Using a resistor to provide load on the power supply. *updated*
kagem:
Ok, got a jpac and since there's no jamma board hooked up to the power supply, I figured I would use resistors to provide load. I was just wondering if using two 1.0 ohm 10W 10% Wirewound Resistors wired in series would work? I was then planning to use a case fan on the 12v+ rail to help cool down the resistors.
I'm trying to use these resistors since I can easily get them at radio shack. If they have better ones that I can easily get, then please let me know. Thanks.
**Update**
I went ahead and tried it out and it seems to work just fine. I had it on for about 30 minutes and the power supply didn't blow up or turn off so I guess it's ok ;D
Tips if you want to do this:
Make sure you wire the 2 resistors in series and not parallel. Also they do get hot so keep them seperated and away from anything that can get damaged. I attached them on top of an old cpu heatsink with cable ties and wired a 12v case fan pointed at them. I'm not sure if this actually helps or not but I don't see how it can hurt.
The resistors come in a two pack from Radio Shack at $1.79 Catalog #: 271-131

It would make more sense to just disconnect the AC from powering your power supply.
Or if you want to be neat about it, add in a second AC toggle switch.

Yeah, I'm still debating which way to go, but main reason I want to keep the powersupply hooked up is because my monitor gets power from it, and this way I can easily pop in a jamma board if I wanted to.

Wait, are we talking about a power supply or the AC distribution block? I've never heard of a monitor that can run off DC voltage (unless you've got one of those mini LCD screens...?)
