Is that voltage OK?

[amdin]

Hello, recently upgrader to Asus b550-f and ryzen 3700x with asus 3070 gpu.

When i enter the bios I see these values for voltage is that OK?

 

Thanks

Yea, those are within normal variance. All good.

Thanks man, can you please give me some info to base your comment, I've found nothing on this topic

No voltage converter can be 100% accurate.

And wall plugs don't have exactly 120v or 240v in them.

As such, the ATX spec has voltage tolerances built in.

The 3.3v line can be as low as 3.135v and as high as 3.465v.

The 5v line can be as low as 4.75v and as high as 5.25v.

The -5v line (which is rarely, if at all) used can be as low as -5.5v and as high as -4.5v.

The 12v line can be as low as 11.4v and as high as 12.6v.

The -12v line can be as low as -13.2v and as high as -10.8v.

As you can see, your 11.98v reading is well between 11.4 and 12.6.

Though I am curious if you've done any overclocking. A 1.4v stock voltage seems a bit high.

Wow! Thanks for your explanation.

I didn't do overclocking, it's just out the box, should i be worried? What can I do?

I'm not super experienced with this kind of stuff, but @ShrimpBrimemight know more.

Thank you!

@ShrimpBrimeplease let me know what do you think about that

Well we usually want to see 12v be 12v. And the 5v be at 5v. 

 

If this voltage reading is the same every day, probably nothing to worry on with a 0.020v droop.

 

But if you see it moving up or down frequently, the PSU is likely not stable and then dont trust it.

 

The reading should be close at idle and load. You can see how the PSU voltage regulators perform by watching it.

Ok, thank you very much.

I have two more questions:

1. What about the 3.3V which is 3.408V?

2. How can I know the values in load if I can't see the BIOS while in load?

 

Again, thank you very very much

3.3v at 3.4v Is ok. Better a touch higher than lower and likely doesnt fluctuate much.

 

12v and 5v can be monitored in HWInfo64 and you can actively use a multi-meter on a spare pcie connector.
