Cables and Connectors
All of the cables are sleeved in Enermax's standard black mesh with golden threads. As mentioned on the previous page, the cable management works with different jacks on this PSU. The peripheral harnesses utilize a 5-pin port: one pin for 3.3V, 5V, and 12V with the last two for grounding. The connectors are keyed so that they can't be inserted backwards. The PEG connectors for graphics cards come from the 12-pin jacks. The six pins on the left each provide 12V; since each 12-pin connector supports two PEG connections, three 12V cables are routed to each PEG connector. The four PEG jacks and six jacks for peripherals should be more than enough for all but the most insane users.
As the graphic shows, the cables in this unit are not very long. 75cm is the longest distance between power supply and SATA or Molex connectors. This might be okay for many cases, but especially with cases where some hard drives are in the opposite corner from the PSU you will need cables longer than 75cm. The two long PEG connectors is a great idea since the user will be able to route these cables through the case. In addition, there are three more cable harnesses for graphics cards, each with two connectors (6/8-pin transformable). With eight PEG connectors plus features like the 12V rail design, this power supply is truly designed for maximum graphics setups.
The Fan
The fan is a double ball bearing model, frequently used by Enermax. The part number is RL4Z-B1352512LB-3M.

sorry if my english are not good. its not my first language.Aside from that i know what a kilowatt and losses are. I`m not saying they did something wrong. I just wanted some more info on the matter for the pros and cons...

i suppose they're putting all that tech into the very high end market for the same reason as all other techs do; its easy to charge an extra premium (above the normal premium) from those buyers.sooner or later the technology will trickle down into the 'normal' market, where there is more serious volume.
but that's alright, the very high end market just ends up paying our share of the R&D costs that get passed on to them, instead of us.
'bleeding edge' or something they call it? 'bleeding' green :)

The real problem is trying to get all of the necessary parts into a "reasonable" PSU, like something in the 600W or lower range for example. I'd guess they probably put around $100-$150 worth of parts and components into this design, making it fit for the high-end but not much else. If you want to sell 500W PSUs, pricing needs to be below $100 for sure to be competitive, and it's just not all that practical to get there with top-end components (IMO).Keep in mind that most people run PSUs at around 50% load if they want peak efficiency, so this PSU is really ideal for anyone running a ~500W system. GTX 280 SLI with an overclocked quad-core would be just about right I think... if you have enough extra HDDs. That it *can* run anything from 200W to 950W with 85% efficiency (and even beyond if you use 230VAC and want to overload the PSU) is extremely impressive.

"When I first saw the filtering stage, I asked the representatives at Enermax if CWT is the ODM"I consider myself pretty savvy about computer hardware, and I have two engineering degrees (mechanical), but that sentence was meaningless to me.
If you are going to use multiple obscure acronyms in one sentence, please at least include links to what they stand for and some description. It shouldn't take an electrical engineering degree to understand an article on a 'mainstream' computer hardware website.

I don't know about this PSU, but the PSUs in the link below sure look like some Thermaltake units that were made by CWT to me.http://www.enermaxusa.com/catalog/product_info.php...">http://www.enermaxusa.com/catalog/produ...sCsid=e8...

Channel Well Technologies (company..)Original Design Manufacturer (..which was the manufacturer)
Or along those lines.
Note that this is a mainstream enthusiast computer hardware website. =P

When your computer hardware website has a power supply review listed right next to a digital camera review and a Guitar Hero article, that is about as 'mainstream' as it gets.Thanks for the acronym explanation

I will never buy this line of PSUs unless they came out with a 300-350W model.The systems I build use on-board graphics, on-board audio, one HD, one energy efficient CPU and one optical drive. Fully configured, the systems I build for myself only use around 110 watts. Anything over 350W results in wasted electricity.
Look at the minimum power consumption and efficiency at low power draws! That's the most relevant info for me when selecting a PSU.

You can have in USA electrical power on 240V. And the power source will go just as well at 220/230V of Europe as with 240Vstrikeback03 - Thursday, November 6, 2008 - link
Problem would probably be getting the proper cable for the US. Might have to make it yourself.
