Wanhao i3 ATX PSU Upgrade

This is an upgrade for the Wanhao i3/Monoprice Maker Select. My main reason for doing this upgrade is noise reduction. The built-in PSU is very loud compared to most computer power supplies, which are practically silent. I have a lot of older ATX power supplies that I no longer need, so this upgrade is a great opportunity to repurpose them. As an added benefit, the new power supply can provide power for additional components such as a Raspberry Pi running OctoPrint, 5V or 12V lighting strips, and other small accessories you may want to add. This assumes that you have already installed a relay for the heated bed. If not, please do that first before proceeding with this upgrade.
