Conclusion
From what we saw during testing, the Super Flower Amazon PSU appears to be a very good product. Of course, since this looks like a preproduction unit we can't say for sure how it will compare with actual retail models made on the standard factory lines. Super Flower says the unit we received should be representative of stock units, and if so that's great; we will make sure to get our hands on a retail unit for comparison once they begin shipping.

In terms of feature set, there's nothing truly remarkable with the Amazon series. It's a typical power supply with no funny gimmicks; the only really noteworthy feature is the 140mm fan. It provides very good voltage distribution, good efficiency, and very silent operation. The build quality is very good as well, even though we don't like to see large amounts of glue all over the place. The length of the housing might be a little long for a 650W power supply, but that's because Super Flower uses the same topology for all of the power supplies in this series. They selected high-quality components, and the result is a very good power supply. The number of connectors is good for a 650W unit, allowing users to power up to two of the most powerful GPUs currently on the market. Cable lengths are also decent, with 50cm ATX connectors and PEG connectors at 50cm and 65cm.
The overall performance is very good, surpassing much of the competition that has been around for a while. Voltage regulation was good on the six important 12V rails. The 3.3V provides a constant high voltage of up to 3.47V while the 5V rail is almost the opposite with somewhat low results under higher loads. The efficiency reaches up to 87% with 230VAC and up to 85% with 120VAC.
The temperatures inside of the power supply were very low, reaching only 50°C with normal ambient room temperature. The fan spins at a very sedate 600RPM most of the time, and only starts turning faster at more than 80% load. The temperature does begin to rise at higher loads, and it would have been nice if Super Flower allowed the fan to spin a bit faster at maximum load -- obviously there's still plenty of room left in terms of noise output. As it stands, the Amazon 650W only puts out an exceptional 18dB(A) at up to 550W, making this the quietest actively cooled power supply we have seen to date. If you are like most users and you have a PC that never requires more than 500W, you will never hear this PSU.
The only real question we have is pricing. We will have to wait until Super Flower begins shipping these units to get a price quote.

I think it's actually interesting what companies can do. It might not be helpful to find a new PSU for your setup, I know, at least not for now. It's showing however what the companies are capable of.InvertMe - Thursday, October 16, 2008 - link
"Super Flower says that we did not the unit we received should be representative of stock units,"Just letting you know. :)

"(Ed: The English grammar on the packaging could also use some work.)"Other then the slogan ("Always Accompany With You") I didn't see anything that odd. The Cooler Master Centurion 5 box, for example, is much more interesting.
Looked like there were some burn marks or something like that on parts of the heatsinks? Is that a varnish spray or something?

Regarding grammar, I was thinking more of the packaging, not the PSU label. You can see what I mean in this image:http://images.anandtech.com/galleries/248/08.jpg">http://images.anandtech.com/galleries/248/08.jpg
Is it terrible? No, but there are lots of little things. "Support Intel Core 2..." instead of "Supports". "More than 2000 times ON/OFF test." "PCI-E 6pin and 8(6+2)pin Connector Satisfy High-end Graphic Card Requirement." (...connectors support high-end graphics cards" would be better.) Just a guess, but I'm sure their manual has some interesting wording as well. Never mind the company name of Super Flower, which sounds like something from the 60s. :-)

Could also be the name of a Chinese take-out place, they tend to follow a form like that.Sure, the label isn't great, but compared to some of the boxes and manuals I have seen before it is quite clear. As you said, their manual might prove more interesting.
