You were asked if your PSU was an "i" series.
The fastest, ZERO cost, solution may depend on that detail.

If your PSU is 1200i search this thread for that number and look thru results of last week or so.
Or
Go to the Corsair website and look for "i" series software for PC and just try it.

This might be a link to the correct SW

I did not try it, no "i" PSU here.

There is a way to make the "i" series work that was posted recently .

YMMV
