So I have an old pc. I am slowly upgrading all aspects of the pc. I just the the gigabyte gtx 970 and I looked online and it said I needed 550w minimum, to power the card. My friend gave me a 700w psu it’s a thermaltake sps-630m. Changed everything out that I needed to. Plugged everything back in but it won’t boot up. I then out all the old stuff back in and the pc works fine. What could be wrong? Thanks I’m adv
