Do I need a new psu?

techquest

So if it worked fine for months don't you think it is still fine.  As for someone telling you it's dangerous, where is their evidence for such a statement. IMHO that is a peace of advice you can firmly file under G for garbage, I can't find any evidence to support those views.

1. It's not your product.
2. Do you think Cooler-Master would be selling product and providing 3 years of warranty if their product was crap?

3. You can listen to jonnyguru if you want but my advice would be to just ignore that article. You are getting yourself wound up for no reason whatsoever. You have already confirmed your PC has worked fine for months with no issues. So I imagine it will go on for a number of years with no issues, at least not down to the PSU.

It's time to stop fretting now and carry on using your PC without worry.

I'd agree generally. There's a weird culture around PSUs with some people willing to swear blind that only the high end ones are worth having without being able to provide any practical reason why.

For a few uses it's actually justified, for example it can make the difference between eeking out a little more overclock for those who want to max out their benchmark results.

For anything else... Well, there just isn't the evidence that the high end ones are anything other than luxury products, offering minor real world improvements for lots of money.


Although I'd disagree about disregarding the Johnnyguru tests, and Coolermaster in general. Coolermaster has sourced somewhat questionable PSUs for their budget model at several points in the past, and I can well believe they picked one that doesn't meet the ATX spec.

But not always and if yours is a different model it's just as likely to be fine

If you're unsure then I'd see what voltages your motherboard is reporting, plenty of hardware monitor programs like hwinfo will show them.  Spec says  -5% for the important ones,  3.3V,  5V and  12V.

It'll change depending on load, so use it normally for a few days and see what the min and max values at the end of that are.

If you hit anything like 10.6V on the 12V rail then it's worth considering a replacement. You're unlikely to though.

Thanks i'll look into that app.
If I was to get a more powerful GPU in future i'd consider the RM750X

If there was anything untoward, i'd get some warning signs right ?

BTW this is my PSU....

Where do I find the PSU stats ? Picture included, thanks.

techquest

Absolutely

Venomx999

Cool. So basically
Blue screens, hanging, crashing, loud noises, lagging and errors ?

Well at least I now know which PSU to change to next year then if i upgrade my GPU

When the PSU goes very bad, it might begin to smoke or smell of burning

These would be other main signs

Thanks @techquest

@EndlessWaves
Is this what im looking for ?

techquest

That is what the utility produces. You then have to understand what those sensor stats are telling you. Nothing wrong in that screen shot or probably elsewhere.

Ok a bit of CS GO and the minimum so far is 11.808v

ATX standard specifies 5% tolerance. So 11.4-12.6 is within the limits.

I'll keep an eye on it, thanks.
