psu COOLER MASTER MWE 550, SEASONIC S12Ii-520 or another PSU?

[derf2ooo]

After deciding my pc build(CPU, GPU, etc...), i checked for PSU´s that would be adequate for my build. I had used a wattage calculator (there´s an attached screenshot of the result, to give you a perspective). I picked a power supply that was less than 60 euros, preferably between 55 euros(including shipping), could be more, could be less. However, after reading the forums and youtube videos, I had more questions than answers about whenever or not i should either get one of the power supplies I planned to get, or to choose another PSU. I live in Madeira Islands, so my options of stores are very low. In fact, I only considered posting here, because i saw a user who helped people outside of North America (which by coincidence the user who wanted help was Portuguese).

Which power supply is good? Do i need to consider a PSU other than these ones mentioned, that can be sent to madeira islands? Should i increase my budget to get a power supply? If yes, how much?

Stores that have physical location in madeira islands, and allow to pick the product in the store without paying shipping fees:
-Worten: www.worten.pt
-Chip7: www.chip7.pt
Stores that can send products to Madeira Islands (which I´m aware of):
-amazon.es (preffered, since they offer free shipping with orders above 30€)
-Globaldata: www.globaldata.com(last resord, since they charge a shipping fee) 
-pcdiga: www.pcdiga.com(last resord, since they charge a shipping fee) 
PSU´s I considered (both of them belong to the stores with physical locations:

I have multiple systems with the seasonic S12 520W and had 0 issues.

I even ran one with 2 rx 570's, no issues at all. 

You can't go wrong with the seasonic one.

Thank your for the info.

S12II is group regulated which may not suitable for modern systems. Guess @Stefan Payne can explain more on this.

Well, you can go wrong with the Seasonic one. It's an 8 year old, bottom of the barrel design that shouldn't be used in modern computers anymore, and lacks some important protections.

 

Your setup with the Ryzen and GTX1060 will consume around 200W under load. Corsair CX450M https://www.chip7.pt/fontes-alimentacao/15645-corsair-fonte-builder-series-cx-v2-450-watt-semi-modular-80-bronce-atx-cp-9020101-eu-CP-9020101-E.html is a much better power supply and will work good. If you want to have something higher quality, get TX550M: https://www.chip7.pt/fontes-alimentacao/25330-enthusiast-series-tx550-watt-modular-power-supply-CP-9020133-E.html

I understand. Thank you for explaining your point of view and your suggestion.

I still have questions about the MWE. I mean it´s made by cooler master, a reputable brand that is know to make good power supplies (linus even showed a 1200w PSU from coolermaster in the threadripper build iirc).

Cooler Master is NOT the maker of their PSUs, but simply rebadge units produced by OEMs you havent heard of. Their history on PSU is complicated either, some PSUs are good while some are disasters. The same goes to all brands, so dont be fooled by fame. Actually, Seasonic is the few brands out there that make PSUs themselves, but selling outdated units are a problem for it as well. No one's perfect.

 

Tier 3 or above is good while tier 4 is good for cheap systems (like 10 year old Core 2 Duos)

 

Dont know what the MWE's made of yet, so better not risk it.

I see. It would be nice to know where the MWE would be made off. Thanks for the info.

MWE 550W is made by HEC, and it uses a double forward, group regulated topology - the same outdated principle as the Seasonic S12II, which doesn't respond well to load from modern PCs. The MWE line is tricky, because only the 600W and 650W models use DC-DC converters, while 550W and everything below uses group regulation.

You can't choose computer components based on brand: MSI GTX1080 GaminX is a fast card, but that doesn't mean MSI GT1030 is fast too. Cooler Master MasterWatt Maker MIJ 1200 is an extremely well-built power supply, but Cooler Master MWE 550W uses the cheapest design possible.

 

Between Corsair CX450M and Corsair TX550M there's also Corsair CX550: https://www.chip7.pt/fontes-alimentacao/21087-corsair-fonte-cx550-550-watt-80-bronce-cp-9020121-eu-CP-9020121-E.html

It uses an upgraded design than CX450M (half bridge LLC resonant with DC-DC converters), but it doesn't have modular cables. The warranty for the CXes is 5 years, while for TX it's 7 years and it will last much longer.

It does not matter who builds it.

It matters what the product manager wants and how much they are willing to pay...

No, they don't just rebrand PSU, they let the manufacturer do some changes for them.

And if you want to, you can ask them for a new layout - like be quiet did with the L8.

 

The normal Master Watt is very different to the Cougar LX or be quiet System Power 9 - all three use a similar basis...

If you do it yourself or not does not matter that much.

And there are a couple of other brands that do stuff themselves - some of them are good, some of them are not...

Like FSP, HEC/Cougar (except the GX-S series), Huntkey...

And in some areas Acbel High Power, Delta, don't know if CWT still does something in the Consumer are or just does contract manufacturing.

 

Oh and there are also some pretty shitty companys that do manufacture stuff they sell themselves but lets not talk about it. Really not worth it...

 

You see there are a couple of manufacturers that still do consumer stuff but that's not a priority for many or even most of them.

 

 

If you are a good contract manufacturer, you do as you are told/asked by the contractee...

 

Because if you do not do it yourself you can go to everyone you want to and make a really neat lineup and most of the R&D is already done by the manufacturer, you only have to pay a rather small fee for some rather "minor" modifications like a case...

My decision will be choosing the corsair cx450m power supply. I've seen a build with the same cpu and gpu that used a 450w power supply. Thank you all for the really helpful advices and suggestions.
