3.3v spiking, PSU or Bios fault?

post #1 of 7
Thread Starter 
Hello folks. Need help to determine the culprit.

Here are my specs:

MB: Asus P8P67 Pro
CPU: i7 2600k
GPU: Nvidia GTX 560 Ti superclocked
RAM: G.skill 4gig Ripjaw X ddr3-1600
PSU: A 4-5 year old OCZ GameXstream 600w

Asus Suite II has been gracious enough to log its alert if this will help.

I've heard a thing about P67 monitoring isn't accurate and the surge protection will kick in. I don't feel like taking off surge protection, but if there's any news about it, it would be helpful.

And my PSU is being reused and is quite old, however, it didn't have a problem with it until I put in new parts. Is 600w enough? I think I will get a new PSU, but if it isn't the PSU's fault, I'd rather fix any other issues first.

Also, I don't have any handy tools to determine if the PSU is faulty or not.

Software monitoring in general is worthless. Check with a digital multimeter--you can check the +3.3V through the back of the 24-pin connector.

Oh man, I did say that I don't have that stuff to check... guess it's the only way?

You can get a DMM for dirt cheap if there's a Harbor Freight Tools nearby; I think they have the Centech model on sale for $3. If you don't have an HFT nearby then Walmart will usually have the same thing for $15-$20.

Agreed, never base readings off software monitoring. Dont know where you are located but your local electronics store should have a digital multimeter for 15-20 bucks

EDIT: sorry didnt see above post ^

So, if my PSU is alright, and the monitor is tripping the surge protection, what do I do then?

If surge protection works based on monitoring, and monitoring is faulty, there is really only but 2 choices.

1) Deal with it.
2) Turn off surge protection.
