Re: My 5 year old PSU okay for a video card upgrade?
Using anandtech's bench tool and comparing a Radeon 6850 to a 7870 shows about a 10% increase on loaded power usage with a better than 50% improvement in graphics speed.
You will be just fine.
Even though it is true that powersupplies do wear out and loose efficiency and max power output such a small difference in power draw is not going to be that bad. In fact with the new video card being that much more efficient, if you are going to be running with the same graphics settings as before your total power usage will go down not up.
Your total power usage is still going to be about 300 350 watts max significantly less than the max the power supply can provide.
