Charging a high voltage capacitor with power supply. How exactly?
Will an excess voltage (measured at the source) break the capacitor before actually charging it? No. The capacitor will break once it charges up past its rating. Therefore there must be something to limit the input voltage to the capacitor. For this a voltage divider is a good option. If not, how does a typical HV source react to the situation?

How to Charge a Capacitor
How to Charge a Capacitor. Charging a capacitor is very simple. A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply.

Capacitor Charging/Discharging Circuits
Capacitor Charging. When a capacitor is connected to a power source, such as a battery, it begins to accumulate or ''store'' charge. This process is known as capacitor charging. The power source provides a potential difference across the capacitor''s plates, causing current to flow. This current then accumulates as electric charge on the plates.

Do capacitors automatically release their energy over time?
The capacitors on your PC are unlikely to be able to harm you simply because the voltages are so low.

The result is the true power, which is the power lost or dissipated in a circuit, typically as heat, being zero. But a small amount of total power is lost because the capacitors are not perfect. Reactive power (P r) is the rate that energy is either stored or returned from a capacitor. The unit for reactive power is VAR (volt-ampere reactive).
