I have a Xion 600W modular PSU and a Xion 1000W modular PSU. My problem is that they both love to turn on and off about 15 times before the computer can even POST... That means I have to wait an additional 2 minutes before I can use the computer. Any ideas?

It does sound like a psu problem, if you are comfortable with opening your pc then (remember to use anti static wrist band rubber matting etc) and remove the psu and give it a good dusting (as the dust does collect in on the fan and inside the unit itself (please be careful when working with this unit as it is a power unit and can be dangerous) put unit once cleaned back into the pc making sure you reconnect everything carefully. (if you are not sure rather take it to a professional as you can do some serious damage to your mother board and or peripherals. but this should give a few more boot ups ultimately you could replace it with a new PSU.
If it only comes on when you move the cables but not if you don't then one of the cable connections (pins) are loose or internally broken. Unplug it and check each cable/pin for any loose connections, bent pins etc.
You can start the PSU manually with a paper clip.
Remove the 20 pin connector from the motherboard, leave the four pin power connectors attached to your various drives (this will provide a load on the power supply when it start up (provided it is not faulty).
Look at the 20 pin connector with the connector facing you.and the locking clip to your left.
The fourth pin from the bottom LH corner should be a green colour wire and the next two wires (5th & 6th pin) should be black and next to the locking clip.
Straighten a paper clip and insert it into the 4th pin and into the 5th or 6th pin (ie connect these wires together). These wires connect to the front panel switch to turn on your computer. You are testing the power supply only and since it is not connected to the motherboard the computer won't start.
Now connect the power unit to the mains and switch on the mains, if the power supply is OK the PSU fan should spin up and your hard disk should also spin up. If nothing happens the the PSU is faulty.
You can test the +5volts and +12volts supply on a 4 pin power connector with a multimeter. The red wire is +5volts and the yellow wire is +12volts and the black wires are negative (ground). The voltage readings should be within 5% of these voltages.
There are other voltages to be checked +3volts, -5volts, & -12volts. but these are not as critical.
Try unplugging, then plugging back in the 20/24pin power connector. When you plug in the power connector, make sure the power supply is OFF and the switch in the back is OFF and nothing is plugged into the computer.
You sound like you know what you're doing, so I expect you've made all the motherboard connections(Same as the original PS).
Does the switch work when you test it?
If so, it sounds like the PS is DOA.
I've had bad luck with cheap power supplies.
