[Coco] ATX power supply

[Steve]

In using a ATX power supply, must not over or under draw from all three 
power outputs  (3.3, 5 and 12 Volts.)

Most ATX power supplies need to draw 1 amp of current to work 
correctly.  This includes the not used 3.3 Volts in your setup.

In place of trying to wire up an AXT power supply, why not just used 
5/12 power supply that used to drive modern hard drives? On eBay, they 
are only $3.43 with free shipping.

True, it takes a few weeks to get here from Chine.  But $3.43 each, not 
bad.  You can get them a bit faster at twice the price.
