Unfortunately no. Discovered it by accident... A guy in another forum was having an issue with his PC and was using this PSU.

BTW, this PSU is being sold for 260 BRL (~84 USD): http://produto.mercadolivre.com.br/M...wer-bivolt-_JM

A bargain for a PSU with 60% efficiency.

yeah,

When you have a %100 import tariff (Brazil)

suddenly it makes sense to build a factory there.

But, like everything...what sounds good on paper doesn't always pan out in the long run.

I have little doubt that the current state of the Brazilian economy (near crisis) is due in no small part to these short sighted economic policies.

PS...a little political, I know, but directly on topic of costs for a "Made in Japan" PSU.

Please note the price of that Goldentec PSU isn't normal. It's just the classic cheating of the vendor. You can buy the same crap rated at 500 W for less the half of that price. We also have all of the best el-cheapo for less than 15 USD.

Also you need to think what type of factory they would implant. If most brands here are just crap and people almost buys crap... I really doubt they would produce anything decent. Maybe they would just turn the things for imported PSUs more hostile (and expensive) with the excuse of protecting the national industry.

Well, this certainly happened. I certainly can't afford (or want) to buy one of these myself, but if I can sell this to someone in some professional workstation build, I will be one happy guy.

Usually we see stripes of solder running across the bottoms of PCB's. Here we see . . . no stripes. The only solder is that holding components to the PCB's. Where do they secrete to current-carrying pathways?

most of the computer power supply industry has build quality good enough to last 10-15 years... 20+ for this one wouldn't shock me
Surprised Cooler Master didn't take the opportunity to one up Seasonic's recently announced 12 year warranty with this model then.

But seriously, we are fans of product like this. We attempted somewhat similar thing back in 2008 with our Zeus ZM1200M where we tried elevating retail PSU build quality with fully automatic robot assembly line.

new OEM and zero statistics on this platform's reliability. On the contrary the existing OEMs have lots of data on their platforms and on almost all cases their new platforms share some (or many) similarities with the old ones so it isn't a completely unknown area.

Once this product is on the market long enough we may see a warranty increase to it. Personally I don't believe in so long warranty periods when it comes to PSUs, because they are high susceptible to external factors.

On topic of non-Chinese/Taiwanese PSU manufacturers, there also used to be a PSU allegedly manufactured in Poland

For as good a build quality and as high a price, I was expecting much better performance and a much longer warranty.

For example...

Voltage regulation *exactly* at 3.300000, 5.000000 & 12.000000 V for the respective rails under ALL load conditions, including crossloads,
Ripple in microvolts or nanovolts, at least tight enough so OklahomaWolf can't measure it,
Efficiency (at 110V) at least 95% on lowest-power standby, 97% when under a low load (like a Pentium G4560T, H110 ITX mobo, simgle 4GB DDR4-2133, 250GB SATA SSD, iGPU, sitting idle on a fresh-installed Linux CLI), flirting with 99.6% from 30-85% load,
S&C spot on,

And anything else I missed, such that OW/JG would have to demote all PSUs that had previously earned 10s overall would be demoted to Hercules / Bestec-caliber gutless wonders.

Oh, and at least a 20 or 25 year warranty, if not longer. And, user upgradeable with newer connectors, reconfigurable power distribution, etc. If the original IBM PC PSU had been designed that way, it'd still be usable today in a system with four 165W Broadwell Xeons, four 250W Maxwell Quadros (no 4-way SLI on Pascal), 12 7200rpm HDDs, etc.
