I just can't let it go, no. Saying PC Power & Cooling is the best of the best, just isn't right. If you're really into spending that sort of money on a powersupply, Zippy should be on your list. Throwing in my background was done simply because you clearly stated that I didn't know what I was talking about. I understand warranty is a big thing for you. Let me ask you this: Do you really expect that you'll use that 510 PSU in 5 years from now? Simply looking at the upscale of powerusage of PC's in the last few years answers that question - No. Of course noise ripple plays a large role in the quality of power the PSU delivers. But I can assure you that the Forton PSU's have excellent power quality. I don't doubt you when you say you don't experience any voltage fluctuations on the rails of your 510, but may I ask how you measured that? I sure hope it wasn't with a mulitmeter. Besides, I never said the Pc Power & Cooling PSU's were of low quality. No, of course they aren't. But they are overpriced, and the price does not justify the so called "quality" this unit has over other units. It's sort of wrong when you say the 510 is the best of the best, when it's clearly not. I wouldn't have commented if you suggested the 850 or something similar (the prices of those are nuts anyway). You also did not answer my question about how PCP&P acutally tests the output of their PSU's. And about the 850 Zippy. It's a SINGLE RAIL PSU (1x 12V - 60A), while the PCP&P is a 3-rail PSU. With all your electronics background, you should know that it's harder, and much more expensive to build ONE fat rail, rather than several, smaller rails. As a bottom line, I really just can't understand the whole PCP&P fetish some people are having. Yes, it's a very high-end PSU, but no, it's not the best money can buy. And forking out unncessesariy amounts of cash just to have "that brand", seems a bit foolish to me. It also appears to me that you got annoyed when I criticized Pc Power & Cooling one bit. That, to me, borders to fanboyism. Now... it doesn't appear to me like it's any use discussing this with you.
