Hey. I'm currently using this PSU, Hiper 580W HPU-4M580 SLi Certified ATX2.2 PSU for my rig: Asus M2N-SLI deluxe, Athlon X2 3800+, XFX GeForce 8800GTX I'm looking to upgrade the mobo and CPU to a Gigabyte GA-EP43-DS3P with a Intel Q9550 and was wondering whether this power supply will still cut it with enough head room to OC/overvolt a little. I'm happy to install a second PSU to power my HDDs, DVD-RW and lighting but I'd like to keep the CPU, GPU and M/B all powered off the same one.
