Is it secure to turn off the power supply after shutting down?
No worries, PSUs behave like your laptop power brick—you usually disconnect them when they're not in use. The same applies to desktop PSUs. Everyone mentions high inrush currents, but it really doesn't matter. Components are built to manage these spikes. An 85Ampere inrush is still far below what actually occurs, and these spikes are temporary. Components are well-designed for such events. Even laptop power bricks tend to handle more current spikes than PSUs, and most don’t include NTC features. Conclusion—no problems, you can safely disconnect your PSU from the wall.
That's exactly what I do. No point wasting power unnecessarily. I switch off (at the mains) any computer and monitor after I've finished using them for the day. If I'm just nipping out to the shops, I shut them down, but don't always switch off at the mains if I'm going to use them when I get back.
Before leaving on a 4 week vacation, I switch off (at the wall) or unplug my broadband router, fibre PSU, both hardware firewalls, all SFP+ network switches, computers, monitors, TVs, HiFi amps, antenna preamp PSUs, DECT phones, etc., etc. That's 200W+ saved at $0.33 per kWhr, or roughly $50 when away from home for 30 days.
