Todos são bem-vindos, os especialistas em hardware são preferidos a esse respeito: MOV ( Varistor de óxido de metal ) não está presente na PSU ( Corsair CS850m ), existe a necessidade de um estabilizador? Ele diz proteção contra sobrecorrente e sobrecorrente, mas assumindo que não é verdade sem MOV.

The necessary parts for a proper EMI/Transient filter are two Y and two X capacitors, two coils, an MOV (Metal Oxide Varistor) and a fuse. Very briefly an MOV is a voltage-dependent resistor that protects the PSU/system from voltage spikes coming from the power grid.
However, especially in low-end PSUs, manufacturers omit some components in order to save money. Usually the first to be left out is the MOV. If your PSU does not have an MOV in the EMI/Transient filter then you should always operate it along with a surge suppressor or a UPS, otherwise a spike could damage permanently not only the PSU but your system too.
The EMI/transient filter in PSUs is always placed before the bridge rectifier because, in this position, it also suppresses noise coming from the bridge's diodes (yes, even diodes produce noise, especially when they're being turned off).

An MOV is a voltage-dependent resistor that protects the PSU and system from voltage spikes coming from the power grid. If your PSU does not have an MOV in the EMI/transient filter, then you should always operate your system with a surge suppressor or an uninterruptible power supply (UPS). Otherwise, a spike could permanently damage not only the PSU, but also your system.
