Super Flower Amazon 650W Power Supply

Temperatures, Fan Speed, and Acoustics
Both heatsinks remain very cool relative to what we normally see. During testing they stay under 50°C and only surpass that temperature when we exceed the maximum 650W power rating. The heatsink and exhaust temperatures are very close, which shows that the power supply is doing a good job of getting rid of excess heat. The Super Flower 650W achieves one of the best temperature results we've seen to date, likely helped by the 140mm fan.
The fan speed remains at its minimum 600 RPM up until 80% load. With a large fan size and good heatsinks, temperatures are low enough that the fan simply doesn't need to spin any faster. At maximum load and with a warmer ambient temperature the fan begins turning faster, but it still doesn't reach very high RPMs. A quick calculation of fan area indicates the 140mm fan should move at least 36% more air than a 120mm fan, so even though the fan speed is much slower than what we normally see it should be sufficient.
A major advantage of having a large fan spinning at lower RPMs is reduced noise levels, which we see in the above graph. In fact, outside of fanless power supplies, this is the quietest power supply we have ever heard -- or not heard in this case. It stays at an incredible 18dB(A) up to 550W, at which point additional loads increase the noise level by 1dB(A). The fan makes no noise that we could detect, and there wasn't any ticking (something we've noticed with some other low RPM fans). Whatever else we might say, the 140mm fan with ceramic bearings certainly impresses.

Did I miss something or did the reviewer not tell us how much this thing costs and where you can get it?Christoph Katzer - Wednesday, October 22, 2008 - link
"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."In the time you wrote that totally unnecessary post you could have found it on the last page.

Obviously I missed it, which is why I said "Did I miss something"And for your information dickwad, I looked on all the pages, just missed that last sentence. It is possible. I goofed. Don't be such a little bitch about it.
I thought pricing info would be on the first page where it says "Prices"... silly me, I thought that would be prices for this product reviewed, when in fact it's just revenue generating advertisements ( which I DID click on because I did THINK those were the prices for this product... your welcome. Send those few dollars to the JWAP Foundation. ( Journalists Who Aren't Pussies )
Let me rescend my apology. I read the article. Right below where it says
Date: October 16th, 2008
Topic: Cases/Cooling/PSUs
Manufacturer: Super Flower Inc.
Author: Christoph Katzer
It then says:
Prices
- TECHONWEB $122.91
- HP Small/Medium Business $29.89
- Dell $99.99
- Dell SMB $39.99
- HP Small/Medium Business $40.35
- Dell $99.99
Silly me, Im thinking this is a great deal! It doesnt say anywhere on this first page that this is a "not yet shipping" product.
Why would you? Its obvious that the advertisements are strategically placed to generate clicks through trickery.

"Several years back their units were a lot more common and you could find them in online shops around the globe, but their presence has been fading. However, we have reviewed a few other brands that were built by Super Flower."For those whose memory isn't all that great, and who are too lazy to go back through the previous P/S reviews, could you remind us which other power supplies that have been reviewed were built by SuperFlower?

Kingwin for example: http://www.anandtech.com/casecoolingpsus/showdoc.a...">http://www.anandtech.com/casecoolingpsus/showdoc.a...You can recognize other SuperFlowers by their distinctive heatsink design and the cable management with the special connectors. Some Topower builds have the same cm-connectors though, since it's actually their patent but until now only Tagan used them (afaik).

Only thing I see good about this PSU is the fan and resulting noise (lack of) from it.Voltages are too far out of alignment, and the ripple isn't great.
symbul - Monday, October 20, 2008 - link
You are KIDDING about the ripple, right? I mean, a max 7.87 mV (if accurate in the retail version) is a great spec. Even the 650W Antec Signature (which is the best 650W out there) can't do that...Spivonious - Thursday, October 16, 2008 - link
That 12V graph looks pretty shaky. What does that mean in terms of the voltage/power delivered?Spacecomber - Thursday, October 16, 2008 - link
I was looking through the comments to see if anyone had any insight on how to read that graph, too, since it looked to me like what I would assume to be rather "rippled", especially at full power.On another topic, with no production units available and therefore no firm pricing, this kind of preview is interesting, but it is not as helpful as a review of something that I can actually buy and therefore determine an actual value for. Certainly, we haven't run out of available power supplies to review at this point, have we?

below 8mV of ripple...is extremely low. So low I am not sure I believe it.
