I'm talking about this accessory from EVGA
EVGA PCIe Power Boost
Many X58 based boards (maybe others?) experience power supply issues to the PCIe bus if you run more than one GPU card in them. Some manufacturers have added a molex connector on the mobo to provide the extra power, EVGA opted for an aftermarket addon, and even gave some away to people who had problematic boards. However, they are out of stock, and I can't seem to find anyone else making them.
I have a PCIe x1 "audio riser" from an older board that I think I could cut to make one of these adapters. What I'm looking for is some kind of map of the PCIe connectors, to know where I should connect the power wires into.

Where to begin?

The Audio riser on the older board is not PCIe of any sort, but an Audio Riser point blank. If you have a board with an audio riser, don't shove Video cards in it...even if you make it fit.

As with x58 power issues, I don't think that's wide spread in my wildest dreams. I think you're reading SPAM and asking spamtastic questions. Dude, wake up...that's 1999 and the Abit BE-6 has that riser and is not PCIe.

EVGA recalls are fixed by shit!

Could be possible though, I mean, look at AGP and AGP Pro :roll: . It's not impossible, but I do agree it's not quite so widespread as one might seem to comprehend. We also would expect that such issues would be resolved rather quickly with board revisions.

OK, I guess my error was in calling it a riser. It's actually an OEM sound board that came bundled with the mobo.

Second, it must be widespread, because I have two boards with the extra molex connector on them. While I don't disagree that EVGA did wrong with this "patch", it is a known issue. I am not having any current issues, and any new board *should* ship ready, ie with the molex on the board, or some other solution built in. I wanted the device to have, more as a troubleshooting tool. You never know when someone is going to ship an older version board that was sitting in the back of a warehouse.

I'm sorry I asked for help on an actual mod. Obviously, something other than "ooh, shiney! look how pretty I made this box" wen't outside someone's comfort zone. I'll leave now, and let you all get back to ready made, bolt on case bling.

AFAIK the power boost is only "needed" for some classy boards. Any board with the molex connector does not need the cord. From what i have read you dont need the cord unless you have more than two graphics cards, on the mobos that have the problem. I have never read a post that said it fixed a problem, so I dont really know what it does still other than provide clean power...

I believe what you are looking for can be found here. You want to note that PCI E only uses 12 and 3.3 volts and if you look at the 1X, 4X, 8X and 16X the power pins are the same. So yes, with some effort and a little soldering you could make your own. Also, for what it is worth I would see it as a modification. :)

The adapter shown only provides additional 12 volt power which is all that is needed. Just make sure you get the pins right as to side A and B of the card.

Had a little trouble getting the site to open, but eventually did. Thank you, that is exactly what I was looking for. 8)
