Sounds like when your old PSU blew up it killed both your motherboard or CPU, possibly both.

 

Good luck my friend. At least try clearing CMOS first.

Hey it turned on, boot device led is lit... Sorry to bother, what can my next problem be? I'm completely new to this.

your HDD/SSD is not powered/connected to the system.

Take everything out of the case and see what happens booting on top of a box, might be a short in the case

CX750m have a pretty high failure rate at work. No idea why, but the 650 and 850 tend to last much longer. I'd swap it out if you are still within the return period.

As for your problem, yeah, the hard drive isn't showing as connected or powered. If you assemble everything outside the case to make sure it all works first it'll be much easier to diagnose errors.
