I really don't know a lot about electronic circuts and why you would need this, but would this item be of use for safety or stability in a gridseed application using atx power supplies.?...

24-pin Power Supply Jump Start With Dummy Load +3,3V.

or is it a waste and potential fire-risk.  I have had "resisters" in my car stereo system that saw too much wattage and started to smoke.  No fire, but it stunk until it burnt out the connection enough.

Do you really need to run a load on the 3.3 rail when not drawing the load for "stable" power in most psus?   

Maybe just a cheaper jumper is all that is needed.  I just want to see what others opinions are... in case i am overthinking this.  I am not using a paper clip that can pop out.  I want that to be my last worry.
