Are chinese power supplies reliable?

[Anduin]

Hello guys, I'm planning to run two r9 390x on my pc, but my current psu is Corsair cs650m, which obviously won't be enough. I can get a Thermaltake Smart Pro RGB 850W Bronze for a really good price, but I feel like 850w is cutting it way too close. Which leads to the question - is it okay to buy a chinese power supply, and more specifically this one? I know '90 plus gold' doesn't exist, but it does have 5 star rating (then again only 4 votes..) and the ad says 90% efficiency. I saw that people use those power supplies for mining, but couldn't find useful reviews.. 

I'm like 90% sure I'll go with EVGA or Corsair, because we all know that the power supply is like the most important component and if it's unreliable it can kill not only itself but other components as well. But there's like 10% of my consciousness saying 'Hey, it will be alright! Where do you think those branded ones are made?'..

So would you 'risk' it, or would you buy more expensive power supply from established manufacturers?

850w is enough, but even then i'd just sell both of them and get a 1070ti/1080 with the money instead. One 390x alone eats a ton of power, let alone 2 of them.

I can't follow your logic. Since some power supplies made in China are good, then every power supply made in the entire country is good as well?

Why not think the opposite - since some PSUs made in China are terrible, then all PSUs made in China are terrible?

 

We don't know the voltage regulation, load regulation, ripple, transient response, hold-up time, crossload, build quality, used components and reliability of that linked PSU, and it doesn't even have any safety certifications at all, so no, it's not okay to buy it.

I wouldn't buy it, because it sounds too good to be true, and that means that it probably is.

Don't.

No, seriously, don't do that!
I have two R9-280X (7970GHz) and at the time it wasn't that bad of an idea. But that was something like 5 Years ago or so.

Today things are a bit different and most games just don't work with multiple graphics cards wich means they either don't work or they cause problems/instabilitys...

 

But here we are talking about the devil's circle:

Because nobody had/has SLI/CF; the geme developers don't care about it much.

And because the Game Developers don't care much about SLI/CF, nobody buys them.

 

Wolfenstein the NEw Colossus is one of those Games that don't support two Graphics cards...

WIthout ANy OC on anything it could be enough for testing purposes/short Benchmark runs.

Though I'm not sure about normal operation because I do not have a Hawaii based graphics card and don't plan on gettin one either...

YOu feel wrong.

But I wouldn't get a Bronze unit at that wattage.

I'd get a Platinum one if possible or at least a good quality 80plus Gold one.

Are there any non CHinese made PSU you could buy right now??

Except for the Cooler Master Made in Japan Thingy for 1000 bucks...

 

But, as usual with such broad questions:
Some are good, many are bad. Without knowing what is good, you'd buy a potato or a lemon.

Depends on the 390(x)

There are some with open Power Limit, there are ones without.

At Default they're not that bad, well not worse than other highest end Cards.

But with OC they can be really bad.

 

But I agree with the non SLI/CF Statement. Two Graphics cards are just something you want to play around with, not because it makes sense or is a good idea.

Thank you for the answers Guys!

I decided to pass on that PSU, and most likely pass on the 390s, since as @Herman Mcpootis mentioned 1070ti/1080 will perform better and will cost me just a few bucks extra (which I'll save from electricity bills lol).

@OrionFOTL Yeah probably my logic is a bit broken... As with everything - some of them are good and some - not that much... 

@Stefan Payne You're right! I just wanted to try multi-GPU even though I know it does make zero sense.

IIRC there's some stuff made in Brazil, exclusively for Brazilian markets due to high import taxes.

All desktop PSUs today are made in China.  Labor in Taiwan is too high.  It's getting to the point where labor in China may get too high and some may move to Vietnam, though the Taiwan based PSU manufacturers (CWT, Seasonic, Andyson, Super Flower, etc.) are reluctant because of the language barrier.

 

The Cooler Master Master Watt Maker 1200 MIJ, which is made in Japan.
