Hey guys, I want to buy new psu for my little war machine. Specs: i7 3770, 8gb ram 1333mhz, rx 580 8gb. I found Seasonic S12III 550w 80+Bronze for 65e  and Seasonic S12 II 620w 80+Bronze for almost same price. Do you guys know what is difference between these two? Obviously its in these II and III but what that really mean? Should I buy S12 III or S12 II. Also in the future I plan to upgrade to some Ryzen cpu as r5 2600 or r5 3600. Thanks, cheers.

The s12II lacks some protections ( the UVP to be specific ) and the s12III has them afaik.

Either way with this system you won't consume more then 300w at worst 

So go for the s12 triple I 

If you can as well. Consider the cx550.

where do you live, exactly? there are probably much better PSUS at the price of those two available 

It is but human, to err, to buy a PSU, akin to dirt,

but fret not, young Padawan, for we will tell you, 

what will become, of that, which you have earned

If they're the same, get the S12iii. It's group-regulated but still Seasonic so I trust it. Also marginally better protections than the S12ii

Corsair CXM or TXM Gold are better options for only marginally more. If you tell us where you're from, we can look for better PSUs for your budget.

If someone did not use reason to reach their conclusion in the first place, you cannot use reason to convince them otherwise.

Brand isn't quality. 

I can recommend you an N1 

It's cheap and from EVGA. That means it's good right ?

Haha only if i have 2 options that are equally as bad i choose the brand i trust more. Otherwise i agree, go for the product, not the brand!

Seasonic is not EVGA. I can't think of a single time they made a bad psu. Never heard of them catching fire, and I'm honestly astounded at the amount of decent Seasonic units in our list's E-tier.

exactly, the fact that it's seasonic doesn't change the fact that it's a groupreg. You can probably get a CX unit for about the same price, which is, I assure you, much better

@TofuHaroto Seasonic's ECO-430 (rebranded S12ii 430) was probably the most popular PSU in India for a while, basically everyone I know who built a PC had one of them, myself included. They're all still running, 6+ years down the line, with no issues.

The grey CX, yeah, those are great. The lower green CX? Not so sure.

That doesn't mean they can't fuck it up somehow. For example the Asus 5700/5700XT models were terrible. I never heard about GPUs that bad from asus before.

I agree that Seasonic makes good PSU (have/had some of my own). But you should ALWAYS(!) check for options and find a review/get some opionions. That's why we are here :)

Those are from 2013-2016. not sold anymore, no reason to bring those up

It's not group regulated, it's dual mag-amp, afaik.

By that logic, I haven't heard of a single AMD CPU catching fire. Therefore the FX-4300 is not bad.

Where are you buying from? You might be better off getting a lower wattage, higher end PSU.

I can think of a couple that are objectively "bad" for a modern system

s12ii/m12ii x20: Seasonic GB Bronze, uses a decade old platform without 12v uvp, OTP or individual regulation, causing it to easily go out of spec on modern systems due to a high 12v load and a low 5v load

SS-ET/-HT (550/650)/-ES/ECO-BT/ECO-ST/S12 HB/Energy Plus HT/ S12II Bronze ST/ S12II 80+ GB/ S12II Bronze GB/ M12II GM/ M12II Evo GM2 all share these issues because they're based off the same or similar platforms

 

Focus has had shutdown issues on their "V1" models due to the OCP being set too sensitive on transients, with G/SS-RT having this issue reported as well.

 

Prime has had some batches with ticking fans reported due to them using a rather cheap Hong Hua fan (even if this is the same that most of Corsair uses as well, but Corsair generally uses a rather overkill way to drive their semi-passive mode)

 

Seasonic has crap like any other, their name doesn't give them a godly status. does that mean everything from them is crap? no

 

does that mean that they have crap? yes, and  I consider the now decade old S12ii one of them

 

and with that... s12iii is better, but still a double mag amp instead of a dc-dc, which is at low loads worse than it in efficiency, since it needs more load to switch

 I live in Bosnia and Herzegovina and my budget is 60-70e. I know its not much but I can't go over that. Also I don't want to buy used PSU because in Bosnia it's really hard to trust that everything is good with used PSU.  https://www.olx.ba/artikal/38263527/seasonic-s12-iii-550w-80-plusbronze-novo/  this is a link for PSU that I meant to buy

Also seasonic psu calculator says I need 446W psu so buying 500-550w would make sense.

seasonic utilizes outervision for it... I'd honestly call a random number generator more accurate, as it heavily overestimates from the playing around I've done in it. if you were to use any, I'd recommend msi's, bequiet's or ideally calculate it manually here:
