Are gigabyte Psus bad?

I'm currently running a 3060+5600x on a gigabyte p550-b power supply. Prior to this i was running 1660 super+3500x on the same power supply in which the gpu went bad after like 3 years of usage. Should i be switching my power supply because i read in a post that gigabyte psus are really bad, which i am confused about because it did run perfectly fine for 3 years.

That one is not part of the exploding units, those would be the PBXXX-GM series (F-Tier PSUs).

However, the one you're using isn't great, either. It's classified as a D-tier.

Only their UD/AP series are good units.

i couldn't really understand the tier list, but if it really is D tier then i think i should replace it. My first choice would be corsair cv-650. is that good enough or got any other recs?
 
Honestly, you don't have to change it right now. The one you have won't blow up and will run your current config just fine. Also, the CV 650 is very average (Tier C). The CM MWE (V2) series is a good starting point (Tier B). Consider upgrading your PSU when you overhaul your GPU, in the future.

Most rated PSU (pretty much all PSU that are not chinese fire hazard and has at least 1 basic rating) has a life expectancy of 5-10 years. So I would say your PSU actually under performed here. You could have tried RMA'ing it since most brands provide at least 5 years of warranty on PSUs. NVM, apparently gigabyte provide only 3 years of warranty on that model which is pretty bad even for gigabyte standards Considering they have had some exploding PSUs in the past and they only provide 3 years of warranty for some models I would say they are bad, period.

Your PC config is quite basic so any bronze/silver tier PSU will work great and it doesn't have to be a PSU from a specific tier list as those are tested on much stricter specifications to pass such tests. So no, you don't need to change your PSU. If you are still worried then make sure you have a surge protector like through an extension board that has one built in or an adapter plug with built in one for extra protection.

In the future if you do upgrade, then get a gold rated PSU and that should be good for the next 10 years.

The model I have does have 5 years warranty, at least that's what they told me when i bought it. Also the psu is still fine, when i said ran fine for 3 years i meant with the old gpu and cpu setup in which the gpu went bad. I did get the PSU RMA'ed once when there was a big fluctuation in my house and it short circuited but that was not the PSU's fault, even the fans and plugs fried when that happened.
 
Let me share my experience for gigabyte PSU.
All of my rigs have gigabyte psu, from 450w bronze to PB850w gold which had issues back for few serial nos....and yes my 2 of those went bad but not exploding like or anything, but after normal use they didn't powered up with load the next day but wud turn on without anything connected so i guess something was shorted but gigabyte replaced them promptly. One the same day and other in 1day. And also have an Aorus 850W one.
The p450 and p550 are the one that i have, been used the longest like 6-7 yrs and that too in a server system that wud run mostly 24*7 and never once had an issue.
I guess that PB series only few serial nos had problems.
And i used those gpus with a 3700x/rx570 and p550 one with 3900x/1660super.
So in my opinion and using experience they are great and had a great service experience also with gigabyte and not just with psu but with gpu also.

Ah makes more sense. I thought you were on your 2nd PSU or something. Okay since only your GPU went bad and nothing else + PSU is fine means it was most definitely GPU' fault. Otherwise your PSU would have gone down with it. o7

Gold, silver, bronze are power efficiency ratings & have nothing to do with psu overall quality. There have been bronze psu from corsair CX series in the past having overall much better quality than some silver/gold rated psu.

They do. Higher rated PSUs are much more likely to use better components than their lower tier counterparts and thus are better overall. I know this isn't the same for all brands and their manufacturers but since we can't test them ourselves (nor do we have the expertise which is why we rely on "PSU tier lists") this is what we base our initial judgement on.

Again, a cheaper & lower tier component might have better efficiency but lesser reliability/life.

If someone is going to use psu tier list like above then mentioning gold. silver, bronze is pointless. If someone is not going to use a list like above then using just gold/silver/bronze might mislead them to buy a poor quality psu. In short, using gold/silver/bronze for psu quality is pointless.

You highlight one model from antec in tier E that happens to be gold rated to base your claim. You do realise they test these PSUs with great scrutiny right? There are outliers everywhere. The same PSU but non-china variant is classified as Tier A BTW so its china doing china thing. Note the warranty period difference, they know.
Look at it from this way, Pretty all models in tier A and tier B are either platinum rated or at least gold with respectable warranty period. Coincidence? I think not.

Also that PSU tier list is rather limited and there are many models which are not available in our market to purchase and many that are not available in their market so they haven't tested them either. So if I can't find a PSU thats on their tier A or B list then I will have to go by effiency rating and the general reviews anyway.

Again, I'm not trying to argue and say you are wrong. As long as you aren't buying a discontinued model (like that one from gigabyte) or a "gold/platinum" rated PSU from chinese no name offbrands with 3 years of warranty you will be okay
 
I don't think they update the PSU tier list that often, if at all. I've had better luck going to the JonnyGuru discord server and asking them directly. A lot of these PSUs are rebranded versions of the same white label designs anyway so they might know about it, even if it is not sold in NA/EU markets.
