My Dell 2300 Power supply has a 20 PIN ATX Cable Plug and a 4 wire plug which is: 12V (P4) What’s the difference or name differences between a power supply that has both the 20 PIN ATV Cable Plug & 4 wire Cable Plug 12V (P4) ? Some similar power supply’s has the 20 PIN ATX Power Supply Cable and Plug but does not have the other 4 wire Cable Plug 12V (P4) ? What is both called by name or what’s their different style names please?
I wanted to test my buddy’s pc power supply out on my older pc but my pc didn’t have or didn’t have a power supply that has 2 cables. The one pc of my buddy’s didn't have the 2nd power supply cable of the 1 4 Hole Plug with two yellow and two black wires and it smoked my pc motherboard, the plug was the same but voltages musta been very different.
Note: didn't have any Power Supply manuals or nuttn.
Wanting to learn more is why asking.
Please reply?
