A good power supply doesn't just provide you with ample output. Increasingly, vendors have put a bigger emphasis on delivering power more efficiently, too. We're testing five 80 PLUS Platinum-rated power supplies in the 550- to 600-watt range.

jupiter optimus maximusWhat happen to Seasonic? They have the 520W fanless SS-520FL Platinum version. No PSU test is complete without a seasonic to compare to, in my own opinion.
they asked for vendors for the PSUs. Theres the offshoot chance that seasonic declined the offer. On other sites, the 520w fanless seasonic unit was compared to Rosewill's 500w silent night unit. The seasonic unit I believe in that review barely edged out a victory.

iknowhowtofixitEither the Rosewill FORTRESS was defective or your calibration was off for the last test. Your o-scope shots do not match those of other highly credible reviewers. Also, I'm curious of your testing methodology, but it was not listed.
I believe this is still applicable to all of the power supply testing our German team does: http://www.tomshardware.com/reviews/psu-test-equipment,.... I'm waiting for confirmation that I'm right.
Edit: Yup, that's the correct testing equipment/procedure!

Sometimes in reviews like these there've been products that produce disappointing results compared to well known manufacturers. So why do they send their stuff in the first place knowing that their product is of lower quality than the competition. Do they gain something from these reviews? Just curious.

By reading this article, i just thought of a great idea and help for us users, a Best PSU for your money guide, i think that would be incredibly helpful since PSUs are hard to buy and to know wich ones are really good, of course i know that is a lot of work, but it could be like once or twice a year and not monthly like Video Cards and CPUs, what do you think about it?

But two of these products stand out from the crowd: Cooler Master's Silent Pro Platinum gives us unprecedented power efficiency, followed by the value-packed Rosewill Fortress 550.Quote:
Most of the samples we reviewed exhibited minor flaws. For example, Rosewill's Fortress 550 exceeds the maximum allowable ripple voltage on the 12 V rail, which is an indication of cutting corners in circuit design or component quality.Your priorities are obviously backwards. Rosewill's entry, by your testing, failed to meet ATX spec by producing an unacceptable amplitude of ripple on the 12V rail. By definition, this is a fail. This isn't a minor flaw, this is violating spec. A failure can not stand out from the crowd (at least in a positive sense). Now, there are other posters here that dispute your results, but you don't have that luxury. Both your results and summary comments indicate that this unit is a failure no matter how good the efficiency, price, or other metrics look.
You can argue the importance of efficiency versus DC output quality all you want when the unit meets spec, but all of the components in your system rely on PSUs to actually meeting spec in order to function properly. Without meeting spec, there is no way to guarantee components will work properly. In fact, failing to meet spec pretty much guarantees that some component somewhere will not work properly. I've seen enough devices (granted poorly designed) fail to work properly with PSUs that had ugly DC quality, but were technically within spec to recommend one that is out of spec.

I would like to see a fully modular PSU review.
Also, the difference in cost between the Gold and Platinum rated models seems to negate the power savings one would realize by going with a Platinum model. Since I do run a few of my machines 24/7, I am curious to see where the efficiency lies for low power consumption for a variety of 80+ certified models as this level of power consumption occupies a large majority of the up-time (70+%).

I think the PSU is the most important component on the machine. If it fails or over-volts a rail it will kill components. So I usually get the highest effeciency PSUs because I can be sure they would need good build quality in order to get that rating. Last one I did, I stuck an Antec Earthwatts 550w platinum in a machine. I liked how it was not that expensive for a platinum psu, I can live with 1% lower effeciency.

Zagen30Or, you know, power savings, coupled with not needing 700-800 watts.
The power savings over a proper Gold or even Silver are often too small to matter with low wattage systems. If you don't needs 700-800 watt PSUs, then getting a cheaper lower wattage model that's still high-quality means more for the money and more money that can go somewhere more important.

Are you accusing Tom's of not being objective in this review? If so, then you'll have to do better. Rosewil, although they sell many products on Newegg, is not a part of Newegg. Furthermore, according to reviews of that Rosewill PSU from other sites, it would seem that Tom's simply had a defective unit.

A quality 700W PSU is enough to Crossfire/SLI even the highest end cards. The ~500W range is more than adequate for any single-card configuration + OCing. Typically a high quality 500W will run the same as a a lesser 750W, so why wouldn't I want the more efficient model?

dirtyferretno internal build break down? i don't think jonny guru and hardwaresecrets have anything to worry about in competition.
jonnyGURU is a place I go to for hardware tests as well, but I wouldn't put them above Tomshardware by any means. Frankly I think he showed a bit of leniency and bias in this article:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=...
The article points out build flaws that I would have flat failed the unit for, stamping it with a big "DO NOT BUY" in red letters. Instead, he says it was a good unit that just didn't compete with the better products.
I can easily see someone buying a Zeus because it's on for a sale price - "johnnyGURU said it was good enough, why not save some money?" Why not is because 3 years later those little ugly solder joints are going to come around to bite you in the behind. Mine took out my mainboard and CPU with it (after the 3-year warranty expired of course). Thanks, Silverstone.
I didn't read reviews on the Zeus until after the fact because I trusted Silverstone. It was a bad move, and Silverstone is the reason I now tell people "Don't by just by brand, buy a PSU that you've read good reviews of." But if a site isn't very clear about the problems of a product, a potential user isn't going to be forewarned, and jonnyGURU is being a part of the problem here instead of the solution.
Tomshardware was one of the first sites that starter testing computer PSUs - and telling us how bad they were. This site is in no small part responsible for the increase in quality we have seen in the last decade. Now, I do think Toms has changed a bit, not all for the better, and they are just as capable of being a bit biased or sloppy as anyone else, but jonnyGURU is NOT someone to hold up as a standard for PSU reviews. Yes, the site does a good job, but it doesn't do a great job.
I'm not intentionally picking on jonnyGURU more than Hardwaresecrets or anyone else, it's just that the particular review of the Zeus stuck in my mind so I use that as an example. These are all good sites (If I had to talk "best quality" today I would say Anandtech.com; of course they aren't infallible either), but just like the PSUs themselves, you have to read them with a clear head and open eyes and pay attention to the details. So, like, I know that if jonnyGURU gives a "7.5" for build quality, that means a "don't freakin buy if it's the last PSU on earth" in my book.

What's with the fixation on efficiency ? To me, voltage stability and ripple are the most significant properties of a PSU. This article provides 50% of that information making it useless to me. The ATX spec allows 5% voltage fluctuation whereby the minimum I consider a requirement for great overclocking potential is 1%. When voltage is flopping around all over the place under highly variable loads, it makes it difficult to maintain stable OC's.
How important is efficiency ? Let's assume 4 hours per day on weekdays and 8 hours per day on weekends ...... or 36 hours a week. Let's use 92% and 90% as the range of efficiency in this article.
36 hours x 4.3 weeks per month x (550 watts/1000 watts per kw) x (92% - 90%) x $0.10 per kwhr = $0.17
How many peps just went "Holy crap, I'm glad I read this article....now I can save 17 cents per month on my electric bill" ?

I'll rely on a site that provides a historical database of hardware tested that goes well into the double digits of units so I can make a valid comparison.

We've been told why the dollar amounts change each month. It is because pricing is constantly changing, so Tom's is trying to keep with the times instead of give us less relevant numbers. The Best for the money articles have nothing to do with what cards are sent by what companies because they don't rely on cards being sent by companies, they rely on performance data from many of Tom's tests and reviews.
Both getting editors choice doesn't mean that one isn't better than the other and is thus not comparable to something such as a Superbowl (I may not be much of a sports fan, but wouldn't a tie be settled by overtime or such anyway?). Tom's gave clear and logical reasons for their recommendations.

The review you linked wasn't done by Jonny or OklahomaWolf, who are the two main reviewers (and respected members of the PSU world). Jonny did do the review about the PSU you are so aptly whining about dying after the 3 year warranty period. It scored well, but that was 7 years ago. Power supplies have changed significantly and so have the standards in which we grade them by.

JonnyDoughIf you run high end cards you need a PSU with 700+v. Do the math.
My point was explicitly that some people don't run multiple high-end cards that require that much power, and they might, for some unfathomable reason, decide they want a more efficient power supply. If you're SLIing a pair of 680s, of course you're going to go with a much higher wattage PSU, but at the same time I don't know why you'd be looking at an article that is only covering PSUs below your needs.

JonnyDoughI agree, it would be nice to get 400w 80+ Platinum PSUs. With a 6-year warranty from a reputable company I'd probably spend $20 more and get one.
My only issue with Platinums at that low power point is that they hardly make any difference. It'll save what, three, four watts over a proper Gold? Added reliability and warranty, I can understand those, but being a platinum at that point is like arguing the advantages of a 100MHz speed boost on a CPU that's already well beyond 3GHz. It's little more than a buzzword in such a situation.

JonnyDoughIt's 8 watts, and that's per hour. Over the lifetime (say 5 years) of use that's quite a bit of electricity my friend. At $20 it would be worth it, if for no other reason than to minimize the environmental effect of using more energy.
It's not likely to be anywhere near eight watts and that's not a lot of electricity even over five years. It's not going to impact the environment positively at all (not that there's anything wrong with wanting to help the environment, but the added electricity used to make the more complex PSU components will be greater than any power that you save through it) and its not even going to amount to $10 of electricity saved unless you have huge power bills.
Like I said, it'd pretty much just be a buzzword. A platinum would make a much bigger difference in PSUs around or well over 1000W in systems where the power consumption is high enough that the small efficiency improvement will make a considerable difference.

Or on any wattage, for that matter.

I agree. Bronze seems to be the current standard for quality PSUs, but I would love to see that move into the silver. I'd love even more to have a price competitive "gold standard" but I think we might be a bit of a ways from that still. With more efficient PSUs comes higher manufacturing costs. People still try to skimp on a PSU so they are still able to sell cheap crap ones.

Although it looked nice, we weren't big fans of the overpowering chemical smell the bag was emitting.i'm guessing some one enjoys the chewy treats of protein that crawl about and breed like rabbits every one else refers to cockroaches. i have a washer machine that cures that problem, works on dirty clothing also.
i always find it refreshing to smell that bug killer in a new refrigerator. i can rest easy knowing it's not a roach motel and source of infestation.
