Didn't you know dielectrics make noise when you pass a current through them?Originally posted by: jonnyGURU
Luckyboy lost me at "cap noise." 🙂
I'm sure he meant coil or transformer noise, but whatever.
Facts are facts. Luckyboy lacks them.

2) The OCZ PowerStream models are warranted better.
3) The idea that OCZ simply calls a company and tells them to repackage a product and send it out without having their own EE's dictate exactly what OCZ wants is nonsense. What, are you trying to say that OCZ simply goes on faith?

Me: just wondering, who's the OEM for mushkin's PSUs?
Mushkin Guy: toppower
Mushkin Guy: custom spec
Mushkin Guy: much better voltage reg
Mushkin Guy: we have consultant redesign vreg on 3.3 and 12v rails
Mushkin Guy: practially no ripple
Mushkin Guy: among best in class 😉
Me: so you'd say they're worth the extra money over a generic toppower?
Mushkin Guy: yeah
Mushkin Guy: it's like
Mushkin Guy: erm stock cobalt to the supercharged and then modified further cobalt 😉
Mushkin Guy: I mean reg toppower better than alot of PS
Mushkin Guy: but these are much much better
EDIT: I copied and pasted our Xfire convo pretty much word-for-word. The names were changed because I felt like it 😛.
Doubt all you want, I have no reason to jump into this thread and make that up. I've got a 1GB kit of Mushkin XP4400 from this guy that I didn't pay for (search for my RAM posts, I recommend value RAM all the way) and would never pay for because he had it laying around.Originally posted by: JEDIYoda

I seriously doubt your conversation...
becuase I have called 1/2 dozen PSU manufacturers and NOT ONE would divulge who made the PSU.......hmmmm

... I'm sorry? Power supplies deliver wattage at a fixed voltage(s), AFAIK. Or are you trying to say that voltage necessarily goes up once a power supply hits its limit?Originally posted by: Luckyboy1
Who really needs 650W?
Well, you'd have to define the word "need" as it fits your application. The truth is many of the heating problems people are running into with the more powerfull video cards has its roots in the fact that most power supplies simply are not up to running them, especially on the 12 volt side of life. If a given power supply can't deliver the needed wattage to run a component at 12 volts, it will try to make up that wattage in amps and that means more heat.

The truth is, from a complete answer standpoint, my 520 watt OCZ PowerStream is just barely adequate and that's not "best". Is it good enough?... well, that would depend on how you define "good enough". The way I define it is that if you've attended to total case cooling and you still are running on the hot side with any components, it's time to look to a more powerfull power supply.

Many things electrical and electronic will run on a range of voltages. If this is not the case, why do we even bother watching voltages or are concerned with it dropping any? I've seen video card run on anything from 10-14 volts. Did they run cool and well this way? No, but they worked. Again, as the power supply reaches the maximum amount of power it can produce on a given rail, the voltage starts to sag. As it does, the components demand no less wattage to run, so they try to a degree to get the shortfall in voltage made up in amperage and that means more heat.
This is why I ask people who say their power supply might be garbage to download and run under load of heavy applications something like Mommaboard Monitor that can keep track of high, lows and averages in voltages and temps. If the person's voltages are not sagging under load, I become less suspicious of the power supply. If the voltages sag by multimeter readings, the I ask them to confirm by multimeter their findings. This way, no probe or software or bios error can cause a false reading. If the voltages are fine by multimeter and don't sag, then I say stick with that power supply and look for some other cause for whatever problems they may be having. If by multimeter the voltages still show some saging under load of an application, then I say ditch the power supply for something more powerfull.

That is MOST DEFINITELY FALSE!!! Application preference merely means that the driver uses whatever you specify in game. The game/drivers dont choose for you!!the default setup has ?Application Preference? set. What this means is that no matter how you set up the quality levels, the game
(in this case, IL-2 FB) or application will choose what it thinks is the best setting. Most people wish to have their settings stick, so in the ATI driver control panel, you will want to uncheck the ?Application Preference? box.
no, your Soundblaster live card is not one of them, so get to lowering the hardware acceleration for sound

I never said anything about less power dummy! Power is in watts! I was talking about how the component needs a certain amount of POWER... that's in watts DUMMY! Volts X Amps = Watts! So, if the voltage gets lower and the card needs a certain amount of power, it will try to get it in amps instead. Come on, you guys really aren't this dumb? You guys from the website CWOS?
If you decrease the voltage then the switching speed of the diodes decreases, this may result in the videocard artifacting or just a full blown crash. Of course if the switching speeds don't decrease that much then it won't be a problem. As to the 5% rating, they are specified to work with a 5% variation, in engineering terms that means they will work with higher variation, but that they will manage 5% or more.Originally posted by: Luckyboy1
The chips require a certain voltage to drive a certain current. If the voltage drops so does the current. Components do not get to mix and match what current and what voltage it is running on....
Garbage, they can and do to a degree use a range of voltages from let's see, the 5% spec everyone is so fond of using as a standard makes for a range of values from 11.4 to 12.6 on the 12 volt rail and we've all seen posts where someone has commented their video card is running on less or more than those values by multimeter. What a component can't do is go without a certain wattage regardless. Again, if it can't get it from the volts, it will try and draw more amps.

You can undervolt CPUs, why do you think you can't do it for other parts?...
I think I just said you could do that. Didn't I just say people report stuff running on a whole range of values even beyond the 5% spec everyone tends to point to?
