Last night my computer suddenly turned off all by itself. I tried to start it again, but nothing happened. I disconnected everything except the ATX power connector and the system turned on, although I didn't even get into BIOS. I found out by trial and error that if I didn't connect the 8 pin power connector to the motherboard, the system would turn on, but not even get into BIOS. I changed the power supply and now the system would turn on and let me into the BIOS. So far so good... apparently the PSU had died (Seasonic S-12 500W)
I still couldn't boot the OS, but then I noticed that my harddisks didn't spin up (two WD5000KS in a RAID-0 array). I disconnected the harddrives, put them on my desk attached to a new PSU and turned the PSU on with my ear to the harddisks. Not a sound, they are not even trying to spin up. I took a spare harddisk and tried, just to check the SATA power connector on the new PSU, and it started up fine, so apparently the PSU is good.
Now I can't find any other explaination, than that the PSU died and took everything on the SATA power connectors with it. However, I have the feeling that I'm missing something. I mean... It's a Seasonic PSU and it killed two harddisks at the same time (and left all other components working), despite the problem being with the 8 pin connector to the motherboard. It just doesn't sound right to me.
I tried removing the print from one of the harddisks and checking it, but it doesn't look like anything is burned on it. At least nothing obvious by looking at it.
Any ideas, suggestions, ...?
