The title says it all, is it important to look at? if so what is sufficient? I'm asking because i RMA'd my psu and it has the same problem (a high pitch electricity, squealing noise). I heard it could be from the motherboard but I put off C1E, EIST and C3/C6, as suggested, no result.

This is the psu i have; http://www.mindfactory.de/product_info.php/info/p808837...

This is what i'd like to exchange it for; http://www.mindfactory.de/product_info.php/info/p808903...

There's a 0.5v difference on the -12v rail, that's why im asking.

Thanks :)

It's deprecated. I believe there were PCI that used -12V rail. Not used anymore.
