Power supply

mlum · 06-11-2008, 12:18 PM

I have a HP Pavillion 780c and the power supply fan doesn't work. I bought a 300watt replacement and notice that the original unit has a 3 connector plug, 1 green wire and 2 black wire, that is plugged into the mobo. My replacement unit doesn't have that connector. What is this connector for? And do I need it?

That connector is for the internal fan of the original power supply. The new power supply has the fan connected internally.

when replacing you should have used the oppurtunity to upgrade to higher wattage

I did some research and found that it's a video connector. Do I need it?

The original unit is a Hipro HP-A2007A3, HP P/N 0950-4106

can you post a picture of it

It's a P7 connector, does that help?

I took a picture of it so how do I post the picture? I looked at the mobo and it has PS fan where this connector plugs into so it looks like it's for the fan. But what is a Video connector? I looked on Ebay for the exact replacement and it says that the unit comes with an HP video connector also besides the usual connectors.

the p7 is a floppy drive power plug,some video cards require one of these to be plugged into the video card
a p4 plug is usually the extra power plug to the m/b about half inch sqare with 2 black and 2 yellow wires
