  2. thanks :)
  3. A high quality 450W PSU will run the GTX 760, the key is in your 12v amperage. Check your PSU label to make sure (it says) it can supply at least 32A on the 12v combined, if so you can try to run it. Depending upon the PSU, if quality I would personally attempt it.
    Be aware though that if you start to have stability issues or the PSU is running loud, you'll want to get a more powerful PSU in there
  4. Will a cosair cx 500 (500w) be enough for this build
    I5 3470 quad
    Msi gtx 760 2gb
    500 gb or 1 tb hdd
    Cooler master 281
    8 gb ram
