Is there a need to power down the PSU after closing down the PC?
Hey there, just wanted to make sure you understand whether it's really needed to turn off your power supply after using your PC. Since I'm in a South East Asian country like Indonesia, my electricity is quite unstable (220-230V, but often drops to around 160V). This makes me wonder if shutting down the PC and power supply switch is necessary even when using a full-range 110-240V PSU. I'm concerned that unstable power could damage my components or the PSU itself. Also, should I consider using an AVR instead? Thanks!
Modern PSUs must manage brownouts effectively (input voltage drops). Even if it occurs when the PC is off, it shouldn't cause any issues. For concerns about power quality or high-end systems, consider using an isolated UPS or AVR. A double conversion, galvanic isolated UPS is ideal, though they can be costly and noisy.
Turning off the power strip or wall outlet should suffice, preventing the system from drawing power in a vampy manner. They still consume a minimal amount of power, which is why the system remains active after shutdown—this is standby power. I would also turn it off if I were you. Power surges can lead to early failure of components.

It seems the power can be cut off via a power strip or wall outlet, and an isolated UPS or AVR would also work. Thanks to both of you for the clarification and advice!
