This build is a few years old and has operated well for sometime.
PSU failed today. Unit would not start and started looking and figured out why.
Now have by backup PSU in until I get a new one (850W)

My issue now is that it no longer detects my 2 storage HDD's

My SATA is configured as follows:

SATA1 = Samsung SSD Drive
SATA2 = WD Black 750GB HDD
SATA3 = WD Black 750GB HDD
SATA4 = ODD

BIOS 4801 (latest)
ACHI Mode

BIOS detects SATA1 & SATA4, just not SATA2 & SATA3.

Have swapped connections around, power, etc. Nothing!
Very basic setup, nothing fancy like RAID.

Keep feeling I am missing something simple.
Would appreciate any ideas.

Thanks

That I have done. Multiple times.

I think it is a setting somewhere.
Had SATA1-2-3 all hooked to same power cable at one point and SATA1 worked.
SATA2 is a different connector then SATA3 (Intel 6gb vs 3gb) so I do not think it is MB hardware failure.

Thanks
