Feedback?
Well it consumed a night of my life.

Yeah, it was good. very good information, great link and I've got a bit of a list going now.
Forced to really, since I found out that there is some kind of Freak Power Supply issue involving Antec modular PSU - the NeoHE series (the one I was gonna get) - and the ASUS motherboard that probably has been the top selling board for the past 2 years.

This might be interesting - in a forum about power supplies - because nobody seems to know why this modular PSU from Antec won't work with these mobos from the #1 mobo maker. A PSU mystery.

Since I learned so much from Johnny's tutorial and now have had the added information from your link, I now know what I need and what I have now is TOTALLY inadequate (18A on one 12V rail). It's amazing that my computer has been running for a year.

But now the PSU seems to be failing anyway. It was weird. Like VOODOO. Right after reading johnny's comment that he wouldn't run a power supply that performed outside of some strict threshold (like 11.9V to 12.1), Probe II began reporting that the power on two of my rails was near 5% below and the 3.3V rail was at 3.09. The LCD also started going black, then coming back on, and this happens about every ten minutes.
Probably you're amused.

I found one psu I started to like but then discovered there was a flaw in the cabling, and who do you think the reviewer was - johnnyguru.
There's a new OCZ GameXStream powersupply but I can't find the specs anywhere.

One thing I wanted to ask you is there was two ways to calculate your power requirements. The second way, called the quick way, the number was actually different. Why is that?

I have to get a power supply yesterday and one thing is sure. If I hadn't read this thread and then the link you gave me, I would be buying the wrong power supply with too little power again.
Thanks.

PC Power and Cooling Turbo Cool 1Kw and 850 SSI run at 90% efficiency. Some review sites have reported their experience with those 850 SSI units to be higher than 90%.

Picking the right power supply

Watts don?t mean squat!! Know how to read the label!

All a wattage rating is on the box of a power supply is the total capability of ALL of a power supply's rails COMBINED. The 5V, 12V, 3.3V, -12V, -5V and 5VSB capability are all added up to calculate a power supply?s ?wattage rating.? That total number really tells you nothing about the power supply's actual capability.

First you have to ask, is that wattage continuous power or maximum peak power? Some power supplies will give you output ratings based on what the power supply can continuously output, while others give you peak power. For you audiophiles, this is similar to the difference between RMS and Peak. Some companies will actually rate a power supply at what it can continuously put out, but with a tolerance of 10% +/- from actual spec! Intel?s ATX spec only allows for a 5% tolerance!

There's also variables that come into play like ?what was the temperature at which the testing was performed?? ?For what period of time was the testing performed at the specified wattage?? Basically, you should look at the amperage each rail is capable of and then just consider that the power supply's BEST CASE SCENARIO capability.
The first thing you can do is to try to figure out your computer's WORST CASE SCENARIO load. There are several calculators on-line that allow you to "add up" your computer's power. Unfortunately, the bulk of these give you a final calculation in wattage. Later on, I?ll give you a little formula I use to calculate how much power I think I need on the 12V rail (the most important rail in a modern PC.) 3.3V and 5V just follow.

You?ll soon enough figure out how important the way the manufacturer distributes power across the rails really is. If you have a 500W power supply with 40A available on the 5V line and you're using a Prescott with SLI video cards, you might be in trouble because the 5V line alone is using up 200W of that power supply's total power not leaving much else for other rails! Given that most power supplies give you 20 to 30A on the 3.3V (which is way high by today's standards, but even 30A on the 3.3V is only 100W) and split up about 20W for negative voltage and stand by, you're only left with 180W for the 12V rail. That's only 15A! Mind you, we're talking maximum combined peak power, but better safe than sorry, right?

If you don't have the time or resources to do this, then just do this instead: Try to figure out if your PC is going to be 5V heavy or 12V heavy, and then buy the biggest, best quality power supply you can afford with the load balanced most appropriately for your PC. For example: If you have a Pentium III or an Athlon XP board without an ATX12V connector (like Biostar Socket A motherboards never have the 2x2 connector) then something with a relatively high 5V is most suitable for you. pIf you have a Prescott or an AMD64, consider something with a high 12V like an Ultra or an OCZ. If you have PCI Express video card or cards, consider something with a really, really high 12V rail, like one of the SLi approved power supplies on nVidia's website.

So now back to helping you guys and gals read a PSU label. Use this as a reference: http://www.jonnyguru.com/PSU/NexthermPSU460/P1010227.jpg

This one is very simple. This power supply gives us 30A on the +3.3V rail and 30A on the +5V rail. Underneath these two, you?ll see where the maximum combined capability of these two rails is 150W. That means, you can load up the +3.3V to 30A by itself, and you can load the +5V rail up to 30A by itself, but you can?t load them both up to their maximum simultaneously. The rails are not additive. You?ll also see 0.5A on the ?12V and 2A on the +5VSB. I?ll get back to the 12V rails in a minute.

Note that the total power of this particular power supply is 460W.

Ok? Now look at the 12V rails. There?s two 12V rails (I?ll explain why later) and they are rated at 18A each. The maximum combined wattage of those two rails is 32A.

What?!? But 18A plus 18A is 36A? Like the +3.3V and +5V rails I just mentioned, +12V rails are not additive. You can load each one up to 18A, but you can?t load them both up to 18A.

Now let?s go back to the ?watts don?t mean squat? phrase. I don?t want to slam any brands, but take a look around at some 500W and 600W units. You?ll actually find that even though they may have more ?total wattage? than this particular unit, this unit actually has more USABLE power on the 12V rails. Pretty interesting, right?

I noticed you recomend an ULTRA PSU and feel I need to disclose something here: I hope there are no hard feelings between jonny and I. JonnyGURU is a Moderator for ULTRA Products and works for their company. We are all aware of the reputation that ULTRA products have.

This is how the paragraph looked that I read:

If you don't have the time or resources to do this, then just do this instead: Try to figure out if your PC is going to be 5V heavy or 12V heavy, and then buy the biggest, best quality power supply you can afford with the load balanced most appropriately for your PC.

If you have PCI Express video card or cards, consider something with a really, really high 12V rail, like one of the SLi approved power supplies on nVidia's website.

I noticed that he recommends an OCZ too, AND he recommends any one of the SLI approved power supplies on nVidia's website. I've also read his reviews and noticed that he recommends a number of power supply units that have passed pretty close inspection and testing.
I suppose we should find out if he works for all these other companies too.

While he could have put a disclaimer in at the beginning of this article that reveals these secrets, I think he has said that there are many good quality power supplies and ULTRA is just one of them.
I know if I had spent a great deal of time researching power supplies (which I am doing btw) and I bought one of them, and then I wrote a huge article about power supplies I'd plug my power supply as being one of the good ones.
I know that I expect a reviewer to own a computer and own top quality components. I also expect that if the reviewer mentions several top quality models of whatever component he is reviewing, that he will own one of them.
If he was to plug only one manufacturers's product while hiding the fact the he worked for that company, then this would matter, but when he often indicates throughout his many writings and reviews that there are alot of good products out there, then I don't think it's the same.

You should arrive at the same number. I just condensed the two multipliers into one.

Perhaps you input the wrong numbers into the calculator? 0.9/12 = 0.075, so it should be the same.

EDIT: I didn't include the 10% safety factor in the quick method. It's optional in the longer method.

Hardly "top secret" info there, Sherlock.

But still... not like I designed the X-Connect or anything or that I get paid on number of units sold. If you're implying I'm some sort of shill, I sure as hell aint a good one.

I don't consider what I do any different then when a review site with Antec advertising all over it reviews an Antec power supply.

I will let you know when I do get my own PSU out there. Believe me... I'm working on it.

EDIT: And I won't have the audacity to review my own product. I'll let someone else have that honor.

Anyways thanks for the effort in writing this article jonnyGURU.

Sort of a back handed compliment after what you said, isn't it? No hard feelings just the same.

And thanks for having my back Hari.

Hey Googer - Do you know where Hoffa is buried too?

I have known Jon worked for Ultra almost as long as Jon has known. (Was I the 3rd to know? After Lois? Did Chantal understand? )

I have read all of his reviews, and have been lucky enough to be able to call him a close friend for nearly 7 years. (You just HAD to move! :|)

He has NEVER weighed heavy towards Ultra, and has lambasted them if the unit he is testing deserved it. (See some of his reviews on http://www.slcentral.com/)

Yes, BEFORE Jon started helping Ultra (Before he was a full time employee), Ultra powersupplies had some issues, (Many blown out of proportion by some "news" sites) but he has dedicated himself and his FAMILY to helping Ultra better their quality and appeal. Now - they are poised to become one of the better PS brands, and as long as Ultra listens to Jon, they will continue to improve.

Anyways thanks for the effort in writing this article jonnyGURU.

Nice smartass comment.. :frown:

Anandtech (And the PC community) should be THANKING him we have someone so dedicated to his work AND the community he serves.

*Disclaimer - I run an Ultra power supply and case - so am I a schill too?

 

[jonnyGURU]

Thanks bro. It doesn't matter what these guys think as long as I'm happy doin' what I'm doin'

It's 2006, bro. It's been more than 7 years. Look at our join dates. That's only 6.5 years ago and that's just from when the old Anandtech forums crashed and they were replaced with Fusetalk. We were working at TCWO location #2 at the time. Before that, there was TCWO location #1 (the card table next to the fridge,) George's Computers, the first stint at ASI and then Millennium.

It's been a long strange trip my friend!

 

[GalvanizedYankee]

We have had a couple members who worked for AEG posting on this board. I don't
believe the OP is one. One must use care, "Don't throw the baby out with the bath water."

jonny, based on your review and several others I bought the Enhance 0560 that is one and
the same with the Silverstone Strider 600watt and you did rate it VERY highly.
(none left for the tardy)

I do not think Googer's intent was evil or mean spirited. I was suprised to read it this AM.

I feel better knowing that you are an Ultra Forums mod jon. So I can sent ppl with Ultra difficulties
to that forum, knowing they will get real help. It will force me to discount future reviews
you do for Ultra and consider other reviews of thier products.

...Galvanized

 

[JEDIYoda]

Johnny I never read a review from you that was loaded with BS!!
I also never read a review of yours that IMO was slanted in anyways towards a particular product!

In fact the first thing that struck me about you was how when you do a review you are totally unbiased.

I knew what everybody else knew about you.
But what I found refreshing about you was how unbiased you were.


To be fair towards the ULTRA brand of PSU`s.
I have friends who a few years ago wouldn`t have touched the Ultra brand.
But based on reviews none of them from you johnny Utlra IMO keeps getting a bad rap for no reason other than what transpired in the past!

The Utlra`s get real nice reviews and real favorable comments lately!!

Of times we get closed minded concerning things such as PSU`s or Heatsinks or any number of things!!

Anyways Johnny you keep being you. The unbiased helpful person that you are to those of us who might have PSU issues or problems!!

Again my hat goes off to you Johnny!!!

Like I said in my response to Googer, I have no intention of ever reviewing ANY Ultra product I have any involvment with. And I will GLADLY give a sample to anyone willing to perform their own UNBIASED review of it.

Wait a minute... I worked at CompUSA before I worked with you. That doesn't count as "working in the industry?"

 

[mikeford]

Any chance of a short disclaimer at the front that says when all this fancy smancy PS stuff is important? 99% of consumer products have cheese PS's, but work for years, why are yall getting so excited?

For SLi or lots of ram, etc etc. or if you have some kind of trouble or PS shutdown, sure, buy a better one, but seems to me most users get by just fine on the generic grey box that comes with the case.

Wasting half a kilowatt on a PC is so not green.

You're quite mistaken.

A power supply only supplies power on demand. You're actually doing the NON-GREEN thing by using a cheap power supply because they're running less efficiently (typically < 60% @ 25C) to produce the same amount of DC power as a better power supply (typically > 75% @ 25C.)

And it's always wiser to not risk blowing your stuff up or cause mysterious lock ups and crashes with a cheap power supply by getting something that's quality.

 

[JEDIYoda]

I can attest to that Johnny!!

When I first joined these forums I was always making fun of those who had nice PSU`s with good specs!

For years I had always run with the same generic PSU that came with my Aspire cases.

Never had a lick of problems ever!

Until one day I started getting mysterious reboots and mysterious blue screens of death.

After talking with a friend on these forums I decided to get a name brand PSU. We won`t go there because thats not what this thread is all about!

Yet-- I switched after doing much looking and talking and calling different brands tech suppoort to see just what I was getting myself into.

I went with a nice PSU and I have not had any of those issues since.

But let me say when i was having those issues I was running 9 case fans...not counting the heatsink or the Video card and I was running 3 harddrives and ..well yuo get the picture.

What I will say is that sure a generic PSU will get you bye in a pinch. But do you really want to power all your new $$$ equipment with a PSU that would cost $20 if you were to buy it from a store??

I don`t know why people always skimp on there PSU when without the PSU your equi[ment can`t run....hmmmm

 

[mikeford]

Sorry must have left out a emoticon, using a good efficient power supply is nice, doing your surfing on a PC that only uses 100 watts is nicer.

We are in a technology blip right now where performance systems use huge amounts of power, but sensible low power systems aren't more than 2 years behind the leading power hog edge, and over the next decade I expect low power to replace the current demand for performance in most market segments.

I don't mean to derail your thread, but seems like it doesn't apply to most people, and I am sure some who have read it have needlessly wasted time and money.

!!!!! $20 !!!!! It took me half an hour to convince myself I needed the $11.49 instead of the $9.99 from Geeks.com.

 

[JEDIYoda]

There are power supplies that will definately do the job for $20.

But let me ask if you were to pay $1,000 + for a new mobo and CPU...does it make sense to get a $20 PSU?

You when it comes to PSU`s you get what you pay for and then you alsdo can pay too much, we all know that.

I have seen generic PSU`s blow literally blow up and take out the mobo and the CPU as well as the hard drives?

All that from a $20 PSU.

I have seen a $75+ PSU blow up and take nothing out....not even hurt one piece of equipment.
Why...quality and workmanship.

If it interests you here a website where they have taken off the covers of cheap to expensive PSU`s. That will illustrate my point very well...

http://www.badcaps.net/forum/showthread.php?t=1178 -- part 1

http://www.badcaps.net/forum/showthread.php?t=1262 -- part 2

On paper what you are saying is true Mikeford but even people who have systems that are 2+ years old still have compnents that they would not like to have to replace anytime soon.
Also if you have to replace a PSU and opt for a newer higher $$$ model you can be assurd that most likely when you to get a new system you can swap the PSU that you have into the new system.

Hope that helped!!

Googer several things come to mind.....

Becuase this site Anand tech takes advertising dollars from companies whose product they ewview does that meake Anand tech any less honest??
Same applies to Johnny!

Does it matter who might pay somebody else as long as those people desire the truth be printed concerning there products?

Think about it for a minute.
In the buisness world a truly progressive company wants to know the truth and would rather pay for the truth-- even if the truth is bad than to put out a crappy product based on some reviewers loyalty due to monetary considerations!!
makes sense huh?


Please drop it dood!!
All your doing is reinforcing what others have said about you on other threads.

Thank You!!

You "do not know" because you are very, very naive.

Why would a company PAY ME for this thread? I mentioned "Ultra" once in this whole thread and it was in the same sentence as "OCZ."

Are you really that thick headed?

That paragraph was cut and paste from my own website and, believe it or not that's up to you, was written LOOOOOONG before I ever did anything for Ultra. And the reason why I even mentioned it in the first place had NOTHING to do with even KNOWING people at Ultra or working somewhere that sold Ultra, but was because at the time I wrote it, multi-12V rails were pretty much non-existant. The two products that came to mind when thinking of power supplies that had really large 12V rails were: The Ultra X-Connect 500W, X-Finity 500W and 600W and the OCZ 520ADJ.

I would think if Ultra was paying for this thread, they'd want a little more copy than that. Furthermore, I used a picture of a label off of a Sytrin power supply when I was talking about PSU labeling. Maybe if I used an Ultra label I'd get paid more money!?!?

Do you maybe think for a minute that I insisted we NOT get into brand comparison because I do NOT want to be put in the awkward position of having to "defend" a particular brand because of an affiliation to that brand???

There's nothing wrong with you pointing out my alliances. It's not a big deal to me. And I don't think it neither adds nor subtracts value to the thread. But to say that it's even a REMOTE possibility that my activity was paid for is so ming blowing to me, I have a roll of duct tape on stand by just so I don't lose any potentially useful gray matter.

Jesus H. Christ, I've been a member of these forums since they opened and have done everything possible to be as helpful as possible FOR FREE. You'd think that would give me a little more benefit of the doubt than to take payment for a thread from a company I'd only been working for a couple months! You can choose to believe me or not, but the only forums I "represent" the Ultra name on is the Ultra forums. So I totally understand where Galvanized Yankee is coming from. I'd probably be the same way! But to think that someone PAID ME to post a thread?!!?!?

I'm sorry... I'm just so floored by your density that I don't even know what to say anymore.... Watch your head. Some satellites have lost their trajectory and are gravitating towards your skull.

Johhny, just ignore him. Everyone else does (or tries to anyway).

On a side note, albeit actually on topic (for the thread), I have a question. If operating in a hot environment (such as the garage), would removing the casing of a PSU help or diminish the cooling for the PSU components? It was just a thought, for an upcoming project...

Nevermind the EMI problems that will cause, removing the housing will have the same effect to your PSU that taking the side panels off of your case will have. A PSU housing and it's fans are made to "channel" air out of the PSU.

That said, you can do this....

1. Make sure you have an exhaust fan in the case OTHER THAN the PSU fan(s.) That way the PSU only has to worry about exhausting itself and not the whole chassis.

2. Get a PSU with front to back coaxially mounted fans. It's the best airflow you can give a PSU.

3. Mount the PSU upside down in the case. You'll notice that typically when a PSU is mounted in a tower, the PCB is at the top, so heat rises into the PCB. Flip it around and the heat rises into the airflow.

Hmmm. Guess I should have been more specific. I'll post pictures when I get everything up this weekend. Then I'll either create a new thread, post in here, or just PM you. This will be a, rather unique, situation. Good point about the EMI though, as I hadn't thought about that... Once again, thanks for your input.
