Floppy power to PCI-E card in DL380 G5

Edit:
For what you need, I'd really suggest trying a different sound card.

But if you want to see MacGyver...

I've needed to provide auxiliary power in various HP ProLiant 2U chassis configurations. I'm sorry you're working with an older G5 HP, but you have some options.

  • Pull power from internal or external USB.
  • Splice power from the PSU connection.
  • There should be a 4-pin or 10-pin Molex connector intended for the drive backplane bay and CD-ROM cage. You can tap that.
  • If you're really desperate, you can tap power from a SAS drive slot.

If you get an USB->Molex adapter, you can then add a Molex->Floppy adapter. This would also be required for @Gene's solution.

McGyver would not want to be a part of this.

Side note: A USB->Molex adapter would need to be an active part (e.g. with a DC-DC converter), as USB doesn't have a 12V rail which is needed by both Molex and floppy connectors.


PCIe power adpaters exist. For example: check out the Sangoma ST1 Power Adapter.
