The risk is actually more to the power supply...but quite often, when power supplies fail, they puke up a lot of overvoltages and other garbage. But if it's a Doepfer PSU3, those are pretty beefy and they're overspecced. Just rearrange your +12V load so that everything's a bit more load-balanced across the busboards...and actually, the evened-out load might be useful to lower other component stresses, such as the busboard filtering caps, etc.
One other thing I'd recommend would be to get one of Konstant Labs' 1 hp PWRchecker modules. They're conveniently sized, plus they do a bit more than just being an indicator that the busses are functional. Very smart little thing...and for US$28, they're a no-brainer if you don't already have some front panel rail voltage indicators.
