At Icrontic we respect the right of software and hardware manufacturers to comment on our pieces to ensure that their products are being presented in a fair and accurate manner. Should a manufacturer or vendor choose to contact us regarding our work, we promise a verbatim reprint of their comments.

With this principle in mind, we received an email shortly after publication from Corsair Senior Technical Marketing Specialist Robert Pearce. His communication has been reprinted exactly as received:

I finally got a chance to read through the article and have a couple of concerns.

The ripple he’s talking about is 40mV on the +12V, which is literally 1/3 the spec of 120mV that’s allowed.

He’s also concerned about a drop on the +12V rail output from 12.00V to 11.8V, which is less than 2%. The ATX spec is +/-5%.

In any other review these specs are phenomenal…

10 Nov 2008 ~ 2:19am Leonardo Although one anecdotal account certainly doesn't make a trend, I can tell that I am completely satisfied with this PSU. I have the same model, which I've been running for about a year and a half. (I don't know what, if any differences there are with the new ones.) The system it runs has a Q6600 with a 1.2GHz overclock and one each 8800GT and 9800GT, both overclocked. Both video cards and the CPU run 24/7 at nearly 100% load, Folding@Home, without a hiccup whatsoever. It's my main home computer so I frequently have multiple browser windows open simultaneously with the Folding in addition to MS Office and Open Office applications. At least in my experience, this is one of the best hardware components I've ever put in a computer.
10 Nov 2008 ~ 3:21am Komete I also have this power supply. I've been very satisfied with it. One thing that does concern me is its modular cabling. I once read an interview where someone at OCZ was being interviewed. I don't remember the details, but I remember him giving a compelling argument against modular cabling. It was something to do with electrical resistance at every split juncture.

I think this review i spot on.This power supply is good for the average overclocker like myself. It is more than enough for those who don't overclock. But for those looking for the pinnacle of performance, a higher end non-module power supply should be sought after.

One thing I wonder about is if it better to use up every connection on on a branch or is it better to only use one plug on a branch per device if possible. If anyone has an answer to that I'd appreciate it if that could respond.
10 Nov 2008 ~ 8:52am bullzisnipr I think I'll add this and another 4870 to my arsenal.

10 Nov 2008 ~ 10:51am Thrax Dras kindly provided lots great of technical data for this article, but I did all of the writing. I'm trying to fix that 1em shite.
