Default Corsair VS series PSU quality?

I don't have any knowledge about electrical engineering but is there any way to load test a PSU that accepts 220-240V input voltage in a country that has 115V.
The problem is that the Corsair VS series accepts 220-240V and hence there are no reviews on it since all reviewers are mostly Americans which have 115V. AFAIK VS series is only sold in India and China. And no one properly load tests and review it in India and China.
Corsair claims 85% efficiency(at 230V, 50% load) but isn't 80 Plus certified due to the same reason as above?
Spec-wise it seems good like Corsair VS550 has 42A@+12V rail.
But i have heard it has low quality CapXon capacitors and a little bad voltage regulation.
I am highly suspicious since it is selling for cheap in my country. Its the most popular psu series on the country's most popular tech buying site.
Corsair is a highly trusted brand but is it fooling customers in India and China?
I just want to know how good or bad it is at its price point.

Also where are 80 Plus certification labs located? Are all in America? If in US then even a great 220V PSU will never get certified then?

Hi, the 80 Plus certification is an initiative of an American organization and they only test power supplies at 115 V, except power supplies for data centers, which are tested at 230 V since data centers use this voltage to save on the electricity bill.

Let's wait until our good user c.hegge sees this message; he lives in Australia (230 V) and he tests power supplies there.

Thanks for the info. I'll wait.

Here is some pricing info if needed as of today

Corsair VS350 INR 1870 (30.46 USD)
Corsair VS450 CP-9020049 INR 2359 (38.42 USD)
Corsair VS550 INR 3146 (51.24 USD)
Corsair VS650 INR 4157 (67.71 USD)

We have higher prices in India due to customs,duties,taxes,etc,etc.
So here are prices of some good psu's for comparison

Corsair CX430 CMPSU-430CXV2 INR 2938 (47.85 USD)
SEASONIC S12II 520 BRONZE SS-520GB INR 4500 (73.29 USD)

I have reviewed a VS450. (see http://hardwareinsights.com/wp/corsair-vs450-review/)

The performance was acceptable (although not spectacular), but the secondary side caps do worry me a bit. Knowing CapXon, they will probably just make it through the 3 year warranty period, and die shortly after.

So it does pass the test, and can be overloaded.
U have written Test 1 (70.64W Load – Cold) - What does the 'Cold' mean?

So i guess the Corsair VS450 CP-9020049 at 38.42 USD is better than Corsair CX430 CMPSU-430CXV2 at 47.85 USD
and Corsair VS550 at 51.24 USD is better than SEASONIC S12II 520 BRONZE SS-520GB at 73.29 USD
Am i correct or wrong? I am comparing (performance & quality)/price

Cold just means that the intake air was barely warmer than room temperature. I have stopped doing that since I got a proper 5 position temperature sensor.

I think the S12II 520 is absolutely worth the extra $20 over the VS550 due to its far superior build quality and efficiency.

As far as the CX or VS is concerned, The CX is more efficient, but the build quality isn't much better, so you might just be better off with the VS.

Thanks for the advice.

I just noticed this :
SeasonicUSA.com lists S12II 520 BRONZE as having 5 yrs warranty
http://www.seasonicusa.com/S12II-Bronze.htm
Seasonic.com lists S12II 520 BRONZE as having 3 yrs warranty
http://www.seasonic.com/pdf/datashee...I%20Bronze.pdf
What's this?

I've noticed that here too. I'm not sure why that is. I guess 3 years is probably a safer assumption for other countries.

Thumbs up

Would recommend the Seasonic clearly over the Corsair VS. Used in the past Seasaonic S12-II rebadges from Antec and XFX, very reliable PSUs

But if you donīt need this wattage take a look at the Seasonic G-series or Enermax Triathlor 385W or higher (the 300W is a CWT-build)

I already own the Seasonic S12 II Bronze 520W. I bought it 1.5 years ago.
I only asked this question because the Corsair VS series is the most popular psu series in my country right now
