overclock will draw more power, your psu will already be at its limit running the card at stock clocks

Didn't understood... Why can't I overclock it within the safe limits?
Because ultimately, there are no safe limits.

you can always pick up a Sapphire 5850 Xtreme, same performance as a 6870, but cheaper. Might be hard to find in your area though since they were just a limited release card trying to sell back stock.

Well I used this calculator for the psu power comsuption and, with the cpu overclocked and some extra fans that I don't have xD, it recomends a 350watt psu. Mine is a 480 watt, pretty good Tt psu, so won't it be enough?

Reading up on PSUs will be good of you. There are a few types of PSUs. Those that have peak power and those that have continuous supply

His PSU is fine. My PC at max pulls around 550w and I have more hardware than he does. He will be able to OC just fine on that PSU.


I do recommend getting a card with Voltage controls though. It will make a world of difference when OC'ing the 6870.

I did the same calculation with overclock and its comes to 375watts. You are fine man.,...enjoy!

It's not a different type, it's a different rating.........
a decent 400w-450w would be FINE for that rig, however I'm unsure about that psu

FYI: The 6870 draws 250w at load.

So I read in a review

Quote:
Something else to consider is the fact that the 480 watt power level is what this model can do sustained. Many manufacturers will represent their peak loads as being the wattage level of their power supplies, but the Butterfly reviewed today can do the 550 watts peak, 480 watts sustained.

I think that PSU need to be changed just to be safe, the 6870, i think is nice i can play nice stuff @1080p on very high settings with my 5770, anyways get it if you have the money and start saving to change the cpu as well you may get the gpu bottlenecked, i know my X2 6000+ is horrible compared to your E7400 but i was getting the same frames as my 9600GT with the 5770 that i own right now, i change to the PII 955 C3 and the frames increased a lot.You have a P45 mobo so try to buy a Q9400 for example, that way you shouldnt need to change the mobo.
