Aurora R2 Power Supplies

I own the Aurora R2 (P55).  I am looking to upgrade the power supply from the 525W stock, to something that can handle 2 medium quality graphics cards.  I saw that there is an 875W upgrade that's guaranteed compatible with the harness (so that I don't have to replug and rewire the case, I just plug and play), but I saw a lot of people putting the 1000W-1100W PSU's from the Area-51 series into the Aurora-R2s.  To do this would I have to replace the harness as well? It looks compatible but I wasn't sure if the pins lined up the same way at the connector. Anyone know about this?

Yes the Aurora 525w and 875w use the same harness.

I think a "single card solution" works better in the Aurora. Better cooling and no CFx or SLI problems to worry about.

Re: Aurora R2 Power Supplies

Thanks for the prompt replies, Installing the new PSU looks like it would be a breeze if I went with the W299G (875w), Can anyone confirm if the wire harness for the R622G (the 1100W T7500 PSU) is the same for the W299G (875w).  

If I went with the "single card solution" I would be fine with the 875w by far, but If I could keep the 2 cards cool, I would like to have them (especially since they come with Crisis 3/Bioshock) hence my considering the t7500 from the Area-51 series.
