Im settin up a testin station in one part of my house and making the shed a car audio heaven.So I got 3 Power supplies, 1 has which colors are which voltage/wattage and the other 2 dont, i have a few questions.

1) Would they all be the same as far as which color does which?

2) What do i do, just cut the wires i need from the connectors and leave all the other ones in the connectors?

3) Is there anything else i need to know about them that is just random info?

Yes the colors should be standard across brands. For instance, black is always ground, yellow is usually 12V, red is usually 5v, green is the turn on lead. Simply ground the green to turn on any ATX PSU.

Red - + 5v 25A

Yellow +12V 10A

White -5V .5A

Blue -12V .5A

Orange +3.3V 15A

Purple +5VSB 1 A

I never have before. I have ran ATX PSUs for 12 to 15 hours continuous with minimal loads and never had a single issue. I don't know where it came about that you need a resistor to load it.

You don't have to build that, I just said that it contains answers to the questions you asked.

So if i ground the green it will come on, the one i already did has a switch so i just cut the green short and heat shrinked it. Do i need to ground it?

If your PSU comes with a switch, then you need to ground the green wire. If it doesn't have a switch, then you add a switch between the green wire and ground.

Btw ATX PSU's along with a cheap small amp and a cheap sub make great powered subs for home stereos.

If you need a lot of current available, why not buy a real bench power supply?

it work fine on low power application. run mine 24h/7 since around 1 year without trouble. 22amp line on the 12v so getting around 240watt max. It is way more than enough in a ht trust me
