So I spent an extra 3 hours messing my new build today to find out that my PSU was bad. I had ordered an EVGA 500 bronze. I inserted my old Antec Earthwatts 650 (http://) and it booted up fine. I am wondering if this 4-5 year old PSU will run my build okay or if I should reorder the EVGA? The rest of my build is as follows:
* ASrock z75 Pro3 Mobo
* Intel core i5 3470
* Geforce GTX 760
* 8gb Vulcan RAM
* 1TB Western Digital HDD
* Windows 8.1

Thanks!
