OK to leave existing PCI 6-pin wiring installed when switching power supplies?

Probably a silly question, but I'm replacing this unit:

with this unit:

Is there any reason not to leave my 6-pin connected wiring in place in the case, and simply plug them into the new PS? If it's all standard, saves re-wiring the entire case. I'm simply fairly new to all this, and don't want to screw anything up...

Any other pointers?

Thanks, Joe

Oh, now that I look closer, they're 6-pin SATA connectors I'm looking at. (I'm talking about the end that plugs into the PS)

6-pin SATA on the XFX and 6-pin SATA on the EVGA.

Reason for replacing: the ball bearing fan in the XFX has worn to the point of being fairly noisey, and I'd hate to leave it installed fearing PS failure.

I actually chased down a supplier in china selling the 135mm fan, ordered one, waited a month, and received the wrong fan. Contacting seller only earned me the chance to purchase another one = don't think so. AND I had opened up the XFX in an attempt to lube the fan before realizing it was actually still under warranty. Too late now; AND the replacement they'd offer is not a tier 1, but has lesser quality caps.

AND, I had thought the EVGA is tier 1...

A couple evenings of reading here on Tom's landed me at the decision to purchase the EVGA :) Plus the MB is EVGA: it's like putting a Chevy engine in a Chevy hot rod ;)

So I had read a poster being rather happy placing it fan up (his, like mine, is bottom case mounted); the manual recommends placing fan down if an air vent is provided on the bottom of the case (which is the case with mine).

So that's the brain-twister: a vent in the bottom with factory filter in place: I have to wonder how much air really gets sucked in the vent, and how much actually simply gets drawn from the case. And since I'm not overclocking, I'm thinking the PS may spend the majority of it's time with the fan off, in which case the convection cooling seems like it would work better with the fan up...

But then, I'm pretty sure the team who designed it tested both orientations thoroughly.
