Explanation
Older motherboards used a 20-pin ATX main power connector, while modern power supplies use a 24-pin connector. A 20-pin to 24-pin adapter is an inexpensive passive adapter that bridges this compatibility gap, making it the most cost-effective solution. Adjusting input voltage (switching between 115V/230V) does not resolve a physical connector mismatch. A modular power supply is more expensive and doesn't solve the pin count incompatibility. Rebuilding a failed power supply is dangerous, impractical, and not cost-effective.
