How much wattage should my PSU, I think it might be dying.

[NOSDuco]

I have been having graphical performance issues and I think the cause of these problems is my power supply. I don't think it is giving the video card enough power to run at it's optimal speed. I will post my specs below but how much wattage should it be using when I am just browsing the web and when I am playing BF3. Thank you - NOS

Specs:
Intel Core i7 CPU 870 @ 2.93GHz
16.0GB Gskillz RAM
XFX AMD Radeon HD 6950 Double Dissipation
1.5 TB HDD
750 Watt Corsair PSU TX750

That 750W should be sufficient. If you suspect the PSU, get with corsair and work on an RMA.

I would imagine you can boot to desktop and surf with a 350W PSU, and I would venture to guess that AMD doesn't recommend higher than the 750W to run that card.

I am using a multimeter and it shows 120 Watts when surfing the web and 200-230 watts when playing BF3. Are these measurements too low?

Those numbers sound about right.

If it is not the PSU that is lagging my FPS in games then I have no idea what it is because I have even tried different graphics cards and not even that improved my FPS and they all can't even play BF3 on Low when they both used to be able to play it on Medium - High.

What may be an obvious question, have you been playing with drivers? You say that you've tried multiple video cards, which means you've been swapping them in and out. This sounds like a driver has become corrupt, and you're compounding the issue by swapping out cards. A full removal of drivers, followed by a nice clean install, may be in order.

I actually tried doing that before I did a swapping of the cards.

If you look in my specs, I run that rig bone stock with ultra settings on BF3. Not sure what your exact issue is, aside from a little less GPU grunt than I got, but I agree it should run Med to High settings even without any OC.

Yeah, and I can't even run on low without lagging terribly. At this point I have no idea what the problem could be.

PSU's do not 'lag FPS in game'. So look elsewhere.

How many GB of ram does that 6950 have? If its the 1GB (did those come with 1GB?), there is your problem.

It is 2GB and it has 2GB....

This is odd! I was able to play on medium with a Athlon X4 630 and 5770 1GB

Exactly, that is why I think something is wrong and I am trying to figure out what is wrong... I have no idea what it could be at this point.

big time your psu should be fine i ran two 58xx on a tx850 for a year+ , a tip , I have an old slow sata 40gig drive i have a simple windows build on For My rig ie , whql certified stable drivers for all but not updated or anything, ie a garuateed booter and worker, with a bench or two on , if in doubt i plug it in and boot, youd be amazed at the heartache its saved me as it often looks hardware when its an os corruption or some such thing

So this 'lagging' you are experiencing. Can you elaborate on where you are seeing this lagging and describe it more? Do you have Vsync enabled?

 

[LGV]

I think thets card have 2 gig.

Please post cpu-z pic-s.
Along with BIOS pic. ( memory, cpu)
Would be nice to see the idle temps and in play both on CPU and GPU.
Both connector to the GPU ok?
check all cables.

Then we may could help.

good luck

I open Fraps to check my FPS and it says I get around 50 on High but the gameplay is very lagging, it skips frames, mouse lags, etc. Just a generic lag but all the time.

CPU-Z:

GPU-Z:

I downgraded to CCC 11.8 earlier today to see if that would help my issue but it did not but it did not make it worse.

Temps:
GPU: I get 50 Celcius when browsing web and around 60 when playing Blacklight Retribution (which also lags on the lowest settings).

Cables:
I just checked all the cables and I tried using different cables that came out of the PSU but that did not make a difference.

BIOS:
My BIOS doesn't tell much because I am actually using the motherboard out of a Dell Studio XPS 8100. If the motherboard ends up being the issue I am going to upgrade the motherboard as long as the processor to a new Intel Core 3rd Gen that came out earlier today.

Ram speed low, but doubt thats it.... (you arent even at your rated speeds).

With FPS around 50, vsync is not enabled, is that correct?

V-sync is not enabled, and I have tried using different RAM.

 

[EarthDog]

I didnt ask about different ram.. Im talking about the ram SPEED. You are running it at 1333Mhz vs 1600Mhz its rated for. I doubt thats the issue wnut its worth trying at this point.

What am I supposed to do to the RAM to make it run at that speed then?

 

[EarthDog]

Up the memory multiplier.

 

[NOSDuco]

Up the memory multiplier.

For the GPU?

 

[NOSDuco]

Up the memory multiplier.

How do I do that?
