is my power supply giving too much voltage to my pc

[david2017au]

I was talking to some people and they said it is possible that my vs 650 could be giving more voltage to my pc is there any way to see if it is

No. The PC will only draw the power that it requires. It doen't matter if your power supply is 1000 watts or 650 watts. If the system needs only 200 watts, that is what it will draw.

It is a good idea to match the power supply to your system though. It will be a bit more power efficient that way.

Any monitoring software will tell you the voltages. The system BIOS will as well. https://www.cpuid.com/softwares/hwmonitor.html

Only a malfunctioning power supply would be supplying too much voltage. If your friends are saying your power supply is too large, no, the computer will only consume what it needs.

The wattage provided is a maximum output. It will only output that much if there is a load to consume it. Exceeding that rating can cause the PSU to shut down gracefully. Not so good power supplies may fail spectacularly, explode, or catch fire. Though Corsair are usually pretty good about failing gracefully.

ATX spec roughly:
5V +4.75 V to +5.25
-5V −4.50 V to −5.50
12V +11.40 V to +12.60
-12V −10.80 V to −13.20
3.3V +3.135 V to +3.465
-3.3V +4.75 V to +5.25

Yes, but you'll need a voltmeter or multimeter to check accurately.
You can use a Win app that monitors voltage or check in BIOS, but those readings may be slightly off.

Software voltage is often wrong. You can be over voltage and under by up to .5v without issues (for the most part). But software is usually way off. but 12.6v is fine for the 12v rail even if its from software.

is there any way to see if it is

Yes, you can measure the voltage using a multimeter. There are also the meters that plug into the outlet with an outlet on the front.

Yes, you can measure the voltage using a multimeter. There are also the meters that plug into the outlet with an outlet on the front.

Those only measure the primary side of the PSU. The OP can't read his PSU's output voltages with those. Watts, yes. But even that is before power factor is considered.

is this one somewhat accurate HWinfo64
It not about it being too big it's about how people are telling me since the vs series is bad it will slowly give too much voltage to my parts

 

[terry4536]

Sure it is fine. I use HWmonitor myself.

Other monitoring apps that I use are CPU-Z & GPU-Z.

Yes, the VS series is the low end class of the (Corsair?) line of PSUs. But it isn't necessarily 'bad'. Is it the one with the gray label or green?
The only way the PSU will output out of range voltages is if the regulator module(s) fail. Not all that likely.

 

[david2017au]

it has a black label

 

[clutchc]

it has a black label

Yeah, that's the newer, better line of Corsair PSUs. The VS is their low end model, but if the voltage is within tolerances, it should be fine. Check with a Windows app if you want. But to be more accurate, you'll want to use a voltmeter at the 24-pin and CPU 4/8 pin. Use the list that Eximo presented to verify you are within tolerances.

Are you having some kind of issues that make you think the voltages are low?

 

[david2017au]

So my vs power supply is their newer model
And there is no issue saying that it too low

I didn't say there was no issue. I said you would need to check the voltages if you had a concern. But I doubt there is anything wrong.

ok thanks
