Just wanted to get some opinions from those much more knowledgeable than I in working with power supplies.
I have a small ATX PSU for a mod that I'm working on (which I will post about when finished), and trying to decide on how I want to wire this up.
I know that a lot of people just wire the power on (PS_ON green) to the switch and ground that to turn on.
However, I know that some (or all?!) should have a small load to remain on.
For example, from an Instructable here (and found in other tutorials on creating up some lab bench psu conversions):
Do I need to add this? I would prefer not to if I don't have to....

step 5Power Resistor
Most modern ATX power supplies require a small load to stay in the ON mode. I added a 10 ohm, 10 watt resistor between +5V and ground to provide this small load. It is strapped to the back wall of the power supply, where it should get plenty of air flow
