Hello, i have a question about psu voltages.
First of all, i have a rmx750x.
In the 3.3 i´m getting 3.248. Is this ok? or there is something wrong?

Also, sometimes that voltage varies, a litle bit during less than a second, it goes to 3.268 and then 3.248 again.
Also, the 5.0 rail goes to 4.980.
Is there something i should be worried about?

That is normal and nothing to stress over as long as it's in the + - 5% range of the rail voltage. Better power supplies will have tighter voltage variances.

What are you using to measure the voltages?

If your PSU's +3.3V rail is outputting between +3.14 and +3.47 Volts then it is considered within spec.

If your PSU's +5V rail is outputting between +4.75 and +5.25 Volts then it is considered within spec.

Yes it's completely normal to see slight variations in voltage over time.

I mean, no permanent changes.
As i said, something like a 0.02 drop for a second or so, the go back up.
Thanks.
