I have had my CX750M running my fx-6300 overclocked to 4.5Ghz and my dual r9 270x running in crossfire for a few months now. I'm starting to get concerned that I'm maxing the PSU out and that its going to kill itself and the rest of the computer if I don't change it to a higher wattage and more efficient PSU. Do I need to get a new one or is this PSU not as maxed out as I think it is? If I do need a new one, any suggestions?

Specs:
Fx-6300@4.5Ghz
ASRock 990fx killer
8(4x2)Gb ddr3
Dual r9 270x
CX750M

I can't even tell if it is because when my computer turns on, it sounds like a jet taking off! XD

I'm planning to upgrade it once I upgrade to a new CPU and Motherboard in a few months
