Is it safe to add a big capacitor in parallel to a power supply
I have an application which uses a 1000W standard PC power supply, drawing continuously around 300W.

Can I connect a capacitor to a power source directly?
The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully it will come up
What happens when a already charged capacitor is connected to a power
You show the power supply as a battery. Most batteries, both primary and secondary, can absorb current in the reverse direction. The capacitor will discharge into the battery, the rate depending on the internal resistance of the battery plus the 10K resistor.

6 Frequently Asked Questions about “Where to connect the power supply of spiral capacitor”
How do I connect a capacitor to a lab supply?
The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully it will come up OK with the capacitor there. Lab supplies generally seem to do fine.
What are the components of a capacitive power supply?
Full-wave bridge rectifier circuit. Voltage regulator circuit. Power indicator circuit. A capacitive power supply has a voltage dropping capacitor (C1), this is the main component in the circuit. It is used to drop the mains voltage to lower voltage. The dropping capacitor is non-polarized so, it can be connected to any side in the circuit.
How do you connect a capacitor to an amplifier?
Connect the capacitor in parallel with the power supply terminals of the amplifier. This helps stabilize voltage fluctuations and improve performance. Similar to connecting to an amp, connect the capacitor in parallel with the power supply terminals of the amplifier. Ensure proper polarity and insulation.
When should a capacitor be connected?
It is fine to connect them when the output voltage of the supply and the voltage across the capacitor are close to each other. If they are not close to each other, you may get a spark at the moment you connect them. The spark can suprise you with the amount of energy it delivers.
How to install a capacitor?
It can be mounted vertically, horizontally, or at an angle as per the design requirements. Connect Leads to Circuit: Insert the capacitor leads into the corresponding holes or solder pads on the circuit board. Ensure that the leads are inserted fully and securely.
Are X2 capacitors ul & ENEC compliant?
