed.

The chip has overheated once and i bought a new microchip fan to replace the original fan.

Now, the reading for the +12V is roughly around 13.13V.
How does this affect my PC?

There's nothing wrong with my PC so far, but I'm worried if anything goes wrong.
 
I'd say it's on the very edge, if not over. What psu(brand as well) do you have and what are your other system specs ?.
 
I have

two PC2100 Kingston RAMs
Albatron GeForce4 MX440
2 HDD:-Maxtor 40G 7200 rpm 2 MBcache
WD 80G 7200 rpm 8MB cache
Win XP pro
 
By the book, your voltage shouldn't be any more than .33v off from its rating. However, I'd say up to .5v difference is tolerable (though not desirable). In your case, you should probably replace that PSU, it could wear down your components over time causing them to weaken and eventually die. Don't be discouraged, try out my favorite place to pick up a new power supply: http://www.mrtechus.com
They've got a pretty nice blue-iodized, 600-watt unit for something like $35. I've used 'em in a few client's systems so far, and they've been great. Just whatever you get, make sure it's UL approved. There are some funky chinese PSUs out there that are more trouble then they're worth... :(
 
Personnally I'd go for a Antec True Power 430W or 480W. They're known to be reliable. You'll pay more but at least you'll know that every penny is worth it.

The rated supplied power doesn't mean anything. I bet you anything that a Antec 350W can beat many generic 450W anywhere, anytime.

whatever you do, don'T try to save bucks on a power supply, it's one of the most important parts of a pc.
 
Inthe event that the voltage reading isn't being displayed wrong, you can also double check the voltages with a multimeter.
 
If it comes down to PSU replacement and you are willing to spend some money, I personally prefer Enermax to Antec . In my experience with them, I've found Enermax to be more reliable. However, Antec still makes a very good power supply, and Enermax is a little pricier.
 
I really have no idea how this would affect the PC performance..
Can anyone enlighten me on this??

I met a computer expert. He said that the Asus PC probe may report the voltage wrongly.. Also, he told me to try using another power supply before buying a new one. If the readings are still the same, he told me that the motherboard is konked.

Is his accusations baseless?

My BIOS reports the voltage as 12.66V. is that ok?
 
It does affect the performance.

Not too long ago I had a Antec PP-352X (350W) and a 9800 non-pro. I flashed the card to a pro BIOS and the computer was very slow but once I flashed back, everything was ok. So I bought this Antec 480W and now everything's fine.

So the psu does make a difference.
 
Now that you mention it, Asus PC Probe did give me trouble regarding voltage...but this was with my A7V (it's almost 3 years old), and I simply didn't use it. I'd thought they'd fixed it, but it looks like it's not. Personally, I don't keep an eye on my gauges that often, but Asus is known to report stuff higher than it actually is, most notably temperature. Before swapping out the PSU, try a different monitoring program. Motherboard Monitor is pretty good from what I hear.
 
I've tried my WinME (I have multiple OS). It's been a long time since i've used it but it works fine.. I guess it's my WinXP which isn't working well, i guess..
thx for the help guys, I've 1 less worries to worry about.
