Comon' what? Try reading your own PSU guide and read between the lines of what I said. Obviously not all PSUs' are manufactured to the same standards, use quality caps, have the beefiest heatsinks, or tight power regulation.
Yes, we should all do our homework and get supplies that are high quality, but I don't see how this is relevant to the issue at hand.
You're kidding, right? Do you really not understand that quality is connected to everything? For example, high-quality capacitors mean more consistent/reliable power output and tighter voltage regulation. Bigger, beefier heatsinks handle heat dissapation better than smaller heatsinks. Better heat dissapation means cooler running components, which leads to longer component life and higher reliability as well as better efficiency.
All I see in that article is something I already knew and have known for years - PSU wattage claims and ratings often don't mean sh1t. Quality of manufacture does.
Then tell me what quality of manufacture has to do with a supply being able to handle a system with 2 X1900XTs in it.
You really don't get it, do you Howard? What do you think my "Gee, I wonder..." comment was about?
Gee, I wonder why that PC P&C 510 SLI passed all the tests when its only rated at 510W when some PSU' of much greater claimed wattage failed some tests?
Rhetorical question? You might also be missing the point of the article.
I'm not, but you did. My "Gee..." comment was meant to show that a high-quality PSU with a lower rated wattage can be better than a lower-grade PSU of a higher claimed wattage, so that people should look beyond whats on the box (and in the case of minimum output per rail, efficiency, and testing conditions
whats not on the box or the manufacturer's web site).
Feedback on your "How to select a PSU" guide, or what ever you want to call it. You might want to edit your "Recommended PSU Chart" to reflect that the PC P&C 510 SLI 510W rating is "Rated output through 50°C."
It used to be there. If it isn't now I'm not sure why I removed it.[/quote]Either you were confused as you seem to be now, or you forgot to put it there in the first place. You asked for input and that was easy.
Since you are such an expert on PSUs' you should make it clear to people reading this thread that quality, reliability, and tight power regulation are what count, instead of a cryptic "Comon Aries64" comment which less enlightened readers may misunderstand.
Yeah, it's too bad that "come on, Aries64" is much less useful than "neither of those Seasonics will work" when in fact at least one of them DO, and I posted a link to back up me. Try again.
Please.
You really don't get it. Still. You try again.
Stop rubbing heads with Operandi and realize that not everyone on this forum knows the differences in PSU quality and efficiency and how those differences can translate into the difference between an "install and forget it" experience and a troubleshooting seemingly random reboots and failed boot-ups.
First of all efficiency has nothing to do with it, and "quality" very little so, if the numbers are accurate. Second, random reboots (during games) I could understand, but I don't see why failed boot-ups would be a problem.
You still really, really, really, don't get it, DO YOU? You honestly believe that efficiency and quality have little or nothing to do with running an energy-hungry, high-end system? Is that what you think? So you think that a poor or lower quality, inefficient "500W" PSU is just as good as a PC P&C 510SLI? Efficiency drops as temps rise, so its' a safe bet that a cheapo PSU isn't putting out the claimed 500W at 50C. Maybe even 40C. And as far as the quality goes, I think you are doing readers a diservice by that crap is OK. And I AM NOT saying that Seasonics' are crap. Quite the opposite, as from what I have read they seem to be quiet, efficient, and reliable as well as well-priced.
EDIT: BTW, Its is a known fact that 512MB X1900s' draw more power than 512MB X1800s' and 512MB 7800 GTXs', which everyone except me conveniently ignored despite my statement about this and my quoted ATI recommended 12V Rail amperage. Why?
Because it is possible to have a system with 2 X1900XT(X)s in it and still have a total draw of less than 38A.
Unlikely, though possible.[/quote]Howard, why did you edit out your "Unlikely, though possible" comment at the end of you last statement? Its' OK, I put it back in for you and
bolded it. Anyone who wants to see Howard's post before his edit/deletion please email me and I will email you a screenshot of it. I don't know how likely or "unlikely" it would be to have a high-end, dual X1900XT(X) CrossFire system that draws less than 38A, but I believe in being thorough. I would rather have more than enough than not enough. How about you?
