Recently I upgraded the old power supply on my main PC (which doubles as my digital audio workstation). The old power supply was still working fine (Corsair AX760), but since a power supply in my completely separate gaming rig was starting to die, I decided to move the AX760 into that rig and get a brand new power supply for the main PC.

I decided to try one of these new "digital" power supplies from Corsair. I have always been impressed with Corsair products (a bad run with some SSDs being the exception) and as mentioned, the existing AX760 was still working perfectly.

Corsair's new "digital" supplies - the AX860i and AX1200i have shown through bench testing to have exceptionally clean and precise power delivery. Ripple in particular, is very low and vanishingly low in the top of the line AX1200i.

I had wanted to go all out and buy the AX1200i, but sadly it was going to be a tight fit in the desktop style case, so I had to go with the standard sized AX860i.

I did not really expect much improvement in sound quality, but after giving it a couple of days burn-in, I have to say that I am incredibly impressed by how much difference it has made. The sound is cleaner, more crisp and smoother - not hugely of course but certainly quite enough to be noticeable even with casual listening.

So certainly if you are running a larger ATX style of PC, these new types of power supply would certainly be something to consider.

As far as I know corsaire buys theire power supplies from seasonic.

Well I'm looking for a PSU for my new build so thank you for posting the info.  Any other thoughts on these:

hmm
they seem to require software to run them?  I wonder if you really need to run Cosair's software.
