I have a computer that I pulled from the trash. The original power supply is dead so I plugged in one of my own. The motherboard has an 8 pin CPU connector and then right below that has another 4 pin connector. The original power supply has the necessary plugs, but mine does not.
By plugging my 8 pin connector into the motherboard and leaving the 4 pin socket empty, I did successfully power on the computer and boot into the BIOS. Confirming that is was the old PSU.
I'm wondering if its actually going to draw enough power to matter or not? The CPU says its a intel core 2 quad clocked at 3GHz.
