Hello
I found relatively cheap psu, the model number says sf-550p14p. I can't find any review or even a spec sheet about it. I found it locally but i also found it on ebay

https://www.ebay.com/itm/Super-Flower-SF550P-14P-550W-ATX-Netzteil-550-Watt-31871/123271019287?hash=item1cb3867b17:g:MqYAAOSw4VpcG837

If not this is anybody familiar with Be quiet system power 6 550W(bqt s6-sys-ua-550w).
I found the spec sheet but i can't find any review. I need the psu for:
I7 950
Rx 580 Nitro+

Other options are seasonic s12II 520W(if it has enough watts ?) and also xfx pro core edition 650w but i think it is a bit overkill.
Thanks

The Super Flower unit you ask about belongs to the SF-series and it is both old and discontinued by Super Flower. Only review i found is the same series 400W unit,

That Be Quiet! unit is low quality PSU (made by FSP) and i'd avoid that unit. Also, it's relatively old as well. Review of same series 350W unit,

Seasonic S12II-520, in the other hand is the best group-regulated PSU ever made. And while it also has old platform, just like Be Quiet! and Super Flower units above (released about 9 years ago), S12II series is tried, tested and proven to be reliable. Seasonic (OEM of the S12II series) is still manufacturing and selling S12II series PSUs, even at current date.
My AMD build (full specs with pics in my sig) was powered by S12II-520 PSU for 3 years before i upgraded the PSU and bought Seasonic Focus+ 550 80+ Platinum for it. At one point of time, my trusty S12II-520 even powered my main rig, Skylake, for a period of time. Had 0 issues with the PSU.

Wattage wise, RX 580 is 185W GPU (that's 5W more than GTX 1080). Add the rest of the system to it at about 235W and you're looking 420W as max consumption. OCing your CPU and GPU can put another 100W to the total, making the OC'd PC consume around 520W on max load (100% CPU and GPU). Making the S12II-520 too weak for your OC'd PC. Without CPU/GPU OC, S12II-520 would do fine.

XFX Pro Core edition 650W unit is made by Seasonic and it uses SS-xxxAT platform. This PSU also has old platform (released 8 years ago) but since it has 650W max output, it would suit your PC the best. Build quality wise it's actually better than Seasonic S12II series since it's not group-regulated but instead DC-DC regulated PSU (newer tech),

My Haswell build uses the same Seasonic SS-xxxAT platform PSU but mine is Seasonic M12II-850 EVO. Seasonic also manufactures and sells their M12II EVO series PSUs at current date.

Oh thanks a lot, I didn't even see the notification.
That answered pretty much everything i wanted to ask.
What do you think of used PSU's in general, tbh i was planning on buying used s12 II but I was scared because it was used and it doesn't have some protections.
I was looking also at used corsair TX, found cm v650s and some other high end but used PSU's at an affordable price.
The problem is any new PSU i find that I can afford someone says don't buy it, so it's either shittier psu but new or a better psu but used. If I were to buy an used PSU and it were to fail what are the chances it would burn something else as they are supposed to be high quality units.
Btw how do I put your answer as the solution to the thread ?

When it comes to the PSUs, don't buy used units since you have 0 idea what kind of abuse they've seen and how old they actually are. Also, the older the PSU is, the higher the chance of it dying would be. There are few exceptions where PSU can last far longer than the warranty given to it. I've seen some Seasonic units outlast their warranty.
There's also the issue that almost all PSUs don't have transferable warranty and if the PSU dies at your hands, you're left high and dry. Only exception is Seasonic, who alone, among other PSU OEMs and brands, offers transferable warranty,

So, if you can, try to buy new PSU. But if you don't have funds for new PSU, your best bet would be buying Seasonic PSU. Seasonic hasn't made a bad PSU in their time (they have been in business for over 40 years) and if the PSU has any warranty left, you'll get it with the PSU. E.g S12II series, when purchased after 1st Sept 2012, have 5 years of warranty. If it's older than that, then S12II series have 3 years of warranty.
Though, do note that e.g XFX Pro Core series PSU, despite made by Seasonic, is sold by XFX and XFX doesn't offer transferable warranty.

Reason why Seasonic S12II series doesn't have all the protections is because back in 2010, when S12II was launched, there were no requirements to add all those protections to the PSU that are required today. Those protections that were required back in the day, Seasonic also added to their PSU.

You can give the link of your local store and budget as well, so i can look if there's any good and new PSUs to offer.

Since you created your topic as a Discussion and not as a Question, you can't select Best Answer. Only a mod can change topic designation. (I'll look what i can do.)

Yea I won't buy used then. I searched everything in my country more or less, I found some stuff on sale but it went out before I could order. I can wait until something pops out again. One of those was Seasonic focus plus gold.
Maybe I will buy something over my friend in Germany, I found super flower golden green pro 650W,pure power 11 600w and xfx ts gold 650w around 70 euro.
Idk how this site works yet, if the solution thing doesn't matter to you you don't have to bother with it.
