I have an old pc which i wanna upgrade to Ryzen 5 2600 cpu, rx 580 8gb gpu, msi b450m mortar max mobo, I wonder what PSU to buy since I want to overclock (as cheap as possible excluding thermaltake rgb having no more stock to buy)
 
Define cheap...? What is your budget for the PSU and where are you located? Also, you should specify your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
OS:

I doubt you could get away with a cheap PSU and maintain an overclock with the limited hardware info you've mentioned above. Heat would be your enemy here.

Oh, thank you again, considering the specs i said above, well bout the ram and storage im not really sureeee, but windows 10 pro will be the os, anddd for overclocking, recommend me a good psu having a low price over its effectiveness, cuz as far as i know other psu's are quite the same having differences in price

You know exactly wrong then. There's no component in a PC with more of a variance in quality than the PSU.
 
And keep in mind, just because it's "in stock" doesn't mean that's what your options are limited to. Sometimes the answer we need, is no, whether we want it or not. And in this case, no, is the answer YOU need.

NO. You should NOT overclock using ANY cheap power supply, regardless of the system or hardware in use. Overclocking is an ENTHUSIAST endeavor, and enthusiasts, or experienced overclockers, know that overclocking on a cheap power supply is asking for trouble not only with the stability or viability of the overclock, but with the safety and potential lifespan of the hardware as well.

NO. You should NOT assume that one 550, 650, 750w unit is the same as any other unit with the same capacity, because that couldn't be further from the truth.

NO. You should NOT simply "settle" for some cheap power supply because it's all you can get your hands on quickly, or any other component for that matter. I realize that sometimes it FEELS like you have to have the hardware NOW, but the reality is, you don't. You don't HAVE to have it NOW. You CAN wait. And if waiting is what you need to do in order to get something that is higher quality but still within your budget, then THAT is what you DO.

You are not alone in this. You are not the only person in the world that is being affected by a limited supply of hardware because of Covid 19 basically shutting down China for four months, both shipping and manufacturing. You are not the only person facing shortages and high costs because of it. If you want to end up with garbage and a POS system that was simply a waste of your money from the start, then settle for cheap parts. Otherwise, do like the rest of us have had to do and make an allowance for the fact that you might have to wait longer than normal to get what you really want or need, and that you might have to pay a little more for it.

Or, you can just buy the cheapest piece of crap you can find for 40 bucks, overclock the heck out of your system and burn your house down. That's an option as well.

In your price range, the two units madmatt recommended are probably your best choices.

You should probably read BOTH of these guides.

A cheap PSU will be made of substandard components. It will not have 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.

If you have a link as to where you might buy, perhaps we can spot a decent psu.
 
The PSU is the most important part in a computer that is often overlooked.

What does overclocking require more of? Power! The answer is power.

And what supplies the power? A PSU.

The cheap power supplies will crack under pressure.

They're not made for discrete graphics cards that need more wattage than the PCI-E port supplies. And certainly not made for overclocking.

When you see a cheapo PSU you should always take the wattage and multiply by 0.4 and that's how much power you can probably safely use. Except in the case of cheap 1000watt+ PSU's. Although I still would never do it.

Cheap power supplies can't deliver the advertised wattage and the ones that can might only last a few seconds.
