So about a week ago I put a GTX 770 in an older Dell computer, everything works fine but when I play some more demanding games (fallout 4, skyrim, gta 5,...) and everytime something happens in the game my system crashes. I tried reinstalling my video drivers (using DDU) but it has no effect. After doing some research I found out a GTX 770 requires 42amps. When I look at my PSU it says it can only deliver 18A on the +12V rail. I don't know if I'm reading it wrong because I don't know how these rails work in PSU's. I've put a picture of the label of my PSU below.
