Question Should I replace my generic psu for an 80 plus

I was planning on buying an xfx rx 580 but looking at my rig I'm feeling skeptical it won't. It's a generic cvs p4-700 that I bought from Facebook marketplace that came with a motherboard that was around php500-ish(Philippines) so I had to ask if it might still work or better off buying a new one that is capable of working with less problems
 
Of note, simply being called "80 plus" really doesn't reflect on a level of quality being high. You should consider the build quality of the specific unit, check reviews, and really just investigate the stated voltages on the label to see if they are pulling some tricky math to achieve stated power level. 80 Plus has a range of certifications from Bronze, Silver, Gold, Platinum. So far as I am aware (and stand to be corrected) the "80 Plus White" (sometimes stated with or without the white aspect) isn't a real standard for their certification.

Of note that even units rated on the real scale aren't always necessarily good units just because they meet that standard.

This doesn't mean you have to rush out and buy the most expensive unit you can find, but typically want to look for things like long(er) warranty period where the manufacturer is standing behind the product they offer. Stick to well-known brands where possible, and that may be regional. Using an inexpensive power supply can make sense with certain builds and you really have to weigh that against the possibility that it could damage other components. In essence a situation where saving money one place could cost you money elsewhere.
 
Yes, the PSU in question is a fake 700W with cheap, junk parts, and a design only suitable for office PCs before Pentium 4 CPUs.

You need a quality midrange PSU or better to bother with an RX 580. And it's going to cost a lot more than garbage like this, unfortunately. Just to illustrate, I can find this listed PSU for about ₱595 or about $10 USD. Looking at Shopee, you don't start to see good midrange PSUs until the ₱5000-₱6000 range.


Nothing below Tier B ought to be used with a GPU that requires supplementary power except in an emergency (and gaming is not an emergency). This is the cost that goes with having a decent GPU. Sure, it's an old GPU now, but the costs associated with it still remain.

What are the rest of your parts?

That psu looks to be a cheap unit.
Do not buy it.
A cheap PSU will be made of substandard components. It may not have all safety and overload protections.
The danger is if it fails under load, it can destroy anything it is connected to.
It will deliver advertised power only at room temperatures, not at higher temperatures found when installed in a case.
The wattage will be delivered on the 3 and 5v rails, not on the 12v rails where modern parts
like the CPU and Graphics cards need it. What power is delivered may fluctuate and cause instability;
issues that are hard to diagnose.
The fan will need to spin up higher to cool it, making it noisy.
A cheap PSU can become very expensive.

Do not buy one.

How can you tell about psu quality?
Barring reading a review, look at the warranty.
A psu with a 7 year warranty will usually be very good.
Do not buy anything less than a 5 year warranty.
