Current draw through a A600 motherboard?
Does anyone have any figures on the max current that can be drawn from a A600 floppy power connector? or the one on a A1200 for that matter?
I have a floppy drive that says 1.38A, and I want to power an internal cdrom, compactflash and another occasional use cf card from the floppy connector... Not being electrically minded doesnt really help TIA Jason |

@pertinax
depending on your PSU, anything from 25 watts to 35 watts, from that you can venture the max amps on the +5v line, is around 3-5 amps depending on your PSU. A Laptop Optical Drive, around 1.5amps on the +5v A CF card on the IDE around 400ma (0.4amps) An accelerator can sap a whopping 2-3 amps depending. |

The on-board floppy power connector is rated at 2.5A max! Grab a 44pin IDE to CF converter instead the 40pin IDE converter. 400mA is not a huge amount of current, but if you sum all, there is more than 3A (floppy, CD and CF). BTW: even summing just floppy and CD, you'll get more than 3A. But I bet you never will use the two at the same time. Better safe than sorry! If you want a good spot to take power from, solder the wires directly over the original power connector (you need to know what you are doing, of course)... |

Thanks all for the replys... The floppy is not being used and has been removed entirely. There is now a cf adapter in its place, which will be used for occasional transfer of files from another machine.
Any other use for a floppy connector on a miggy, except for... well, for a floppy drive? I have an external to use IF the need arises. I currently have pin 1 jumpered off so the boot time is Sweeeeeeeeeeeeeett lol TIA Jason |

Yeah, I should have noted.
That's in "boxed" machines with both drives drawing directly from an ex-PC PSU PZ. |
