[SOLVED] 12v Rail Fluctuation

[rickypicky5]

According to my BIOS as well as HWINFO, my 12v rail is fluctuating between 12.24 and 12.312. Mostly it's staying at 12.312.

It's a new PSU - Seasonic Focus Plus Gold 750W.

Is this acceptable or should I be concerned?

It's perfectly normal , no need to be alarmed.

seams in the specs could you post a picture of hwinfo sensor page and does voltages match bios readings .

Could not post a pic of my hwinfo? Not sure why.

Something went wrong. Please try again or contact your system administrator.

You need to upload the screenshot to a site like imgur.com then post the link they supply into your post here.

That was from yesterday. Today is similar only the min is 12.096. So the range is 12.096 to 12.384.

Software readings are unreliable. Try using a multimeter instead.

It doesn't matter. Both get their readings from the same IC on the motherboard and both are horribly inaccurate.

Assuming the readings are accurate, is that range (12.096 to 12.384) okay?

I'm not going to assume those readings are accurate because they're not.

But if you were using a DMM and saw that fluctuation, I would say that's a huge fluctuation as the voltage should only drop about .1V from idle to full load. But the voltages are withint the +/- of 5% allowed by the ATX specification.

But that's neither here nor there because the readings aren't accurate. You might as well use a random number generator to get your voltage readings then the IC on the motherboard.

what is the value bios report for it and why your cpu fans run in at 4,000 rpm and the others are as low 500 to 600 rpm see also that in bios .
