Hi all, Yesterday I took out my 8800 GT & installed the Sapphire 4890 OC. It runs at 901/1000 factory settings. I have an Antec 650 watt EarthWatts with 2 PCI-e 6 pin power connectors. This card has a 6 pin & 8 pin socket for juice. I wasn't sure what to do & in the card's box are 2 6 pin adapters :bang:so I figured if thats what they gave me I'll just use my 6 pin ones on the PSU & see if it grenades. The card is installed this way & running fine so far. I haven't noticed any stability issues yet. I played GRID for 2-3 hours last night & it ran like a champ. Grid was the only game on my 8800 GT that my overclock wasn't stable with so I figure its loading the card pretty well. So my question is I guess, am I supplying too little juice to this card? And what's a good way to test it? If I upgrade to Win 7 soon & I start using more DX 10 stuff could I have stability issues then as the load is added to the card? I did run that Overdrive thingy to see what kind of overclock the card could handle but I got tired of waiting for it & cancelled it with 961 on the core so far. I have read that sometimes the Overdrive option isn't available if power seems to be any issue somewhere earlier. But thanks for any thoughts on this.
