I just built my system today and couldn't get any of the drives to power up unless the cables were plugged into the peripheral connectors on my new EVGA Supernova 1300 PSU. Nothing plugged into the SATA spots on the PSU will power up. This is keeping 6 of my drives out of commission, and those are ones that have some important data on them.

Has anyone heard of this before? How often does one got a bad PSU of this level straight from the box? Am I missing something that is keeping me from accessing these drives?

So your saying the power supply is of a modular cable type.
One where you can choose what set of cables to use depending on the hardware in your system.
And you are saying that when you connect them to your Sata drives you in fact get no power at all from the cables from the PSU to the drives them self. 108 W on the 12v single power rail should be enough to power a large set of hardware in a system.

If the case I would presume the PSU is at fault, the only cause as to why it would not work.
Is if there was a short in one of the cables used, being a large capacity of 1300W PSU it will, or should have a lot of protection circuits built into the PSU.
It may be the case that one of the circuits has failed, and prevents the PSU from...

Rma your PSU if it does not work as expected. After all it`s what the RMA is there for if the fault appears after it was factory tested and becomes Doa to you.

BTW: it`s a very nice PSU looks great !.

Yeah, looks like I will have to do that. It's depressing that I did all that and have to return the power supply.

I did power it all off and see that I can see the other drives if I unplug the modular connector from the SATA slot and swap it to the peripheral slot. It is really annoying and I had hoped I missed something simple.
