Hello all. I'm reading about the DSP "The revolutionary AXi Series PSUs are the first desktop PC power supplies to use digital (DSP) control and Corsair Link to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX760i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS® Platinum Efficiency, and clean, stable power." What I wonder is why would I need to adjust anything ? You're saying extra efficiency so that model is really more efficient than the 20 bucks cheaper version ? Also I had a question I read on some french forum some guy say some of these PSU's got coil whining issue, I wonder, can you even RMA a PSU that does coil whining ?? It's really annoying.. my PSU died not long ago and using my old one, which now I remember why I changed it it does coil whining ! I really would like to get noone of this stuff, plus I kinda need new PSU anyway since that PSU I'm using now is only a 500w, and I with that PSU it will more future proof.
