You forgot enermax! Or did you?
I've been overclocking for years using enermax PSU's and haven't had a single PSU-related issue. They're whisper-quiet too.

Check out the Tagan TG-480-U01, reviewed here.
Very quiet, extreamly well built and tons of power.

That power supply has been changed. Internal design is a lot different from the pictures of the reviews.
Yes. I have one and I opened it to verify the differences. I took pictures of inside and posted on silentpcreviews.com. Check users compaints about their power supply.

another vote for pcp&cooling. just picked up a 510 express and love it.
like assasin my +12 sits at 12.16

how come no one mentioned the fact that the 600watt OCZ blew up a few dozen computers recently, taking all the attatched hardware with it?

The OCZ PowerStream series includes a 420W, 470W, 520W and 600W model. I have been thinking about getting a PC Power & Cooling Turbo-Cool 510 dee-lucks for more than a year. It is "not out of my range", but . . . . let's face it . . . . I can be tight with the ducats, and I have paid for it with a 500W PSU that falls down above a 20% over-clock -- on the 12V rail.
For this, the adjustability factor recommended the OCZ to me, and I looked into it further. Never mind the reviews of things where the author starts out saying "Today, we are reviewing the XYZ model by ABC corporation", where page after page focuses on packaging, appearance, modular ease of installation, LED lights and other nonsense. You want a reviewer who has take the item nominally into a testing lab, and ideally with several other products in the same class.
The OCZ PowerStream 520 is conservatively rated at 520. More than one review notes that it should really be named "the 600". Then again, what does that say about OCZ's PowerStream 600?
The rail voltages, compared to six or seven other PSU's mentioned in posts above, are phenomenally clean, with very, very little variation under heavy load conditions. If the 12V rail is set to 12V (a nice feature with the external adjustment screws and LED's provided), over-clocking and a heavy PRIME95 torture-test will not cause a drop in voltage of any significant degree. It may drop by a few thousandths, but that's about it.
Here's another paradox. Many industry publications and "commentators" have noted that the "efficiency" rating of PSU's is subject to a lot of hype. Essentially, the larger the "percentage" rating, the less AC power is lost to heat in the conversion to DC. I've looked at PC Power & Coolings ratings across their Turbo Cool line, and they are all 70% ratings. But these are not described as "minimum" efficiency, but rather "typical" if I'm not mistaken. That means that under "normal" load, you can expect a 70% efficiency. Some cheaper PSU's are hyped to have a 65% minimum efficiency with a 75% typical value, but the same PSU's don't hold up at maintaining voltages under load testing. [That's why I've finally come to the decision-crossroads over a PCP&C Turbo Cool or another alternative].
Now -- the efficiency rating is also related to heat dissipation. And I find that OCZ PowerStreams are rated by the manufacturer at a "MINIMUM 63%", but reviewer after reviewer says that the units are extremely cool-running. Couple that modest rating with the understatement about the maximum power the unit can provide and sustain -- an understatement chosen to name the product. The fact is, you can't be sure exactly what game OCZ is playing with either its ratings or this unit, except that they have understated its capability, and that other manufacturers play around with their efficiency ratings, and that there is "apparent efficiency" versus "actual efficiency" to confuse how those measures are taken. And it is very likely that the "game being played" by OCZ is to understate the quality and performance of the Powerstream line.
The final thought here is that OCZ has really produced some stunning products in the memory module market -- and they all get high marks. If they were to attempt to produce a shoddy power supply, would that be consistent with their other products, which really depend on clean and reliable power supplied at rigorous voltage specs? I don't think so.
What I think is that OCZ has thrown down a gauntlet to the PC Power & Cooling king of the mountain. And what I think is that they've come into the market offering the same quality for a lower price. And what I think is that the Turbo Cool's prevailing two-year-long asking price of $220 per unit will not last.
Anyway, the only way to find out -- is to find out. UPS is delivering by Wednesday. I won't get it into my "MOJO" until after Xmas -- too much clutter, confusion and distraction leading up to the 25th. I'll tell you what I think a week or two after I've got it up and running.

My next PSU will be a OCZ. I will have to mod it for silence but still they are a company by overclcokers for overclcokers so you can bet your product will be a good one gluk
ed... if you want to read the mos scientific PSU reviews I've seen go over to silentpcreview.com they are quality in all thier reviews but I particualy like thier effecinty calculations and noise instumentation. Check it out.. OCZ did very well BTW. But enermax is number with 80% effecient.

Here's where the mainstream view of "genuine manufacturing" may introduce a bias.
Some other forum member posted a remark earlier in this thread asserting that the OCZ PowerStream 520 was really a "made-over" Topower 686P6. Looking at the photos of the OCZ and the Topower taken of their "innards", it seems unmistakeably clear: there is a high -- very high- probability that the assertion is "TRUE".
It would seem that OCZ chartered a special design or "issue" of the Topower, and subcontracted much of the manufacturing. This, by itself, is not particularly deceptive, and we cannot be sure exactly how much "value-added" OCZ infuses into the product.
What we do know is that they warranty the product for five years. This is equivalent to the Turbo-Cool warranty. However OCZ chose to "get into the PSU business", it would seem that they had much riding on it. They have to produce a power-supply that will complement their memory-module accomplishments -- and even the nice reception raised by their "DDR Booster".
Technically, you can say they "only been in da bidnis fo' less than a year." The initial reviews I've seen were published last summer, one of which appeared in a Brit e-magazine named "Enquirer" [Tech only; no stories about Jennifer Lopez giving birth to an infant fathered by aliens from another galaxy.]
But realistically, OCZ has been in the PSU business as long as Topower has been in the PSU bidnis. What else could you say?
