Okay so i just got a brand new Asus Geforce GTX 970 and noticed it has an 8 pin connector. Unfortunately, my psu doesnt have another 8 pin connector. Is it fine for me to use a 6 pin on it? Because i plugged a 6 pin and it was running just fine. Is it bad to run it off of 6 pins? Is it bad if i just run a small game that doest need much for run like fallout 3?
