Specs:

ryzen 5 2600
asus a320m-k
2x4gb ddr4 2666mhz
a 256gb m.2 ssd
RX 560 2GB
3 x 7200rpm hdd and
2 x 120mm fans.

My old corsair vs450 psu died and needed a stop gap psu and so, I used a 300w oem psu. I did several stress tests for several hours and the system ran fine. Recently though, the pc turns on but can't get into the bios on two different motherboards using the same psu. The fans spin, but nothing happens. I did a lot of troubleshooting and nothing changed so I wonder if the psu has kicked the bucket or something or if it's my ram or cpu ? Thanks.
 
A 300w is simply not enough for that build, that too a OEM unit which is equal to crap. Not sure how you performed the stress tests, but the very fact that you even attempted it is not good for those parts.
2600 is around 125w on load...
560 is around 175w on load...

And we have still not factored in the rest of the parts, which you can add another 50w - 75w easily. Even a top tier PSU cannot give you 100% and yours is not even close. If you want to evaluate properly and mitigate the PSU as a factor then get a good quality working PSU...

For reference, the Corsair VS series is at the very bottom of efficiency and performance.

Okay, so is it possible that a psu can loose efficiency or power output overtime? And for the psu, can I get a high wattage psu like the cooler master master elite 700w 230v? I know it's not 80 plus rated, but I think it will give the system the power it needs also considering that I'm using low powered parts. One last thing, is it possible that the oem psu killed my cpu or ram? Thank you.

Where do you intend to buy a new PSU?

A link to their web site would help us pick a PSU for you, but we have no idea what is available to you, wherever you are. You are probably better off with a high quality 450 watt unit than a 700 watt unit of unknown quality.

Doesn't work that way mate. Quality cannot be compensated by quantity. A low quality unit has a higher probability of failure. That is why they are priced cheaper and comes with less warranty. In this case they might work given enough power but the quality of that power delivery will be inferior with its own repercussions. End of the day its your call. You have all the information to make an informed decision. Goodluck...

I stay in South Africa where decent power supplies (at least to those resident here) are borderline prohibitively expensive. So my price range is R600 to R750 or about $35 to $50. There is literally one bronze psu worthy of note in that price bracket

Is antch a decent brand? This one is also an option->

Post a list of each and every PSU available to you within your budget.

There are relatively few PSU manufacturers, but there are a great many brands. Brand A model 23 and Brand X model 55 may be out of the same factory with the same specifications.

List all possible details of all possible choices and we'll see.

I doubt Antec is a manufacturer. Some of their cases are OK, but I'm not sure about PSUs.

I have no idea if any of these can be used when connected to the electrical grid in South Africa. You may have voltage issues?

Most of the web sites are useless marketing trash, but you might be able to learn something.

I have no personal knowledge of ANY of these power supplies.

I would certainly yield to anyone who does have personal knowledge.

Knowing nothing else, I’d probably lean toward an FSP unit, but only because I know they had a decent reputation 10 or 15 years ago. They can probably turn out trash as well, depending on what specifications the vendor brand wants them to include in the unit.

FSP is the only manufacturer among the list you provided. The rest of those names are just brands that stick their name on a product that a manufacturer turns out. Major manufacturers include HEC, CWT, Enhance, FSP, Seasonic, etc, but most of them do not sell PSUs under their own name. Seasonic and FSP are prominent exceptions.


Antec Atom v550

“atom” yield no hits when searched at antec.com; I don’t know what this is.

Antec uses a variety of manufacturers



Corsair CV450;

https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/Power-Supply-Units-General-Purpose/CV-Series™/p/CP-9020209-NA

40 bucks in the USA direct from Corsair; 80 Plus bronze rating; 3 year warranty



Antech VP500PC;

probably made by CWT; not modular; 2 year warranty; 408 watts max load on 12v rail; no known efficiency rating

https://www.antec.com/product/power/vp500pc



FSP HV Pro 550W; FSP is a manufacturer and does make some OK stuff, but I can’t trace that model

https://www.fspgroupusa.com/ecommerce/retail-products.html





Raidmax XT 500w; Raidmax is mostly made by Andyson,

https://raidmax.com/product_d.php?lang=en&tb=1&id=369

supposedly 648 watts on the 12 volt rail.




Raidmax Vortex 500w Bronze;

https://raidmax.com/product_d.php?lang=en&tb=1&id=812




Cooler master MWE450 230v; most Coolermaster PSUs are made by Enhance or HEC.

https://www.coolermaster.com/catalog/power-supplies/mwe-series/mwe-450/

supposedly rated at 408 watts on the 12 volt rail.
