The Ultimate ATX Power Supply Mod With USB Charging Ports

Step 7 Update 9-22-2009

• I have redesigned the layout on the power supply.
• I moved the binding posts further apart so its easier to connect wires to them.
• And I made a nice labels for the front and top.

The power supply label in the zip archive was made in adobe fireworks and can be edited.

In order for the pdf to print at 100% size make sure to set page scaling to none in adobe reader.

The full sized label is 200dpi and should print out to be 7 ^1/8th inches wide.

did you wire the atx power on switch like so: http://ubuntuone.com/p/155G/

No, I've never seen it wired like that before. The green wire (ps_on) is connected to ground.

i have had it wired like this and had no problems but when i wired another power supply with ps-on wire to the ground it burned the power supply immediately. i read about "ps-on to ground" on wikipedia. i figured out the right way (ps-on to pwr-ok) by my self.

i just tried ps-on to ground on two power supplies. i gues we now have two ways to turn a power supply on: ps-on to ground or ps-on to pwr-ok. i probably short circuted that other supply that burned. :)

Some old dell power supplies used a different pinout even though the connector is identical.

all i know is i had it wired my way and it's been working for years and it still works.
no additional loads needed. it's not a dell but generic atx.

Very nice job. The only suggestion I have is to make it have molex and motherboard connectors in the back so you can just plug in any power supply withought taking anything apart. You could put the resistors with heat sinks in the wooden case and add a fan and air vent. Then it would be completely modular.
