?? On Power Supply
All/Red,
Got my hands on a 450W ATX power supply. One thing I do not understand is about the load resistors on the 5V side. I picked up a 2 pack of 10 ohm 10 Watt Sandbars to use. Now, since it is a 450Watt PS, do I need to use both resistors? Do I put both in series with one another (on the one 5V wire), thus giving me 20 ohms? Where do the Power Good and Power on wires go to?
Also, do I really need to use heatsink compound to attach them to the side of the PS case? Or can I just use zip ties?
I appreciate your help. I would like to get this up and running so I can use my new triton!!

Connect Power good to + 5 volts also.

Not quite sure how to wire the 2 resistors in paralell to the 5V, could you explain Red, I would really appreciate it.

Hi,
Take your two resistors and lay them side by side, now twist the wire leads on each end together so that instead of 4 leads you now have two leads, now connect one of these leads to the +5 volt and the other lead to ground.
That's it

I use a 12 volt (#1157 with both elements wired) light bulb in my conversions, they seem to be a little better dissipating the heat. I bring them out the back where the wire bundles use to exit, auto supply shops have a socket that just fits.

Red, I don't mean to sound like an idiot, but I don't know what you mean by "both elements wired". Can you explain please? Sorry.
