Status: offline 		I recently went to Radio Shack to pick up some solder for my dad and had no idea that there were so many different types. Even those that all had 60/40 were of a different diameter and weight. I don't know anything about solder or soldering, but know that I need to learn.

Is there one particular type of solder (silver, rosin, acid or lead free) and weight / diameter that is best to use when making these solders on the power supply and light bulbs?

What wattage solder gun is best to use?

Fine Electrical Rosin Core Solder - 60% Tin, 40% Lead, Diameter .050, "A Low Melting Alloy with Fast Acting Flux

If I want to use additional flux then I use:
Radio Shack Brand - Rosin Soldering Paste Flux - "For electrical and electonic applications"

Status: offline 		What solder I did use was just good ole 50/50 and the flux was oatey solder paste.
Flux the wire and get a melted glob on the gun and touch the wire, sucks right in. Put shrink tube over the splices.
Just what I had handy.
Now this is not fine electronic work mind you and nothing bad will happen if the joint fails.
Wouldn't use it on anything to important except a radiator or copper pipe.
Oh yes! There are a couple wire nut connections in there too.

[URL=http://www.cyberguys.com]http://www.cyberguys.com[/URL]

and enter part # 1130282 into the search box and you will see the Power Supply Load Resistor 1A

This unit comes with a 4 pin drive type connector attached to it so it could be used without any soldering needed.

You could also cut the connector off and solder the wires to the circuit board.

Either way the resistor has a heat sink on it with tabs that can be screwed to the case for heat dissipation.

Status: offline 		This is just a short comment on the Power_OK or Power_Good line. The ATX class power supply will run a series of self-tests to insure that all voltages are within operating ranges before allowing the system board to power up. When voltages are stable (usually 100 to 500 MS after power up), the Power_OK line goes active high and allows the processor timer chip to clear the reset line to the processor. If the voltage fails at any time on this line, the motherboard will reset and remain powered down until the line goes high again. On standard ATX PS designs, this line is gray and may be clipped off at the PS board level when converting the PS. The white wire is by standard -5V.
I have a page describing the conversion that I use for logic and robotics labs where I work that may be of interest.
