It's a Corsair SF450 less than 6 months old.
I'm sorry but I simply cannot accept your excuse, even if it is technically true that the Lyra cannot handle the amount of ripple.
Every other part of the computer, the motherboard, the drives, the fastata, the BPPC, the Bvision, your rapidroad, the ethernet card etc all work immediately and perfectly on this "high ripple". (Perhaps you know that Bvision in particular is famed for power related instability.) So does everything in a normal PC, if I use this PSU to power one.
Now if every other computer part on god's polluted earth works correctly with this PSU, the conclusion is that the PSU is not "high ripple". It is normal ripple, totally within expected behavior, and Lyra 3 demands usually low ripple.
But I will say that your answer is something I should've expected, you're famous for blaming every problem with your products onto other people's products, commodore, the user etc. Saint Jens can do no wrong.
