G4 1Ghz Sonnet Encore Power cable

[haemogoblin]

I need some assistance, I'm trying to recreate the power lead for a Sonnet encore G4 1Ghz.

I have a diagram, but I would REALLY like to see pictures of an original cable specifically where the 8 pin lead hooks in to the 20 pin header.

Still looking for help with this

Cable appears in this video: https://www.youtube.com/watch?v=jZon3u91KBM

Looks like a pretty standard Y-splitter.

I have the zif upgrade as well and no power cable. Did you ever figure it out?

Yes, I’m currently building one

I've built one of these cables before:

The pinout for the card's power connector is as follows:
GND GND GND GND +5V +5V +5V +12V

Thanks for the pinout and sorry for bringing this thread up again.

I recently got hold of a 700MHz Encore. Unfortunately without a proper power adapter cable as well. Therefore, thanks to your pinout, I will try to build an adapter, so that I can run this card in my beige G3.

Is it a bad idea to attach such an adapter to one of the molex connectors meant for internal drives (HDD, CD, etc)? Probably it would be easier than adapting to the mainboard atx connector (regarding the number of pins on such a three ended adapter and regarding the sheer size of the ATX 20 pin connector, which would have to fit somewhere below the drive chassis with all the IDE, floppy, SCSI power and data cables already floating around at that place in the housing). And the 4-pin molex should have all necessary voltages available as well (5V, 12V, GND), doesn't it?

Or is the drive connector too weak from the power supply side, weaker than the mainboard connector?

Thanks for your advice!

The Molex Mini fit Jr. pins (Sonnet card) are rated for at least 5A each, and there are three of them. A single AMP Mate-n-Lok (4-pin internal drive connector) pin is rated for 11A. Granted, that 11A comes with a 30C rise, which is a little uncomfortably hot.

Realistically, the G4 is not drawing 75W, or even 55W, so you can probably get away with it and it'll be fine. There will be a higher voltage drop across your adapter, but the card is regulating 5V down to a lower DC voltage anyway, so it shouldn't matter. Just make sure it doesn't get too hot.
