PSU 12v+5v Power Draw

Recommended Posts

Posted · Original PosterOP

hello guys..i need help..my pc currently showing this is that normal?

because something that i connected to 5v molex not working properly..

 

but i took molex cable from side pc(another pc that turned on) its working properly)

then i took the psu swap to this pc still same

the voltages look okay. if you have a volt meter, measure the volts at the molex connector you are trying to use, easy way to tell if it's the psu/connector, or the device you connected, assuming you haven't just tried a different connector.

it looks normal but onboard sensors for these voltages tend to be inaccurate

i have volt meter and tested..same result shown as HWInfo...

but does this voltage is o?k..because i test using voltmeter to my other  pc and i got 12v=11.98v 5v=5.15v.. this combination voltage seem work fine for my 5v device that i connected

i would assume the device you are trying to use is the issue then.

the device said require 5v and the connetor only 5v molex.(2wire)

Those are pretty much spot on voltages.

Means the numbers are as expected for a system.sitting at idle

😐

 

Your not going to find a +12V output that's exactly +12V.  You're not going to find a +5V output that's exactly +5V.

 

You need to stop looking at the PSU as the source of your problems.

yeah im started to believe that the problem not coming from psu..because the device i have been connected to this pc got intermittent but why if i borrow power (molex) from other my cpu work just perfectly fine..and already swap the psu connected to this pc still same problem..now im start thinking my mobo or 24pin mobo doesn't deliver power correctly.

is that possible?

The voltages are fine.

 

It would help if you told us what problem you're actually having, what you're connecting to molex, and what your system specs are.

Yeah, the voltages are not going to be exact.

 

They don't need to be, just close enough that they are within tolerances.

 

Also though voltmeters are not going to be exact in their measurements either as they can be slightly off too, as they also have tolerances/accuracy, drift and if possible calibration that goes for onboard monitoring to high end multi meters.

 

We need more information on what this device is, why it's not working.

 

Troubleshooting wise you need to narrow down the cause, what is the same or different between the two, what parts can you substitute or swap to confirm the fault and so on.
