I think six SATA power connectors should be plenty for most users. Who has more than four HDD/SSDs anyway? But, the connectors should then be divided in 2+4 rather than 3+3 on the cables.

Then the power distribution is a little strange. All 12V lines are nominally rated for up to 17A, corresponding to 204W, but one 6-pin and one 8-pin PCIe connector are supposed to deliver up to 225W (18.75A) together.

In the tests you pull up to 31A off 12V1, which is a full 14A more than specified. That doesn't say much about the OCP, does it (other than that it isn't very tight)?

Cheers
Olle

Please revise your review to reflect that the capacitors are NOT Japanese. Toshin Kogyo are rebranded OST capacitors and do not manufacture their own products. So they are in essence a Japanese distributor of Taiwanese capacitors.

OST capacitors do poorly in motherboards, but fare so so in power supplies. If you want evidence, I can show you a photograph of a failed Toshin Kogyo capacitor in an Asus P5B motherboard.

My friend, thanks for this information, I didn't know that. Do you have any link that you could post to back this information up?

Updated 11/22/2010: PowerColor sent me their 80 Plus report. Ecos Consulting explained that they only post the report on their website after the manufacturer approves the publication. Therefore, I fixed the review to add that this unit really has the 80 Plus Bronze certification. I also updated the review to add that the presence of four video card power connectors instead of six may be a limitation for users looking for a power supply in the 850 W range

i second this information. its true. "tk" are mediocre capacitors. and sort of cheating and borderline lying "jap caps"

Thanks for the explanation and link, this was highly appreciated. I am going to revise not only this review, but all the reviews that carry this information right now.

As for ECS vs. PC-Chips, the story is a little bit different, because they were (when Dinossaurs were still around) two distinct companies, different owners. Then PC-Chips bought ECS (and not the other way around, as many people think, because Elitegroup Computer Systems started to be the company legal name) and they kept both brands. Right now PC-Chips brand is no longer used, only ECS.

Thank you guys,
Gabriel.
