While playing some demanding games on my 560ti my computer randomly shuts off, my guess is overheating? should i get a cooler for it? i took it out and cleaned it, but still does it, if i lower the graphic settings it will run it, but not when its on the optimized settings

Cpu i5-4670k
8gb ddr3
gigabyte z87-hd3 mobo

GPU's will always run pretty hot, so I can't determine that that's the problem.
Use a monitoring program such as Speedfan or Afterburner to check your temps while gaming.
If they're less than about 75-80C, that won't be your problem.

For your PSU, I'd try something like a Corsair TX600 or a TX750, those should supply more than enough amperage.

And yes, that CX600 should do fine, it spits out 46A on the 12V rail.
