500W to 550W: 12 Power Supplies Compared

Arctic Cooling Fusion 550R - Overview
Arctic Cooling is famous for their CPU coolers, which were very popular in the late 90s and early 2000s. With prices of around $20-$25 and very good performance, they sold a ton of these coolers. Eventually, Arctic Cooling started selling cases with power supplies made by Seasonic. That leads into today's review, with Arctic Cooling now selling power supplies under their own brand -- a potentially lucrative proposition, provided you have a product that can stand out from the competition.
The Fusion 550 is the first power supply from Arctic Cooling, and given their previous use of Seasonic power supplies in their cases, it should come as no surprise that the Fusion is manufactured by Seasonic. The difference is that Arctic Cooling uses their own fans, which are supposed to be nearly silent while still providing good performance. Arctic Cooling mounts one of these fans on the front of the PSU, with the fan actually located outside of the casing. This fan will funnel air into the PSU, and possibly do so with less acoustic noise than the competition.
In a case of interesting marketing, don't be fooled by the Eco 80 emblem on the top of the power supply. This sticker has nothing to do with the 80 Plus certification from 80Plus.org, despite some striking similarities. We will see later that the Fusion 550 does manage to achieve 80% or higher efficiency, but since this power supply did only come with 230VAC it was not able to be certified by the 80 Plus programme. Arctic Cooling does however have a multiple input version now that comes with the real certification.
When we open the casing, we find a standard Seasonic layout. Right in front of the fan is a large heatsink that will get plenty of airflow for cooling. A plastic shroud is also present to help channel airflow into the optimal locations, further helping control heat. A heatsink on the side won't get much airflow, but since there aren't many components attached to that heatsink it shouldn't be a problem. A Nippon Chemi-Con capacitor fills the primary role, with Ostor capacitors in the secondary. Ostor might be one of the cheaper capacitor options, but we didn't encounter any problems with these components.

Any good PSU review need to include reliability test when two PSu are joined by soldiering the green cable (and one black).It allows to use two cheap units as one more powerful one, saving lots of money for value overclockers. But is not ever safe. Not all power supplies are reliable when joined this way.
If the two PSU is bad, there are a risk of getting a burned (and costly) video card, or BSOD by electric instability.
But value overclockers take risks to save money, and spent scarce money in the right components.
That is the reason for which that hard to find and very valuable info is so useful.
Please, consider it next time you do a PSU review.

I'd like to see a few tests done that would show the variation between identical units. These powersupply builders rely on other manufacturers for the components, so the chances for a bad component to make it into a unit is a lot higher than for some other computer equipment.7Enigma - Friday, February 20, 2009 - link
That is a very good point. And it wouldn't be too difficult in terms of additional testing since only the major tests (ripple, voltage flux, etc.) would need to be tested.Even an N=2 would be a good quality check.

congrats for including Arctic Cooling and Akasa units. will ready more carefully later. cheers.7Enigma - Friday, February 20, 2009 - link
I'm really upset with the Tuniq's poor showing. I built a system last month using the Tuniq after recommendation by Mr. Katzer in the comments section and had thought it would have performed much better. I ended up only paying $40 (if the $40 rebate actually comes in) which is about as low as you can get for a 550psu, but I would not have chosen it if this review had been available.Really disappointed.

It seems that PSU reviews dominate the reviews here at AT lately. Where did all the memory and CPU shootouts go? What about comparing panel sizes and reviewing them?I don't want to take anything anything away from this PSU review, it was excellent. Just give us more review variety!

DDR3 Roundup - 3/3 (nine sets, 1066~2000)DDR2 Roundup - 3/10 (eleven sets, 800~1150)
Interspersed each week for the next month will be various motherboards in the under $150 price range, budget CPUs, storage (external, NAS, internal HDD/SSD), and even some GPU action showing what you get for under a $100 compared to integrated graphics. We just went through a major overhaul of our base test suites, start rolling out the new stuff next week.

What are you talking about? There's plenty of that kind of coverage...http://www.anandtech.com/guides/showdoc.aspx?i=347...">Holiday Memory Guide - several choice DDR2 and DDR3 modules are listed with OC results.
http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">Phenom review, with lots of benchmarks comparing almost every current AMD and Intel CPU.
http://www.anandtech.com/displays/showdoc.aspx?i=3...">24" LCD Roundup is a little outdated, but monitor models don't change over as often as CPUs do.

Christoph,This is easily the best presentation of material I've ever seen on Anandtech. Furthermore, it's a survey of mainstream components which is probably what 95% of your readership is going to buy. Those two things easily make this the best article I've ever seen on Anandtech.
As someone who does technical presentations all the time, I know how difficult it is to condense large amounts of data into easily understandable formats. You really did a fantastic job. Thank you, and I look forward to more articles.

Agreed, excellent article. Now give XClio some love!
