If the installation manual says you need it you probably need it.

An extra 4 pin molex is sometimes needed to give power to the CPU or graphics card. If you're using a standard ATX power supply there should be a few extra connectors there.

Do I Really Need It ?

Yes, you really do.
They changed the power supply specifications several years ago.
You need to upgrade to power supply to match the new mobo.

Always upgrade your PSU if you upgrade the motherboard and CPU, especially if the existing one doesn't have a 4pin connection.

You might also need a new PSU because it can't give your components the wattage they need in the first place.
