Hi, I own a pair of A-51's & I've solved the psu swap problem; I can solve it for you too. I make master i/o harnesses in my spare time & have them listed on eBay starting at 34.99. I make harness kits for Corsair ax-1200 & 1200i, Seasonic x-1250 & Nzxt Hale90 1200w. I own my own cable sets as the material to make the harness out of so it matches your new cable set exactly & blends right in. I also use the real Foxconn A-51 m i/o harnesses & put the correct modular connector on the end. If you want to phase out your whimpy psu & do a real psu swap using one of my pre-built harnesses, find me on eBay: seller ID: Cass-Olay, or search: "Area 51 power supply cable". You can message me anytime through this site, eBay, or the Dell/Alienware forum regarding the purchase & install of my harness kits.
