Since i'm upgrading my 750 Ti to RX 570 i need to replace my PSU because my old Chinese one didn't even have PCI-E connectors and didn't mention how much power it have on it's rail, it served me well for a good year and 10 month, anyway 2 days ago i went to the local stores near me to buy a new one, i ended up buying the Cooler Master MWE 550 80+ White for $48, that's the best i could get with my budget, i tried to stay away of brands like GameMax, Huntkey, Aerocool etc , did i make a good decision or what ? i could've bought the Thermaltake Litepower 450 for $52 or the Cooler Master MWE 450 80+ Bronze for $46.

and btw it'll be powering :
Xeon E3-1245 V2
2x DDR3 8 GB 1600 MHz Memory
Asus ROG Strix RX 570 4GB (Planning to OC)

I've had decent luck with coolermaster PSU's over the years. That said, I learned a long time ago not to skimp on the power supply. My Antec smartpower 2.0 500w died and took my record overclock holding Athlon X2 3600+ with it. I've stuck with FSP, EVGA, and Corsair ever since.
 
I've looked at this PSU and couldn't find much bad about it. Not a top tier but certainly at the same or better level than Corsair CX. And well priced too.

Its not modular, but very little is at this price point.
 
Can you explain what do you mean by OEM design ? and i couldn't find a review for it on jonnyGURU website

Basically who made the inside 'important' part of the PSU,the brand name you see on the PSU is not always the same as the manufacturer.

I have the Cooler Master MWE 650 Gold and this apparently is CM's own design.

So far I have no issues with it other than the slight idle coil whine but thats just bad luck on my part,can happen to any PSU. :/

It should be alright,my previous PSU was also a low-entry level Thermaltake 450W and I had to replace it when I bought my RX 570 cause under gaming load the PSU fan was annoyingly loud.
 
The OEM should be HEC. HEC are a midrange PSU manufacturer. While they might not be the best, they aren't the worst either.

They make a lot of the generic grey PSUs that folks like Dell might use in their builds
 
I think its a preety good PSU at that price point. I have a MWE 500w in my currect pc with a RX 580 and have no complaints on it, silent and no coil whine.

Original Equipment Manufacturer. Basically, what's inside before they put the brand sticker on it.

This is a super useful site

Note that the same OEMs also do use different platforms, but on general things like overall quality, quality of components and soldering jobs there is certainly some idea of reliability. Some good ones;
Seasonic, Delta, SuperFlower, CWT (if high end)... with these brands you really do get what you pay for, but the bottom end quality is also in the 'good enough' zone.

Yeah I actually messed up trying to do this. Seasonic dont sell any PSU's locally so I try go for the Antec units made by Seasonic. When I bought my Antec Neo Eco the advertised specs listed a single 12V rail but the PSU arrived with two 12V rails instead. Turns out it was a blessing in disguise the single rail unit would have been a CWT but mine is at least a Delta made unit.

I usually use this link:

Edit: I also have a Thermaltake Litepower 450W (FSP) PSU for 8-10 years now. It's supposed to be a relatively bad quality PSU but works fine In practice. Used only with old components in case it ruins them.

You'd be surprised how many Brands use near identical designs, and the only differences being internal components. Seasonic makes a whole range of quality from the 'dont try this at home' to 'marry me and have my kids'. The most important rule to follow here is "You get what you pay for", meaning, dont skimp on the PSU if you dont have to.

The thing about Seasonic that has made them famous is they skipped the "don't try this at home" category.

Pretty much all their stuff will deliver it's nameplate wattage. None of it will blow up short of a defective unit. That didn't used to be so commonplace.

That may be true now, but they didnt skip it, they grew out of it.

Nope. Not Seasonic...
Here is a bubble, dont drop it. :p

If that is true (I dont recall this), they've grown out of it at least a decade and some change ago. Really one of a very few brands that is good or great across their whole line (aka zero 'dont try this at gome models). Your post says "makes", as in present tense, and that isn't remotely true at present or in the recent past. If you can find some reviews of consumer psus from seasonic being potatos, link them up. :)

As a brand, I can agree, but as a manufacturer of other brands...

Your posts went from 'currently makes' (duds) to they 'used to make' (duds) to 'not seasonic labeled' are (duds)???? o_O

I'm going back to the bourbon and the Lakers game. :)

Merry Christmas!

You should post what you mean then.. you used the present tense.

Ping me when you can prove Seasonic labeled psus were junk. Mmkay? I could stand to learn a thing or two.

Cheers from Mitchels. ;)
 
Unit should be fine.

Seasonic is usually a safe bet.
Lets say i dont remember anytime in the past 16y (i started to look at better stuff) where i wouldn't use any SS unit (gold and up).
They do sometimes miss the mark here and there were they could have done (minor) stuff a bit better,
but usually reviews only list price as a "con".

Do see the EVGA G3/P3 series being a tick better in +100$ range (vs prime/focus) and at least level with corsair AX.
