While taking about PSUs, I have a CX430 in my rig. I know @bowei006 really doesn't like them but at least it didn't explode! I should probably go with some Seasonic deals and get a different PSU. While tapping the PSU it sounds really unassuring with its cheap-ish "dink, dink" sound.
EDIT: My rig barely used power. (FX-6300 and GTX 750)
The question is which CX430 do you have?
The new ones use another OEM. The old ones were rebranded SeaSonics and were amazing. New ones are awful.
