How is it possible for a PSU that is rated at 150V-240 input voltage to pass 80plus certification?

The rating is more than likely wrong. I'd say that the power supply probably works OK at 115V.

That's possible. Another possibility is that the test sample indeed can work properly at 110V despite what the label says. However, Ocing Tech do some twists to the retail units so that the retail units can only work at 155V-240V range. As a result, they managed to have a geunine 80plus badage on their 155V-240V units. That could be a smart move since they only sale those PSUs in China. Nobody here cares if it can works at 110V.

Possible, but it's still kind of dishonest for a company to send a different unit for testing to what they sell to the public, but that doesn't really surprise me for a company I don't know much about.

Hey, do you have any idea how much that model would cost in China? It would give us an idea of just how trustworthy the company really is.

Hmm. The retail version has a different model name compired to the test sample even though they share the same Chinese name: A4 modular edition.

The model name of the retail version: TU500-12
The model name of the test sample: TU530W

Apart from the model name, they look identical.

MSRP for the TU500-12 is RMB330 (roughly $53)

Well, that's expensive enough to be half decent, so it's entirely possible that it is 80plus compliant.
