If your computer with an NZXT H510i case and an ASRock B450 Pro4 motherboard is shutting down unexpectedly or is not receiving enough power, use this guide to replace the power supply.
The power supply is what delivers power to all the other parts of the computer and is one of the fundamental components in any computer. A faulty or damaged power supply can result in a computer shutting down unexpectedly, or can result in the computer not receiving enough power to turn on.
