Dear Rodney aka 3DGameMAN,
May I ask what are the consequences of connecting e.g the CPU 8 PIN power connector to the motherboard while trying to jump start a power supply? Will the motherboard be fried?
"Jump starting" a power supply using a conductor between the green signal wire and ground is exactly the same as hitting the power jumper on a connected motherboard. All voltages warm up the same way.
However, if a motherboard is connected to the PSU, bridging the terminals at the power jumper with a screwdriver will also wake up the PSU.
Razear, not to be impolite, but the question was on whether having the PSU connected to the mainboard during a jump start would cause any harm. It sounded clearly like he already knew how to start it up. Please read carefully before adding to a solved issue.
Thanks eire1274, and yes, I already know how to jump-start a power supply. So going by your statement, even if one pin e.g the 8 PIN CPU connector is connected no harm will be done when the power supply is jump-started? If that's the case then thanks for answering :).
Exactly as I said, the mainboard will see a power on state. The PSU doesn't see this "jump starting" as anything different than a normal power on.
However, if you have an OS installed, remember that a fully equipped mainboard (with CPU, memory, video, hard disk) will attempt a proper boot, and you don't want that to happen.
