Okay; here is your very own

A2-2000 On-Line Power Supply Mods Kit!

Swapping-in fat leads is, technically speaking, a pretty simple job.

You pop out the power supply, open it, unsolder old +5, +12, and Ground

leads, solder in the new leads, close and replace the power supply. The

tricky part is what hackers call the "mechanics".

First, #12 or #14 gauge wire is not very flexible. Getting stranded

wire (instead of solid) helps. Probably, #14 gauge is more than fat enough

for all three leads. One case where #12 or #10 gauge may be worth the extra

trouble is the +5V lead.

Use wires colored the same as those you replace. On the standard

connector, the first two leads are Ground. Almost always, these are black.

Next, there is a space, then, in order +5, +12, -12, -5.

Depending on the bother involved, you can unwedge the wire bundle

where it passes through the supply case and remove the three old wires

(+5V, +12V, and one Ground wire). Or, you can just cut away each old lead.

Leave the -5V and -12V leads and one Ground lead alone.
