This is where I plugged it into.
I used one of the 4 pin connectors I cut off ( The green one in your previous pic), connected the two pins and put heat shrink on them so that the power supply will power on when you flip the switch.  These pins are PWR_ON and GND.

Here the 8 pin to 6pin is plugged in.  The 6 pin side goes to the Akitio Node Board power connector.

I want to give everyone fair warning. I did this with an sf600 gold about 4 months ago. Now the PSU is clicking off randomly and needs to be switched off and then you wait for a click and then it will work for a random amount of time before clicking off. I have been using it like this for about two months with random switch offs. Every product has bad apples but this one seems to have a bit of a track record of failure. Even the Platinum if you look around has reports.  I also read the in depth review of the platinum. Basically the improvements are just in efficiency not in reliability. The same design issue exists  

I even added an external fan to push more air through it. 

If you google this PSU with the word “failure” you will see I am not the only one. The speculation is that it just doesn’t like the repeated load switching of powering just a GPU. Maybe it would be better with a baseline CPU/MB load. 

I bought a Evga 650gm and I’ll be installing it today. Ideally it would have been the Seasonic SFX but it is not SFX it is SFX-L. The evga has poorer reviews but that is due to efficiency reasons. I really hope this one lasts.

I went ahead and did it. Every time it seems I need to do it twice. Those screw heads seems like they strip easily. Lost two of them. 

So if anyone knows the sizes please post here. I want to change them all out with new screws. 

The EVGA 650GM didn’t seem to work with the paper clip mod at all. I thought it was DOA. 

It turns out it comes with a “tester” in the box. This means you don’t need to do the paper clip mod. The tester does it for you. However it means you need to attach the huge 24 pin modular cable to the PSU and then attach the tester to the other end. This means a bunch of unnecessary cabling. 

The SF600 also required unnecessary cabling in that I had to draw power for the Node Pro board using adapters that converted peripheral power to GPU power. 

Overall it’s a bit cleaner but I would have preferred it just let me use the paper clip mod. It seems it has a switch associated with having the 24 pin cable plugged in. It doesn’t seem to want to work without it plugged in. I would have preferred the tester be male and just plug in directly to the PSU. Instead it is female and needs the cable plugged in. 

Otherwise it’s working great. The fan runs and puts out some amount of heat. 

The SF600 barely ran its fan and I suspect that was the problem. It would just overheat and shut off. Maybe putting that fan profile solved noise complaints but now the unit is unreliable. This is all speculation. But those are the differences I noticed. 

Maybe you could argue it is more noise but really if you have a 2080ti in a box air cooled, it can never be quiet. I have two 180mm fans blowing into the side of the case. They do reduce the need for the GPU blower to turn on. The whole thing ends up quieter. But true “quiet” requires at least AIO. 

If they had designed the internals tighter by moving the card as close to the side panel as possible maybe a radiator could be modded in. Then again the heat coming off the back of the card being too close to the EGPU board wouldn’t be great either. It’s so much heat there is an argument to put another fan on the side panel (not the mesh side - the solid side) to blow right on the back of the card. It’s so much heat that Nvidia could have put a finned backplate there. Not just a flat aluminum plate.

I attempted this with an Enermax Revolution and it doesn't turn on when connected.

OK, here is a very clear recommendation. Against this particular mod. Do not do it. Like sxr71 I had the issue of the PSU switching off. But let me tell you step by step.

First, the OP was correct about soldering an adapter and not using an off the shelf one. At least half. I ordered an ots-Molex adapter with the Corsair, and that one started melting and short circuiting, causing the whole thing to shut down. Nothing broke, but it smelled weird, and the adapter went into the trash.
I then soldered an adapter from the supplied modular cables, I also modified the huge Motherboard-cable and just did the paper-clip trick by soldering and heatshrinking two cables together. What no one tells you is that the paper clip thing is something you need to do permanently, not just once. So the paperclip 8or whatever you chose to use) needs to stay in place.

That worked for a while, until yesterday the PSU just switched off. No indications, nothing. It is running now, so it must have been a heat issue.

I now ordered an SF750, and will see how that works. The SF600 is going back to amazon. Sad, it is nice and quiet, especially with the Noctua fan I have in the enclosure, too. But switching off in the middle of a game is not good.

So, do not do this mod with the SF600. It DOES have issues, and they are not funny.

[EDIT]P.S. Same goes for the SF750. It will not ramp up the fan fast enough and thus shut down under high loads, which means the Akitio will just turn off and the monitor go black. Very nice.[/EDIT]

Not sure what sunstarfire was doing to get all these problems. My modded Node Pro has been running flawlessly with the SF600 for the past year and a half. It has powered a Sapphire R9 Fury Nitro, an Asus GTX980Ti Strix and a Palit GameRock GTX1080Ti with no issues. It even survived getting shipped halfway around the world in a crate with the GTX1080Ti installed.

Whatever issue people are having with the PSU replacement is tied to the execution of the replacement, not the Node Pro or the SF600.

I eventually bought a Node Pro and plugged a (Strix?) Vega 64 into it and it worked perfectly with the default PSU. Also the Geforce 1080 Ti works perfectly with the Node Pro.

The Node Pro is the best eGPU box on the market, "shame" on Intel for bullying the superior eGPU boxes by declining them eGPU certification for having a daisy chain connector. Akitio confirmed to me in person that the latency bandwidth etc. is the same between a Thunderbolt PCIe expansion box with daisy chain (doesn't get eGPU cert) and with (does get). They use two different chips, don't remember their names right now.
