Was wondering what would happen if there wasnt enough power to feed the graphics card. Does the computer freeze up or just shut off? I keep getting freezes while playing games with my 4850 and am trying to figure out the problem whether it be the graphics cards drivers or my psu. Any help is appreciated. Thanks.
 
I know you'll get a warning message if the PCI-E power connector isn't connected at all. I don't know what happens if it's connected but not supplying enough power...

If you post your system specs and your current PSU, it would probably be easy to determine whether the PSU is too weak. Most likely it's something else but it might be the PSU.
 
its a q6600 with an ati 4850. Antec 500W is my psu. Gigabyte EP43 DS3L motherboard.
 
I am running a shuttle sff cube witha 250 watt power supply, my original config was an amd x2 4800, 2gb ddr2, 2 1tb hdds and an ati 4850. When I would get into intensive gaming the computer got really sluggish and would just act weird.

I then upgraded my processor from the 4800 to a be2400, which was a 90watt part to a 45 watt part. Needless to say the difference is night and day, as the computer runs like a rocket, versus its old behavior with a "faster processor".
So to answer your question yes it will run, but may act weird when you put a load on the system. Those q6600's start to need lots of power the more you overclock them.
just my 2c tho
check out the power supply calculator here: http://extreme.outervision.com/psucalculatorlite.jsp
to get an idea of how much you really need of a powersupply.
 
My 4850 ran oddly in an installation that had a 9800GX2 in it previously. It crashed in Crysis Warhead constantly. When I got my GTX 280 from Step-Up, I had to do a clean Windows install to get it working right. A 500W Antec should be enough to run your system with room to spare.

Did you check temperatures in the Catalyst control utility, to make sure it's not that?

A 500w Antec is more than enough.

It goes up to about 65C max on load. I have alot of cooling going onto the graphics card. But ever since I turned off ati overdrive it seems to run better with the default speeds. Could that be the source of the freezing?
 
It definitely could be. This POS card I have here, even with acceptable temps in the 60 degree range with cooling cranked still blue screens if I OC the memory even a little bit.
