As far as hardware goes, this is pretty much all you need, aside from possibly needing to open up the Akitio box to allow for larger cards.

Should just be a plug-and-play solution. The 8-pin end just plugs into the Dell DA-2, the DC barrel powers the adapter (Akitio or PE4L) and the 6-pin PCIe power connectors go to the graphics card.

Reversible, tiny, faster: Hands-on with the USB Type-C plug | Ars Technica I'm not exactly sure what this means, but here's to hoping it means any USB C device will be eGPU capable.

I was wondering if this would work with a PE4L system? EDIT: And another question- is it reasonable to get the 2x 6+2 pin version? Since 2 6pins are 150W (at 75W each) and the slot itself is another 75W, we're already looking at 225W which is close to the maximum the Dell DA-2 can provide.

I believe that USB Type-C 3.1 will support some form of PCI-e communication

According to Intel Announces Thunderbolt 3 - Thunderbolt Meets USB (At Last) regular passive USB C cables will only support 20 Gbps. You will need an active cable to achieve the 40 Gbps speed. Probably won't be cheap.

With G-sync also coming to notebooks, should be a good time to upgrade soon

TB3 seems pretty promising

This may be due to Gen 2 signaling instability. To test for that, you would either have to go into your BIOS or Setup 1.30 and set the slot to 1.1 speeds and run the same tests.

Well, that's strange. I just went back to the GPU I first tested the PE4C with (Geforce 8400 GS) and it just stopped working. The fan turns on but the D4 LED is lit permanently.

Alienware Graphics Amplifier for $179 @ dell.com - Slickdeals.net $179 is getting into the price range where it is worth looking into

I considered the possibility of hardware, but I always thought signal instability presented itself as a crash during a stress test

After more testing (including on fresh installs of Windows 7 & 8.1), I still haven't made any progress in getting 2.0 to work. When attempting 2.0, (whether by using Setup 1.x or using an earlier version of the BIOS where the default speed is gen 2) the GPU is listed in device manager and GPU-Z , but MSI Afterburner, NVIDIA Control Panel and any attached monitors are inaccessible. I'm pretty much out of ideas since it works fine at 1.1 and isn't reporting errors when attempting 2.0

Install the drivers. Right Click > Properties to view errors

12V @ 3A is 36 Watts 12V @ 12.5A is 150 Watts

Unfortunately, the MSI GE60 does not have a ThunderBolt port; the only TB-equipped laptops by MSI are the WS60 and GT60. Somewhat irrelevant now, but the 900 series gpus are TB2 (x4 2.0) capable as shown http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#post89707

Yup, tried that. The GPU will be picked up in device manager and GPU-Z, but not in MSI afterburner and I can't open Nvidia Control Panel. That's in Windows 8.1 Windows 7 decided to stop working all of a sudden no matter what I try (reinstalling drivers with driver cleaner, etc.) and the GPU goes in and out of device manager, even without attempting 2.0. So, there's still a lot of experimenting ahead.

I'll definitely look into that, but for now, I still need to do more testing. Taking a closer look at GPU-Z, I'm actually only running at x1 1.1 instead of 2.0. I've tried Setup 1.x and also running a gpu load and still no results yet.

Quick update on my progress. Dell Latitude e5420, i7-2670qm, PE4C v2.1a, 8GB RAM, GTX 570 running Windows 8.1 3DMark 06: 20862(can't get it to run with Optimus) 3DMark 11: 4968(4625 with Optimus) 3DMark FS: 3290 (2957 with Optimus) Can't get the gpu to be reliably detected, not even with setup 1.30. Sometimes it takes a few sleeps to get detected, sometimes it works on boot. The good news is that 1 of my windows 8.1 partitions can output video through the gpu now- before, doing so caused a black screen.

You could probably even get away with something like this 12V 12A AC DC Adaptor Power Supply Charger Plug for 3528 5050 LED Strip Lamp | eBay if you're willing to pay a little bit more for portability. The pins on the gpu shouldn't matter because the EXP GDC should come with the appropriate molex power cables, unless your gpu has 3 pin inputs (I've heard of 3x 8-pin inputs). No extra connectors are needed to use optimus; the video signal is sent back down the mPCIe/EC lane, which is why you see a small performance hit.

Hi nando, is your Akitio using the modification to supply 75W through the slot?

Just identify the ports on your monitor (which take a video signal IN) and the ports on your GFX (which sends video OUT) then match the two with a cable. for more info
