Hi, have this model of firewire card. PE-101
It comes with extra 4 pin (fdd) energy suply and it is culprit of my problem. I need this molex for different things. So is it safe to remove this extra power suply from firewire card when I'm 100% sure, that only usage of this Firewire is capture from camera? Camera has of course its own power suply.
I think it is safe, but need to be sure for 100%.
Edit: it is in PCIe 3.0x1 slot. but it is mentioned in link i suppose
Thank you in advance.

Can be please moved rather to capturing thread?
If your camera has separate power then it is fine - 4 pin FW interface is unable to provide power to external device.
maybe there are splitter cables available?
AFAIK this 4 pin connector gives extra power to the extension board to eliminate too much power drain from pcie bus.
But l agree with pandy that if your camera has it's own power supply it will be alright
Ok. Thank you Pandy and Jan5678
As usual I was unclear. I have FW with two 6pin outputs. And FW has suply from PCIe and from floppy disk suply (4pin) <- and I want remove this.
It can be confusing, that i talked about 4pin fdd at 6pin output FW. But I got it. It is safe to remove it.
But I'm sure you get it right, when question was probably shroud in fog.
Thank you very much!!!
So I will remove it without any consequence. But find out it is working lately, all cassettes are already captured.
See you and have a nice day!

Well, not sure why you wish to remove Molex fdd power like connector from your card but for sure 4 pin FW doesn't provide anything above data - to provide power to external FW devices a 6 pin FW interface must be used.
Glad to read that everything work OK for You, thx and have a nice day too.
In short, and to close this thread. I buy bit expensive PSU from corsair 80+ gold that has two conectors to power supply GPU. But provide just one cable 6+2 pin. (can coast 5 cents) the price for PSU was about 100+ dollars. And now I need reduction molex - 8pin or 6pin it takes two molex conectors and I have only 4 in total. Also I need more fans another molex reduction. So have to find someone somewhere. And this feeding firewire seems to me be best. It should go smoothly without it. That is end of story.
Thanks for help all.
Can be closed.
already solved. But don't understand PCB traces. It is ordinary molex, ocupied with reduction to flopy disk drive. It is used to feed FW with additional electicity. So I think it is ordinary molex as any other molex.
It is like here https://i.ebayimg.com/images/i/350852253454-0-1/s-l1000.jpg
According to virustotal it is clear, but do not inserted it as active link. It made itselfs.
Thank you again.

Ok, my point was that this Molex connector mounted on FireWire card is powered trough motherboard traces and PCI socket then card PCB traces itself - as such if you start sinking too much current there is risk that something may be corrupted. So if your intention is to powering not demanding sink then everything is fine. Not sure also if there 12 or 5V on this connector - nominally it can be 12V but 5V not necessarily. Hope now it is clear.
