I recently got 2 580s from my friend and was excited to use them so I put them in, I had been researching for a while to see if my 700 watt psu was enough and people said I should be good, turned on the computer and instantly shut off. Tested the psu and the 12 volt pins are putting out 10. I ordered a new 850 psu and just wanted to know if the rest of my pc is okay and if there are any precautions I should take installing the new psu
