If a new PCIe video card requires an 8-pin power connector, what is the least expensive solution?

1. Replace the power supply

2. Use an adapter cable connecting two 4-pin Molex connectors

3. Buy a new 8-pin connector

4. Use a hard drive power connector

The correct answer is: Use an adapter cable connecting two 4-pin Molex connectors

Using an adapter cable that connects two 4-pin Molex connectors to create the necessary 8-pin power connection is often the least expensive solution. This method takes advantage of existing power connectors found on older power supplies, allowing you to avoid the cost of purchasing a new power supply or specialized connectors. This choice is practical as many older power supplies still include 4-pin Molex connectors. The use of an adapter provides the required power without needing to modify the existing power supply system. It is a straightforward solution that does not involve the added expense of replacing hardware that might still be functional. Opting to replace the power supply may provide a more robust and powerful solution, especially if the current power supply doesn't meet other requirements, but this typically involves a higher cost and more complexity in installation. Buying a new 8-pin connector might imply acquiring a specific cable designed for this purpose, which could also prove to be an unnecessary expense. Utilizing a hard drive power connector could seem beneficial at first glance but may not provide sufficient power or the appropriate connections required for modern graphics cards, making it less reliable than using the adapter.
