OCZ is a very capable mid-to-upper-end brand and I have a lot of positive experience with them.

Take offense? He never recommended anything, just commented on the power supplies that other suggested.

Let's not about my opinions and overall PSU recommendation habits, based solely on a two sentence post.

Image was not necessary.

You're the project leader here on the PSU forums. It is not unjust that we fellow enthusiast/experts weigh in on your arch of recommendations.

Like I said, even the ModXtreme should be on your list because it's far beyond the kind of PSU you tell everyone will explode in two hours.

Well, one can pay $75 for a ModXStream 600W, or $60 for a Rosewill RG-630 that's equal or better in most respects. One could buy a StealthXStream 700W that has a tendency to die (due to incorrect package +12V Schottky whose joints go cold) or one can get something that won't fart and die in one or two years (thankfully the original SXS 700W finally seems to have gone away).

New StealthXStream II series is good. ZX series are good but not priced well. Most of their other stuff... Just not worth mentioning really, most of their new stuff isn't priced well and most of the NOS stuff floating around isn't particularly great.

So you're seriously claiming that OCZ PSUs will fart and die?

Great, why don't we all just buy PCP&C from now all and break our piggy banks..

And you're comparing an OCZ to a.. Rosewill?!

I don't even have the strength to argue about this one..

I believe you're deliberately misinterpreting what I say. I said the StealthXStream 700W used a +12V Schottky diode of an incorrect package. The leads are too big to perfectly fit the solder holes. So the joints go cold and the +12V rail drops to zero, the unit dying silently. It usually takes one to two years for the joints to go, but it happens to a very large percentage of SXS700 units.

And Rosewill has come a long, long way since 2005 when they were using Youngyear and Deer crap. They have many high quality units, including some built by Sirfa, who are one of OCZ's main OEMs in case you didn't know. Sometimes even the same platform as OCZ units.

But you have to take a stand somewhere and form a hierarchy.

PCP&C
Silverstone/Corsair
Antec
OCZ

Chinese Crap.

80% of all power supplies are made in China, with another 15% or so in Taiwan. Rest in South Korea and India and elsewhere.

And that 80% figure includes most enthusiast power supplies. Heck, the HCP-1200 is made in China, though I'm not sure which lab my ES came out of.



You can't go by brand. You have to go on a unit by unit basis. What are the average electrical characteristics of this unit? What is its build quality like? Who built it? What topology is used? Are there any design flaws?

You can't just say "XX" brand is better than "YY" brand.


Also, PC Power & Cooling is owned by OCZ.

But it has to be simplified.

PCP&C is no more, but when you bought a PCP&C PSU you had no doubts about its quality.

Just like you have no doubts that a GTX 580 is better than a GTX 560..

There has to be a definitive, simple way to know/understand the PSU industry instead of memorizing component quality and reading reviews for every model that comes out (most of which don't have reviews).

I mean, unless I can just come to you every time I need to know if a PSU is good or not and inevitably fill your inbox..

The methodology must exist/be created to differentiate between PSUs that are worth buying and PSUs that aren't.

If brands aren't the way - what is?

if you understand the concept of a psu you can tell whats good,bad or mediocre by just looking inside rolleyes.gif

there cant be a set standard to class power supplies because the list would be so varied it will just end up confusing everyone

There is no easy way.

Corsair better than OCZ? Sure, except the StealthXStream II 600W is better than the CX600. But the CX400 is marginally better than the SXSII 400W, but the SXS 400W is marginally better than either. The OCZ Fatal1ty 550W and 750W were just meh, but the Fatal1ty 700W was a very solid unit (built by Impervio).



It isn't like graphics cards or CPUs where you have easy performance metrics and only a handful of manufacturers. There are four x86 CPU manufacturers (Intel, AMD, IBM, Via) and only two matter in the PC space, and there are five GPU manufacturers (Nvidia, AMD, Intel, Matrox, S3) and two of them are completely irrelevant. You have easy benchmarks that anyone can run, and most products are derivatives of the same family of designs.




There are hundreds of PSU manufacturers, each with dozens of designs based on dozens of topologies, and there are hundreds or thousands of brands of components that they can use. And those hundreds of OEMs distribute through more hundreds of resale brands.


PSUs aren't like other things in this hobby. It's a complicated subject, and one that can't be boiled down to a handful of easy numbers.
