Computer won't recognize hard drive after installing new power supply

[IvyTheLeopard]

I recently installed an EVGA 500B power supply. I finally got it to get past BIOS but after that, it does not recognize the boot drive at all.
Specs-
EVGA 500B power supply
Sapphire R7 265 Dual-X
i3 3330
12 GB RAM
1TB HDD boot drive

Try with a different sata power connector.

Trying a different Sata cable does nothing. The CD drive works though

 

[mlga91]

Sounds bad, try reconecting the sata cable that goes to the motherboard, or swap it with the cd drive cable.

Replaced the power and SATA from the CD drive and still nothing

Check your bios if everything is correct.
If it still stand on your Boot Drive hdd. And check cable's if they are well good in and might turn off psu and on and see if it helps as well.

Is the drive even shown in bios??

Go to the boot tab on the bios to see if the drive is showing there.

It is not shown in bios at all I believe I killed the hard drive accidentally by mistaking the +4 pin connection in the 20+4 with the 4+4 CPU power

It sounds like it, dont you have another old hard drive to give it a try?

Ended up killing the drive but I replaced it with a SSD. Works amazingly now
