....... Im unsure if PSU can handle it. I have the OCZ 600W psu. Just wondering if you guys think it can handle such a beefy card. I'm fairly new to all this.

It should be arriving today hopefully in the morning, but if the PSU cant handle what would you recommend? My MOBO doesn't support SLI and I dont plan on upgrading it for a long while, hence why I'm buying this card.

Thanks for your help in advance

Should be fine, you might want to reduce your cpu overclock to the point where you don't have to increase the voltage (power scales as the square of voltage).
 
thanks jak, unfortunately i haven't the first clue about the overclock on the CPU as I bought the Xenomorph system, which OCuk sell and it came overclocked to this speed. This is my first gaming PC so im trying to learn as I go along.
 
ok, so i've got the card now and all seemed to be going fine, except the gfx card drivers keep crashing during crysis 2 making it unplayable. Is this most likely due to my PSU?
 
A 600W PSU should be okay. Make sure that the rest of you system is running stock speeds and disconnect any unnecessary components to reduce load. If you still have problems the graphics card itself may be faulty.

Don't forget that you have 10days to return any product purchased online if you are not happy with it for any reason. If you are not happy, or if you do not want to mess about changing PSU's, farting about with drivers etc, just return it quoting "DSR" regulations and the retailer has to provide a full refund.
 
600w is good enough mate.

I built my friend an i5 2500k system with a gtx580 and 600w PSU and he's been playing the witcher2, BF BC2 and crysis no problems.

Did you clean out the previous cards drivers before installing your current 580? If not that could be the cause of the problem, like the others stated you have the DSR if you still have problems.
 
No I didn't clean out the drivers. My CPU is overclocked, but don't really wanna slow that down as it's an i3. What's best way to clean out the drivers? Will try that when I'm back.
Thanks guys.
 
I am also a little miffed, 600W is pushing it even with a reliable well branded PSU. Its possible you'll never get any issues but I would want at least 750W

ok, I thought 600W would be pushing it, which is why I started the thread, so im happy to buy a new PSU. Would anyone like to suggest a nice one about 750/800/850W, got about £90 to spend, can gather a little more if needed.

Neither of you have ever measure the wattage at the wall going in then.

No one with a SG07 mini-itx chassis that features a 600w PSU has any problems. At it's time of release it was rated to support both the GTX 480 and 5890, as such a GTX 580 is no problem.

Like I said my friend has a system like that and he has no problems, 600w PSU, i5 2500k OC'd to 4Ghz and GTX 580.
 
Ahhh ok then, well I'll try uninstalling all drivers, but it doesn't seem to be messing up with any other games. I dunno if any other games will push it as hard in DX11 so that probs doesnt help. I tried furmark and other benchmark gfx software, but the temps on the card only reach about 60degrees, when im running crysis 2, accorded to MSI afterburner they hit 70/71degress. makes amps is about 59 according to gpu-z.

I think my psu puts out 70ish max but im running and OC i3, 1 tb hdd, h50 cpu cooler, and a xonar dg soundcard.

Why? A 580gtx uses 244w under typical load. The rest of his system isn't gonna use over 300w for what he has.

I also ran an i5 2500k at 4.5ghz, 8gb DDR, 1 SSD, 2x 500GB raid 0 hdds and a 580gtx on a 600watt ocz psu and never had issues lol.

1. Typical load is not the same thing as maximum load - if you open up Crysis and it crashes that kinda defeats the point. Nvidia recommends 600 "minimum" - they're clearly going to list the lowest minimum possible - other retailers list higher minimum requirements. I infer from this that running 600W isn't going to be sufficient, for example it may mean that a brand new top-notch 600W will work, but one that's a year old may not.
2. Wear and tear - power supplies decrease in efficiency over time, I think it's something like 10% per year, but I've got no link to hand to back that up. Assuming you're not keeping the rig more than 4 years, I'd allow about 150W for this.
3. Futureproofing - less important but worth considering, if you replace the 580 in future you don't want wear and tear to prevent you from going for something with slightly higher power requirements - I'd allow 50-100W for this.

So it's 750 if you allow for wear and tear, which you basically have to.
And 850 if you also allow for futureproofing.

based on budget of £90 I stand by my original recommendation:

Antec TruePower New Modular 750W '80 Plus Bronze' Power Supply
£85.99 inc VAT

Nvidia are covering their asses, just use google and bing and you'll find plenty of people with a GTX 580 and 600w psu, many are using M-ATX or M-ITX systems to boot without any problems.

Hell many are doing it with a GTX 480, 5890 and GTX 590. All on a 600w PSU.
 
600w is pushing a bit close, I have a similer setup to you and my tower draws 500-540W when gaming (i measured it at the wall) I was hoping I could get another 580 but 750w is far off enough, 1kw for sli 580's IMO.

Drawing 500-540W at the wall is not the same as the output from the PSU.

If your PSU is, say, 85% efficient then the PSU is outputting 425-459W so a 600W PSU should do the job as long as it has a good amperage on the 12V rail(s).
