[RESOLVED] PSU not powerful enough? - Page 2

post #11 of 39
Thread Starter 
What about the instant reboot using tomb raider :/ it prooves that it's not just with furmark. I tried that kombuster, but the card instantly throttles down when I use, so it's not a real test.
Yes I have upped the volt since originally it's at 1025 and I'm currently using my 850 Mhz with 1063.
That 850Mhz test was always great passed everything even furmark. But as soon as I ran it at the same time as prime95, poof instant shutdown again.
I'm so confused, don't fancy spending £100 for no reason, yet again someone else told me he had that same problem running 2 cards on sli. He only had a 750W PSU and they requiered at least 950W. When he up graded to 1000W he never had that problem again.

furmark can and will overload the gpu esp. on the 5xx series of nvidia cards PERIOD if krombuster is throttling down your card thats not because its a bad benchmark, actually just the opposite, its doing what its suppose to do by pushing your card without trashing it. here to show why furmark is not the best to stress with:
(btw, i know this is probably not your card but will still give you a representation of what to expect - more on that in a minute)
Power Consumption
Peak: Crysis 2 at 1920x1200, Extreme profile, representing a typical gaming power draw. Highest single reading during the test.

Maximum: Furmark Stability Test at 1280x1024, 0xAA. This results in a very high non-game power consumption that can typically be reached only with stress testing applications.


sorry to sound rude but whoever "they" are that is telling you that a 950 watt psu is required for a single 580 are complete ignoramuses. a 650 watt PSU is the absolute most that an overclocked cpu and overclocked single gpu will need.

here take a look at this list:
POWER SUPPLY REQUIREMENT FOR GRAPHICS CARDS

have a look see from another site:
MSI GeForce GTX 580 Lightning Xtreme edition review
Quote:
Power Consumption
Our test system is based on a power hungry Core i7 965 / X58 system . . .
Measured power consumption one card

System in IDLE = 174W
System Wattage with GPU in FULL Stress = 388W
Difference (GPU load) = 207W
Add average IDLE wattage ~ 20W
Subjective obtained GPU power consumption = ~ 234W
Recommended Power Supply

Here is Guru3D's power supply recommendation on the GeForce 500 series:

GeForce GTX 580 MSI Lightning (XE) - On your average system the card requires you to have a 600 Watt power supply unit.

btw, a little note on the site:
Quote:
Note: As of lately, there has been a lot of discussion using FurMark as stress test to measure power load. Furmark is so malicious on the GPU that it does not represent an objective power draw compared to really hefty gaming. If we take a very-harsh-on-the-GPU gaming title, then measure power consumption and then compare the very same with Furmark, the power consumption can be 50 to 100W higher on a high-end graphics card solely because of FurMark.

it still could be a problem with your PSU but it certainly is not the wattage. to be specific what is more important is the amperage of the 12 volt rail because that is what is needed to power your cpu and gpu. and looking at all the 600 watt BeQuite series; the lowest amperage is 18 amps among four rails. each rail is more than sufficient to power either a 6 pin (75 watts) or the 8 pin (150 watts) that a 580 will use with 18amps*12volts= 216 watts.

now comes back to the part of what gtx580 do you have? you posted a link to a pic of you general set up but yet to have stated what overclock you have on the card with what voltages.

you're either overclocking too much or you could have a 12 volt rail failing and if its a true multirail PSU, the OVP would be tripping. but you certainly do not need to get a 950-1,000 watt psu.

Finally someone that gives me a real answer, thanks a lot. No one told me I needed a 950/1000W psu.
I have the MSI gtx 580 Twiin Frozr 2, I can post the pictures right now, since my work firewall is blocking most websites.
I'll stop using furmark, as it is a monster by the looks of it. but then it does represent the worse case scenario I suppose, and in theory if an OC can pass a furmark test, it should be able to withstand anything thrown at it.

On that link you've just sent, a gtx 580 OC at 900Mhz (which is my target) does require a 650Watt PSU. There for my little 600 W isn't powerful enough especially with so much equipment attached to it and a CPU overclocked at 4.5 Ghz. Would a 750 Watt PSU be more then enough though? and what should I look for when buying a PSU?


My current clock speed is 850Mhz with 1063 Core Volt. it seems stable even with furmark on it's own. But if i run furmark and prime at the same time then poof.
Anyway i'll stop using furmark. But then why would it happen when I was playing tomb raider? Would running 3D mark firestrike demo for a couple of hours would be a good test, or should I run all the 3D mark test (demo, test 1, test 2, cpu, and combine?)

i found a few reviews of that card, i am glad chrome translates languages:
http://ht4u.net/reviews/2011/msi_n580_gtx_twin_frozr_2_oc_test/
http://www.bitsandchips.it/hardware/9-hardware/446-msi-n580gtx-twin-frozr-iioc?start=4

looking at the specs in the second link, you're hardly overclocking with a ~6% increase in the core clock ~5% on the voltage. btw, did you need to up the voltage? so i highly doubt you're putting much if any load on the power consumption ATM.

i cannot say that its not your PSU but i certainly am sure it not the wattage, more specifically, the amperage on the 12 volt rail when looking at the specs of what i think you have:
http://www.bequiet.com/en/powersupply/239
Max. combined power 12V (W)540

the card, cpu and hard drive motor won't come close to 75% (405 watts) of that which is entirely "roomy" enough even when running prime95 and benching the card. btw, good for you for pushing you system like that thumb.gif but i will have to admit most of the time when having a hard reset it is a problem with the psu. however there have been an issue with the ram which will also cause a reboot. the issue happening when playing tomb raider is a bit of a head scratcher; is that the only game time it happens besides stressing the system?

though do you have the time and patience to test the ram? its a bit of a long shot but very possible to be the problem. also just for "fun" would you be able to swap both the 6 and 8 pin PCI power connections to the card? having a multi rail 12 volt system may but shouldn't kick in the over current protection in one of the rails.

hopefully my trouble shooting suggestions make some sort of sense and worth the time.

Maybe your GPU isn't stable at those clocks. Try stock GPU speeds with that 1.063 voltage if it shuts down again then you can at least rule stability out, if it does not that go to 1075mv and test your 860 clocks again. Use Heaven 4.0 on max settings as it's very demanding and won't destroy your GPU like Furmark will.

I would never use furmark for anything.

ok so th3illusiveman I've just done what you said, furmark stock speed which is 800Mhz and volt 1075mv and it worked ok, but when i've upped the volts to 1100mv with 800Mhz the computer hard reset. What should I make of that result? Even with no OC on, just changing voltage, the computer hard reset.

I've bought 3D mark 13 (the one with fire strike), if I run the demo mode for a couple of minutes is it the same as running heaven? or heaven is still better?
Aswell in 3d mark, i'm not sure what I should been running in a loop:
- the demo (constant video with no loading time in between),
- graphic test 1/2
- combine

A part from the demo, there is a loading screen between each test, or each time the test is re done.

I have no idea how to do that (ram or change the 6 to 8 pins) , if you can explain quickly i'll do it smile.gif

Well if you're getting a hard reset with only changing the voltage then your PSU comes into question again. Was this with everything else at stock? (maybe downclock your CPU to default clocks and voltage for now just to rule that out). 3DMark has the Firestrike Demo which is very taxing on the GPU so it's a good alternative to heaven 4.0 try looping that.

so try looping firestrike with 1100mv GPU voltage and stock clocks and stock CPU clocks/voltage.

Ok so after 8 mins of fire strike extreme , with everything back to stock speed and voltage (cpu and gpu), appart from the gpu who had it's core volt at 1100mv, the nvidia display crashed.

So what now?

Hmm, headscratch.gif

you can't be maxing that PSU out with a single GPU... Its a Gold Standard PSU too so it's very good quality and rated for SLi and CFX... But then again your GPU shouldn't crash at stock settings with high voltage.

  • Are you monitoring your GPU temperatures and specifically your VRM temperatures? (Using either HWinfo64 or GPU-z you can see your core temp and vrm temp)
  • If your temps are under control then maybe try a clean install of new WHQL drivers (avoid betas for now) http://www.geforce.com/drivers/results/57096

i'm running out of ideas here redface.gif but i'll see what you report back and if i can try and help.
