PSU Failure after installing new HDs

I just bought 2 WD640AAKS drives and added them to my system last night. I had a 150gb and 74gb raptor and removed the 74gb one to use in another machine. I basically took one of the corsair sata/4pin connectors and hooked it up to all three drives (2 sata power connectors and 1 4pin one). After I booted I got the "DISK BOOT FAILURE" error after posting. I then tried each drive and they all seemed to be completely dead. They made no spin up noise, weren't recognized by BIOS. I even tried them on another system and all of them failed. I tried my old 74gb raptor alone and it seemed to work okay.

So my question is did I just overload my PSU by running the 3 drives at once plus whatever else I have in my system? Was it putting all 3 drives on one power connector? Is my PSU still any good? (I post ok, just no HD/OS now). Do I need a new PSU?

On an aside, my PSU says it can support up to 8 SATA powered devices. But all the SATA connectors hook up to the PSU using a square looking 4 pin connector and the PSU only has 2 of those, and 1 has to go to the PCI-E vid card. So I only get 2 SATA connectors off the other one. Maybe I'm not making sense there tho :)

Your PSU has plenty of power.

Have you tried each drive one at a time in the other system?

Do the 74 and 150 work if you put them back in together?

I run four hard drives on my HX520 and have no issues. What you might want to mess with is your boot sequence and which HDD you want to boot first.

Disk boot error means the system is looking at the wrong drive for the OS. Go in your bios and make sure the correct drive is set as the boot drive.
