Hello, does anyone have a power use chart for different brands, memory, versions, of these 4 cards 570, 580, 670, 680. I need to know the wattage idle and loaded of each of these, just for the cards not the whole system. I need these values to be pretty accurate. Thanks!
 
For reference stock versions, you can google their TDP; for example, "GTX 570 TDP". TDP is what Nvidia conservatively says is an average amount of power the reference card at stock clocks will pull (you are unlikely to see much more than that).

GTX 570 TDP: 219W
GTX 580 TDP: 243W
GTX 670 TDP: 170W
GTX 680 TDP: 195W

When you get into the overclocked versions that various brands put out, their TDPs will be all be different but usually higher. But there are theoretical limits.

All video cards will pull up to 75W from the PCI-E slot. The PCI-E 2.x and 3.x standards allow more power to be pulled from the slot, but to date no card is known to have been made to pull more than 75W from the slot, presumably to ensure maximum backwards compatibility and safety.

Video cards additionally pull a maximum of 75W per 6-pin PCI-E power connector and 150W per 8-pin PCI-E power connector.

So, if a card needs no PCI-E power connectors, it cannot pull more than 75W. If it needs one 6-pin PCI-E power connector, it cannot pull more than 150W. If it needs two 6-pin PCI-E power connectors, it cannot pull more than 225W. If it needs one 6-pin and and one 8-pin PCI-E power connector, it cannot pull more than 300W.

Ok Thanks evilsofa, In the toms list the Zotac GeForce GTX 670 Amp! 2 GB GDDR5 1098 MHz pulls 199 watts is this card overclocked? What is stock for the 670? 680? Also, do they use the same chip just the 680 is overclocked or no?

Also is it possible to Underclock a Gpu to save power?
 
What application is this for (since you mentioned accuracy in the OP)? Because there are some issues to consider.

The chips are the same design but they are not necessarily the same. By this I mean they could have different power consumption figures. Identical models of video cards can have different power usage figures depending on how much precision you are going for.

Power usage is related to voltage and clockspeed.

Also "load" is a bit hard to gauge. Different programs can have a rather large difference in terms of how much power is used.
 
OK, I know this is going to sound crazy hence the reason I didn't mention it, but I plan on using one of the cards inside a Laptop build I am planning on doing. So I want to how much power I am going to need on the 12v rail as well as the Total power draw as accurately as possible that way I can make my DC to DC Psu as energy efficient as possible. None of the pico PSU's will power this with a 3770k right?

Yeah what do you predict the wattage to be when word processing? Internet Browsing? And using Premiere Pro CS6?
 
So here are my questions I think they might have got lost in the thread.

In the toms list the Zotac GeForce GTX 670 Amp! 2 GB GDDR5 1098 MHz pulls 199 watts is this card overclocked, that would be why it uses more than the TDP? What is stock for the 670? 680? Also, do they use the same chip just the 680 is overclocked or not?

Also is it possible to Underclock a Gpu to save power?

Yeah I looked at these,
http://www.tomshardware.com/charts/2...Idle,2980.html
http://www.tomshardware.com/charts/2...Load,2981.html

except the figures differ significantly then other reviews like these
http://www.guru3d.com/articles_pages..._review,9.html
http://www.techpowerup.com/reviews/A..._Cu_II/26.html

Which one should I go by?
 
I think you're being abit ambitious here man.

A 680 is ~200w, a 670 ~185w. A 3770k is ~80w stock. Factor in about 50w for mobo + fans etc. You'll be pulling about 315w. I don't think any PicoPSU will output that reliably or continuously.

You could underclock them, but stability could ecome an issue? Just get a lower card.

PS: Techpowerup reports the wattage of just the card. Most other sites do full system wattage.
 
LOL I know, Its a little hairbrained.

I know it draws a lot of wattage, I am studying EE so I was going to build a 350~400 watt DC to DC PSU. I was just wondering if anyone knew of a DC to DC PSU that would work off the shelf. Most of the problem is the PCI-E connectors for the GPU.

I can't use a different card. I need it to be compatible with CS6, even though this card is still not supported now, leave it to adobe to take forever to add a card to the supported list.

Yeah all those sites are suposed to be the wattage of the card but they differ significantly.
 
Oh man, CS6 won't even use a 1/4 of a GTX680. CS6 barely uses half of my wife 460. You're goin WAY too big.

Thats a reasonable count at full load, but if you don't reach full load, you're never going to come close to that.

3770k's 77w TDP will idle at a quarter of that, the new 6xx series cards will idle at 10's of watts, not 100's. You could easily run that kind of hardware at idle off a pico psu, but I'm not sure i'd be comfortable with the potential for something spiking the load, causing everything to power up all at once and totally exceed the PSU's ability to keep up

For Photoshop of course not however editing 4k 5k Video footage in Premiere Pro will be different. I need Cuda Media Acceleration and only a few cards do that mostly the Quadro series.

That's what I was figuring Web browsing and Word are not going to be running this at full load. The only problem as I said is with the Pico not having a PCI-e port. Does anyone know of a DC to DC that does?

If you use the Dvi port on the motherboard how does that work does the Video Card get used or only the Intel Graphics?

Yeah what do you predict the wattage to be when word processing? Internet Browsing? Almost Idle? And using Premiere Pro CS6?

Apologies, forgot about the video side of things. I'd expect encoding to use the full force of the GPU, again likely exceeding the PSUs max wattage.

There are a bunch of quadros that don't require a PCI-E connector. They can max pull 75w from the board, then 80w from your CPU and your within the limit of the 200w Picos. I wouldn't put much else on there, maybe a SSD and a fan.

Yeah I was thinking of that but the Quadro's are very pricey, and are a whole lot less powerful. I'll keep it in mind as a option.

Kind of?

Tricking the quadro drivers into thinking your geforce card is a quadro works, but only increases the performance by a tiny bit.
 
Anyone for these,

What is the stock clock for the 670? 680?
 
Gonna be blunt here, this is the first time I've ever seen anything like this. But I doubt your going to get answers quick. If recommend a more engineering friendly board, as most of us are more inclined into the enthusiast side of things and not the engineering side.


In a side note soft modding has been useless for a while as the devices have been increasingly locked down
 
OK risqu3 Thanks I look into a engineering board.

Anyone for these questions? Doesn't seem like I need a engineer for them, lol. :)

You're better off going with a 7950 and undervolting/clocking it . It's better at compute functions . The thing is with the 6xx series is that even if you underclocked them, when you played a game they'd go back to their boost clocks or higher effectively making your underclock irrelevant not mention they also lack voltage modification so amd has an advantage in power consumption if you wanted to enforce an absolute limit

Depends on how you're setting up the GPUs. If you're keeping the GPUs seperate, only the Intel graphics is used when the DVI port on the motherboard is used. However if you still have a dedicated GPU in the system, that card will still be drawing power even if it's not connected to a monitor. But If you enable Lucid Virtu, you can kinda use both in the sense that the video card will be turned off during non-3D tasks but will be turn on during heavy GPU usage.

Too many variables involved to provide any sort of accurate or even ballpark range figure.

I can't use a 7950 because I need the Mercury playback acceleration and that isn't a supported card.

Hmm ok so there is not way to totally turn off the 680 (Short of Unplugging) when I don't need it, and just use the descrete GPU. Using Lucid Virtu is there a performance loss when using the motherboard DVI instead of the cards, does it use memory or cpu to do this?

What other variables do you need to predict the wattage to be when word processing? Internet Browsing? Almost Idle? And using Premiere Pro CS6?

Ok found them duh, I am a idiot I don't know why I didn't go there in the first place.

It'st more of not everyone's definition of a usage pattern is gonna be the same another person's. In other words, web browsing could mean just looking through Wikipedia with only one window open or having multiple flash heavy websites open as well as dozens of tabs open. Both are considered web browsing but both are gonna have totally different power usage figures. Or Adobe Premier Pro CS6 for example: one could be just be cutting and pasting various clips together or re-encoding a blu-ray rip to a smaller file. Both are considered you using Premiere Pro CS6 but obviously are different in terms of load. Not to mention that people will generally have different applications running in the background taking up CPU cycles and HDD performance which can further affect power figures. Basically, there's a lot of variance with PC usage and setup that one cannot entirely apply from one person to another in regards to measuring power load.

Then there's the issue of measuring the power itself. Unfortunately the Kill-A-Watts and other cheap similar devices that people use to measure power aren't accurate with PC hardware and can actually vary from device to device. So even if you have the unusual case of two people using the same hardware, exact same software/OS setup, and exact same usage scenarios, the two people could still provide different power figures if you're using two KAWs to measure the power usage.

No I understand what Lucid Virtu does. I am just looking to make this run as power efficient as possible when I am running it on battery. Lucid Virtu in "i" mode will work for this no?

And what I was asking above was if there was a way to turn off the 680 fully without disconnecting it. I just want to be able to save extra power on this when I don't need the 680.

I do realize that there are a lot of generalizations that must be made when calculating wattage. I am just looking for some figures on what wattage I should expect the 680 (only the 680) to use when doing these tasks.

I don't need the figures to be perfect hence the reason why I said predict.

THanks!
 
Thread for the PSU here http://hardforum.com/showthread.php?t=1730660

In this thread I am trying to figure out If Lucid Virtu will help with wattage any by how much? If there is anyway to shut off the 680 totally without manual disconnecting it? Either by software or by cutting power to the 12v rails and a couple pins of PCI-E? I know I can't disconnect while the system is running

What predicted the wattage of the GTX 680 will be when word processing? Internet Browsing? And using Premiere Pro CS6?
 
with picopsu, the continue load off powerfet does not exceeding 8A, usually there are 2 in pair, you can always cascade more powerfet on the same rail, but remember, those pico psu also using switching voltage regulator, the impedence and capacitance has to be recalculated,

E*T = (Vin - Vout - Vsat)* (Vout+Vd)/(Vin-Vsat+Vd)*1000/150khz {v*us)

VSAT = internal switch saturation voltage = 1.16V
VD = diode forward voltage drop = 0.5V

the E*T = ur inductor selection

Cff= (31*10^3*Rx)
for forward capacitor value

usually the buffer cap value = ur load*3 (12*3 = at least 35V cap) and depend on the coil, calcute the ripple for proper uF

i hope that answer ur question,

so the easiest way is to buy a 120W pico PSU, replace the FET, Inductor, Cap, and maybe regulator, however, u will need heatsink, as i found out the hard way, no load = 65C and after 5min into temperture thurshold...

any more Q ask, i built that for my robot and need to power my CUDA GPU, Q9100, Kinect, DSP so on
 
Wow allenpan Thanks for that info! So how much wattage will the 120w Pico do I switch those components? Will I be able to get 400w out of it?

In this thread http://hardforum.com/showthread.php?t=1730660 someone suggested that I use two of these. http://www.short-circuit.com/product/m4-atx.html

Can I really use two of those PSU's Separately? Don't the other rails need to be used on the power supply or does that not apply to this type?

And we got to get some pictures of the Robot! :D
 
the M4-250PSU,..

one advice change those 5 electrolytic type capacitor to solid state capacitor, the picture is not too clear, but i can guess they are at least 1000uf for the forward capacitor (input buffer), 1000uf SS cap is not cheap, that is why they use electrolytic..

problem with that is i have 2 high torqe stepper motor with gear box, this require "high" starting current, those electrolytic cap works, but die after 2000 start up cycle...

and u might need cooling on that DCDC PSU, looks to me those fet should need heatsink at least when on load...

i am thinkign i might buy one to replace the DSP PSU,

as battery, i use 2x motorcycle battery, why? i have spare car chager, and once the robot is working perfect, i will replace with something modern...

this can help you for cascade multiple PSU
