ATX power supply in an HP Slim line MOBO

[fallenapples]

I want to use my old 300W PSU for an HP slim line. I have purchased the 20-24 pin adapter. However I noticed there is an additional 4 pin connector on the PSU that reads 4+ as well as other connectors that do not fit anywhere on the slim line MOBO. Do I need to connect these or are there just common connectors that I need to connect?

There are a ton of different 4pins, so some pics here might help.

Are you trying to use an old 300w PSU in a newer HP?

The third picture is the power supply main. And the first picture is the MOBO I want to put the PSU in.

That 4+ connector is the extra 4 pins to make a 24 pin. So technically, you didn't need to buy the adapter. When 24pin was just coming around they made 20+4 ends so if you have a 20pin motherboard you could just detach the extra 4 and be done with it. You can even technically plug a 20 pin into a 24 pin without consequence as the extra 4 pins are to control power saving features on the board.

The picture on the end is the case extras like USB, Firewire, front audio, ect. I can tell you right now one of those is going to be plugged into the white header in the first picture marked F-USB.

The pins will not fit in the new MOBO

All 20 and 24pin connectors are the same, and the others are also universal. If they aren't fitting, you're doing something wrong. If the board uses a different standard, chances are it won't work right.

I had to get an ATX to Micro ATX converter.

I had to get an ATX to Micro ATX converter.

Which shouldn't have been necessary like I said before.

They would not fit without it.
