Play Music from CD-ROM without Computer

Here is a trick which will play CD in the CD-ROM without having a computer. This will work for the older CD-ROM which had 3.5mm Audio out Jack and can play only Audio CD [some support mp3 but no other format] [Best works with Creative 52X Multimedia CD-ROM also had an Infra-Red Remote and lots of buttons for play/pause, stop, etc].
You will need :

• A CD-ROM with Audio Out 3.5mm jack.
• A SMPS [Old AT SMPS which had a power switch to on the supply unlike ATX which needs motherboard to power on].
• A power cable to power your SMPS.

How to do:

• Connect the CD-ROM with SMPS.
• Connect your speaker to the Audio jack of the CD-ROM or connect an amplifier for Bigger speaker, power it up, insert an audio CD.
• Rock On!!
