How does the quality of the components in an OCZ compare to that of say, a Corsair/Seasonic? I ran the 520w Modstream for a while and as far I was concerned it was a great PSU. I was considering the 700w for my next build but if the 620w Corsair uses higher quality internals then I might go for it as it seems to come very highly recommended.

Have you been to JonnyGuru's website, jonnyguru.com? Spend some time reading his reviews. Does a quite thorough examination and stress test on each power supply unit he reviews. Actually uses an industry-standard load tester and also manages to measure ripple at load, both things a lot of sites cannot or neglect to do.

His use of the SunMoon load tester moves him, in MHO, into another class of tester for power supplies. You ought to read how and why he tests like he does. Very good read. And while you can test a power supply with cards, motherboards, and the like, without an oscilloscope to examine ripple at load, or being able to actually load to stated limits, really doesn't show how "good" or "stable" a given power supply is.

Case in point......Enhance power supplies. Found at eWiz, for one place. Usually not spoken about much as they tend to be mostly an OEM supplier for ps "manufacturers" like Silverstone, for instance. (You do know most power supply "manufacturers" aren't really making their own but instead are having them made for them to spec, like Corsair does by sourcing theirs from Seasonic.)

Take, as another example, PCP&C....they don't make a damned power supply at all but instead source theirs from two manufacturers......Silencers originally were made by Sparkle and are now made by Seasonic. Turbo-Cool ps by PCP&C are actually made by Win-tact.

So, are the Seasonic-built PCP&C Silencers worth the premium over the actual Seasonics or Corsairs? Well, Corsair gives a 5 year warranty on their power supplies unlike PCP&C, and rate their output at 50C. PCP&C rate Silencers at 40C.....10C lower in operating temps. Significant? Maybe to some people looking for the best value for their money. Similarly, Corsair uses a LOT of 105C rated capacitors in their ps (almost all the significant caps are 105C rated in Corsair ps), Silencers don't have quite as many 105C caps.....a few 85C caps inside, instead. Add to it the modular cables and I think the Corsair presents a better value than the PCP&C selection.

How and why JonnyGuru tests like he does.

Who "makes" who in power supplies....or why you cannot trust the UL number (their easily purchased to look like you made your own.)



Now about these asinine comments:

To answer the first.....why would the PCP&C be thought to be defective? The Silverstone was out of spec on ripple, which the PCP&C was not, and the Silverstone was shutting off at high load, again which the PCP&C was not. He even compared the Silverstone to its OEM equivalent, a SevenTeam ST1000E-AD, and found the Silverstone unit was way out of spec compared to its identical OEM twin. So, that's why he obtained a new Silverstone sample and, mysteriously, the original problems disappeared. Sometimes bad units slip by, tard.

As for the second inane comment.......if you'd bothered to post WHY Jonny uses value as part of his evaluation score, then you would have presented the whole story. But, as per your usual trollish behavior, you pick and choose your inflammatory statements very carefully as to incite as much flamebait as possible while distorting the facts.

No wonder you're labeled a troll on JG's site and likewise well on your way to be labeled one here, too.
 
Well after analyzing the whole situation I have come to the conclusion that there could be 3 reasons to get a high end 1 KW PSU.
1, The unit would most likely last a lifetime as it would be under less than full load and would run cooler.
2, The components in a PSU of this type would most likely be high quality and output much cleaner power.
3, The way computers change it is likely there will be in the lifetime of this PSU a use for this much power.

So yeah I get it .
 
Another reason to get it..haven't seen anything lower that has the 4 PCIe connectors required to run 8800GTX's in SLI..my roomate is using the 1kw BFG power supply to run his, he originaly bought an Enermax Galaxy, but it was DOA.

You have some personnal issues.........lets look at what you stated.....we shall do this one at a time.....
I don`t see Jonny contacting PC Power & Cooling to see if perhaps the first 1k unit he tested might have been defective,,,,lol -- that fact remain you take 100 PC Power & Cooling PSU`s and you take 100 Silverstone PSU`s...you know the one where Silverstone sent Jonny a "defective " unit and I dare say the PC Power Cooling ubits have little if any quality control issues compared to thew Silverstone......IMO Jonny should have dockewd the Silverstone unit 1/2 a point for having quakity control issues....

since when does price figure in on the quality of a PSU???
Things that make you go hmmm.. Price doesn`t figure into quality at all and a PSU should not be docked for price if it lives up to its rated specs and such,,,,after all nobody is twisting your arm to buy an expensive PSU....yet there cistomer service is tops and there RMA if needed has most of the time a less than 24 hr turn around that is to say they will ship you a new PSU overnight or even same day before you ship yours back to them....

To answer the first.....why would the PCP&C be thought to be defective? The Silverstone was out of spec on ripple, which the PCP&C was not, and the Silverstone was shutting off at high load, again which the PCP&C was not. He even compared the Silverstone to its OEM equivalent, a SevenTeam ST1000E-AD, and found the Silverstone unit was way out of spec compared to its identical OEM twin. So, that's why he obtained a new Silverstone sample and, mysteriously, the original problems disappeared.

But, as per your usual trollish behavior, you pick and choose your inflammatory statements very carefully as to incite as much flamebait as possible while distorting the facts.

Your commernts are not inane? rofl.....Because i disagree with portions of what Jonny says I am a troll? Habve you looked in the mirror lately?

Now lets get down to what I consider totally rediculous comparisons by you....
Take, as another example, PCP&C....they don't make a damned power supply at all but instead source theirs from two manufacturers......Silencers originally were made by Sparkle and are now made by Seasonic. Turbo-Cool ps by PCP&C are actually made by Win-tact.

who you talking to?? we all know that PC Power & Cooling don`t make there own PSU`s.......seems to me like you didn`t!!
Yet for years PC Power & Cooling PSU`s have been considered by a good many people to be right up at the top of the pack....so can we infer that Seasonic made PC Power & Cooling a damn good PSU?? I thnk we can....so one question..why since Seasonic was making PC Power & Cooling PSU`s was Seasonic not making there own PSU`s? I find it rediculous that you actually believe that because Seasonic makes PC Power & Cooling PSU`s that there fore it`s a Seasonic PSU.....rofl....thats why you are infering?
You have little if any clue concerning as some eould say what goes into making a custom PSU!!
Yet by looking inside you have really no clue hardly other than the ## that Seasonic makes them...
Yet tell my why PC Power & Cooling was the first to issue 5yr warrantys?
Why PC Power & Cooling PSU`s were the first to be rated -- 40c and even 50c??

So lets address some misleading information in your post......
Corsair gives a 5 year warranty on their power supplies unlike PCP&C, and rate their output at 50C -- thats not true at all....except for the Silencer Series; PC Power & Cooling gives all there PSU`s a 5 yr wanty...and they rate there PSU`s at 50c.......so why not come clean and be honest??

But thats okay I forgive you for your lack of knowledge about PC Power & Cooling PSU`s...its obvious that you fail to grasp that PC Power & Cooling giving 5 yr warranty`s and test there PSU`s at 50 c long before most compaies were willing to do so..in fact most companies were using the 25c standard...

I private message Jonny quite a bit and I have no issue with the way he tests thing...in fact I was not even serious about why Jonny went to get another PSU to test....I find it ironic when you have to get a replacement PSU to retest when you are sent a defective PSU from a company...that smacks of a quality control issue..lol

Personally for me money is not an issue when it comes to buying a PSU or anything else.
Thus I could care less about a "value" rating...I am more concerned with quality and workmanship which is why I only purchase PC Power & Cooling PSU`s...I have 2 -- turbo Cool 510`s and a 1k.....

435 posts and you think I care about your opinion...rofl..keep it up your an accident waiting to happen.....so you work for Corsair huh....rofl

I have to agree.

The 8800GTX's maximum thermal load (the maximum amount of net heat it generates, which includes some assumed inefficiency in the PSU) is 185W. HardOCP took some current measurements and estimated the actual draw from the PSU around 150W. So two of those is 300W. The QX6700 has a TDP (Thermal Design Power, very close to the maximum power the chip can draw) of 130W. Now you're up to 430W, or about 36A on your 12V rail/rails.

Unless you're putting a lot of other high-power components in this system (hard drives, most likely), you just don't need a 1000W PSU. Now, you'd probably need a 550-650W unit to get an adequate amount of slack on the +12V rail(s), but not a 750-1000W one. This assumes, of course, that you're buying a quality PSU that can actually deliver its rated amount of power. And that you are picking PSUs that are properly engineered for modern systems:

This "600W" would have problems. There's only a maximum of 38A on the +12V lines, and the layout of them would make it hard to deliver power properly to both video cards:

http://www.newegg.com/Product/Product.asp?Item=N82E16817171011

Whereas this "550W" can deliver more power on the +12V rails, and all the 12V rails are 18A (making it much easier to keep all the rails under the rated current limits):

http://www.newegg.com/Product/Product.asp?Item=N82E16817151027

In case you don't believe this, SPCR beat the heck out of this exact PSU, and it was able to output 15+A on all four +12V lines simultaneously at >40 degrees C for an extended period of time.

http://www.silentpcreview.com/article656-page4.html

Seasonic also has a 650W version of this PSU, and an "M12" line (500/600/700W) that is very similar but has detachable cables.

If you want to overclock (and especially overvolt) like crazy, that's another story. You'd quickly be looking at 500-600+W required on the +12V lines, and then you would need a 750-850W PSU. Ditto for having more than a couple hard drives, especially if they are 10KRPM or 15KRPM models.

Interesting reading, we need more people fighting the "spend $59864684500 on a 8473635000W power supply or your PC is dead and u will lose da game lolz" mentality. I mean, the numbers simply don't add up!
 
for what it's worth, i ended up going with the ocz proxstream. with rumors of ati's next card pulling nearly 300w each, 1000w doesn't seem like such a ludacris idea if you plan on keeping the psu for many years. thanks for all the thoughts and input, i appreciate it.
 
Lucky for you HardOCP just did an excellent review of the OCZ power supply...it got a lukewarm review at best and was recommends as a "don't buy."

LOL...oops...just read two posts up.

It seems that regardless of how much power you "need", this PSU offers very stable power for any configuration. At $300 for a PSU that is not only "future-proof", but performs above industry standards, it's an excellent deal in my mind.

1, The unit would most likely last a lifetime as it would be under less than full load and would run cooler.
Click to expand...

Temperature depends entirely on the efficiency of the PSU, how much power it has to output, and how good the cooling/ventilation is. I haven't seen much evidence that running a PSU at far less than its rated capacity significantly increases its lifespan. In fact, this often results in significantly lower efficiency, which will result in higher temperatures. Most PSUs are built for maximum efficiency at something like 75% of their rated power output.

2, The components in a PSU of this type would most likely be high quality and output much cleaner power.
Click to expand...

You can have very high-quality PSUs that are not 'big'; most people would define 'high quality' power output as things like low ripple or voltage fluctuation, and a good-quality PSU can output clean power even close to its maximum ratings.

With cheap PSUs, running at way less than the rated amperages may reduce voltage fluctuation. But I haven't seen evidence that good PSUs suffer in this regard when loaded near capacity. Buying a lot more PSU than you need generally won't hurt in terms of power quality, but it will cost a lot more.

3, The way computers change it is likely there will be in the lifetime of this PSU a use for this much power.
Click to expand...

The problem is that if you're looking at spending $300-500+ when a $100-150 PSU would work fine -- you can buy the $100-150 one now, and if you really need a much higher-power unit in the future, they will probably be cheaper by then.

IMO, if you're not almost certain you will need a significantly bigger PSU within 6-12 months, don't bother buying something that is way bigger than you need. If you're buying an 8800GTX now and planning to get another one in six months -- sure, go for the 600W PSU. But spending hundreds extra for something you may need a few years from now seems kind of silly to me.
 
The only question I have left is this- Will there be any "real" disadvantage to using a 6 pin -> 8 pin adapter for the next gen PCI-E power cords? I'm assuming this will be possible as I can't imaging them making everyone buy a new PSU when the cards come out.

HardOCP Review
Not sure how you missed this. It was posted on the top of the front page. IMHO HardOCP is the only reliable PSU reviewer out there. And the OCZ failed their testing and provided maximum sustained output at only 800W tops. D'oh!

"270W of power consumption" -> put two of these in crossfire and you're at 540w required power BEFORE you even plug anything else in. 1000w psu's are not as silly as some may think for high end gaming rigs.
Click to expand...

Nobody has provided any kind of remotely reliable source for the 240+W power numbers. I'm skeptical. Although I didn't think that we'd see single GPU cores with 500 million+ transistors, either. If it is in the 200+W power range, and you want to run them in Crossfire -- yes, you'll finally have something to use your 1000W PSU (or at least the 750-850W one) for.

In any case -- only in rarely should you think about buying a PSU based on what you think future hardware might use. If you're considering building an R600-based system, at the very least you should wait until the official specs are announced before buying anything.

Unacceptable in my position - I'd would be required to have a spare. I could not be without a system for weeks! 🙂

What the hell are you talking about? It's a standard NEMA15 to IEC that happens to be 14AWG... so?
 
Are you currently thinking of building an SLI enabled Nvidia GeForce 8800 GTX gaming system with an Intel quad-core processor and a couple of hard drives in RAID? Well if you are then you need a 1000 watt power supply right? Wrong, but how can this be wrong with so many 1000 watt power supplies becoming available! In fact you don?t even need an 850 or 800 watt power supply to safely operate such a system. After recently building this exact system we discovered that the maximum power demand created by this configuration was just 530 watts.

It's probably loud because the guy has a bad PSU. I have the exact same model and I NEVER hear it no matter what I'm doing. Heck, my entire PC is so quiet you may not realize that I leave it on (if I turn off my server, that PC is a little bit noisier).

Personally, I haven't been a huge fan of OCZ's PSUs. I have a PowerStream 520W in another PC and my voltages aren't that great for a relatively low load. Although if I remember correctly, Jonny also found the PS520 to be a weak PSU. I'm thinking about replacing it with a better and quieter PSU.
