Need help please

Um yes it does.

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)

Um, no. It doesn't.

AMD post stupidly high figuers to cover their asses.

My power supply is a standard size is that PSU you linked the same size?

Thanks

It's a standard ATX PSU

Not high enough based on the "quality" of many cheap PSUs out there

Indeed. It's the general ignorance about quality of PSUs that's caused them to do this.

If i try and run the 6850 on my current power supply and it isn't powerful enough, will it damage my pc or just shut down?

Thanks

That would be because the 7970 is on a smaller gpu die, 28nm v 40nm on the 6850 .

The 7970 takes at least an extra 100W of power than a 6850.

That depends entirely on the hardware inside the psu.

It could shut down gracefully and work fine later, shut down and never start up, make some noises before giving off a little spark and dieing, or it could spark spectacularly and fry everything in the pc.

Oh btw I would put money on the dell's psu being the cause of death for the 5770.

Not worth the risk for taking all your other components with it.

I ran 5770 crossfire on my 500w PSU. I'm now running a single 7970 on it. If you get a good PSU they can go over their stated wattage.

True, but that means they'll be operating at inefficient levels

@Gav_88 I suggest you take a reading from the wall from a system with a 6870 in before posting such nonsense.

So, no it doesn't.

Sorry i should know better than to suggest people follow the manufacturers recommendations.
