We use quite a few MW psu’s in my company because they offer a good trade-off between performance and reliability. The one issue though during design that always comes up is conducted EMC. If you have any noise on the DC (e.g. from a CPU clock) it will go straight out to the AC side. We usually (now habitually…) have to add some form of common-mode filter on the AC side.
