Sorry for my long absence, much other work in the meantime. @toxec: Only two 4700 mF capacitors because there're no more of them here, and a extra buy I'd no desire. Moreover several test runs and measurements have shown that they are sufficient. @Charly: Sorry, but my "Windows" are only for to let the sunshine in my rooms and look outside my house. On my Mac's only run OS X Greets seefew Mobil mit Tapatalk

i just know the ZOTAC GTX660Ti Amp!. Not 7xx nor 9xx. The 660 have a short PCB.. But the metal cage around the fans exceed the size. As i removed this cage it fits into the Akitio Greets Mobil mit Tapatalk

Oh, guys, a little crawl every day keeps you young and agile and it's as good for your Joints. But toe training also :D

It should. The PSU pulls up to 4A, the switch can handle up to 6A.

Hi Friends, I don't wanna start a new discussion about this PSU. But what is a power SWITCHing unit without a switch, i thought? Without further ado, i took a switch and installed it. And here's how it looks: While it is very tight in the housing, but with a little tweaking, you can accommodate the switch. The switch cuts both lines of the mains voltage, so it's ensured that even with incorrect house installation, the power supply is de-energized.

@bsohn: I've added a 2nd 4 Pin JST housing. While software setup i've used it for to power the Akitio itself. In the finished build it was initially unused. I've read threads here and found ba10s118's instabillity Fix. According to this and because i don't like any parts outside the Case i've searched a possibility to add this fix inside. Hope this answers your question Greets Added pic's of my computer desk and Heaven benchmarks in the first post.

Maybe a additional possibility for your frozen system from 6-13-2015. Yesterday it was a very hot day. I've figured out the following: during about 5 hours of 3D modeling only the TB PCB of the Akitio becomes very hot also, until the system freezes, while temps of GPU and CPU are in a regular range.

Thanks Dschijn! But one thing is not clear to me: Why the thread has been moved to "Provisional Guides"? My build of the Akitio isn't provisional or "a work in progress" it's already finished and works right properly with my MBP and MBA.

Hi there, at 1st i have to thank to that great Forum and all the members who helped and inspired me! some of you have waited long time, thanks for your patience. After several hours of soldering, drilling & painting i'm now proudly to present the results. Although it does not looks like it take many hours of work but due i´m highly visibility impaired(my viewing range is about 2“) some simple things take much more time, therefore sorry if some img´s are creepy. about the background why i build an eGPU / a GPGPU: I own a Macbook Pro 13“(Early2011 CTO), a Macbook Air 11“(Mid2011 CTO) and an iMac 27“(Early2011 CTO), all with Sandy Bridge i5 & i7. Also i have a 3D Printer and a 3D Scanner. For the most normal work their performance is quite sufficient, however, if more sophisticated models to be scanned or modeled, my Mac's poking often their performance limits. Because of i've no desire to spend a few thousand bucks in new Mac's, I decided to build eGPU / GPGPU. eGPU for my iMac & GPGPU for my MB´s. Hardware: Computer: Macbook Air11"(4,1, CTO, [email protected], 4GB RAM, 256GB SSD) OS X Yosemite 10.10.3 Macbook Pro13"(8,1, CTO, [email protected], 16GB RAM, 128GB SSD) OS X Yosemite 10.10.2 iMac 27"(12,2, CTO, [email protected](soon replaced by [email protected]), 32GB RAM 128GB SSD) OS X Yosemite 10.10.3 [*]GPU´s: Gainward GTX970 4 GB GDDR5 (planned as GPGPU with my MB´s) Zotac GTX660Ti AMP Edition 2GB GDDR5 (planned as eGPU with my iMac) [*]PSUs Dell DA02 (to use with GPGPU) industrial PSU 12V300W (to use with eGPU) [*]and of course: Akitio Thunder2 PCIe Box let's begin @first i've dismantled the Akitio to get only the PCB´s and do the software setup on my MBP. This step has been discussed in some Threads here several times, so I must do this not again? If you wish i can do that of course. (most of the Pic's linked to larger versions. Click on it for larger view) wiring on the fly for software setup next step: electric/electronic mods Description of mods: A: added Connector for 2nd Fan B: customized 6X2 PCIe connector C: to prevent instability added 2x4700µF/16V B & C have insulation of Kapton tape closer view to the current input i've bought a Dell Optiplex including the PSU DA02 on eBay, desoldered the 4X2 housing from the PCB, desoldered the jack from the Akitio's PCB, take some 2K-glue and solder the new connector to the Akitio. For the moment the Remote pin is soldered directly to GND so the DA02 is permanently on if it's plugged in. I've replaced the wires from my provisional setup from AWG14 to AWG10, this should be quiet enough next step: Case mods: increase the space above the PCIe for better cooling i´ve opend the front of the inner sleeve and inserted a second 60mm fan because of the black design isn´t my favortite design, i´ve firstly dismantled the housing completely and bring many many layers of argent and satin lacquer to the surface. Look&Feel is almost identical to my Unibody Mac's: isn‘t it? Despite of the second fan in the front, the ventilation was too low to cool down the GPU, when the housing is closed. What to do, i thought? As well as my top fav design is the Mac G5/old Pro i take my drill and drilled overall 1150 3mm holes. And this it is how it looks like after at least 6 hours of drilling and cleaning The software installation went very smoothly both with the MB’s as well as with the iMac. The MB's don´t have any problems during the operation. The used software recognizes the GPGPU and uses that also correct. With my iMac I have several small problems with the eGPU. I do not get it, not reproducible, times it aborts the boot process and restarts automatically times it aborts the boot process and remains frozen with a crossed out circle, times it boots through normally. When booted through normally, times everything is OK, times the screen settings where shaked up to settings i´ve never used. Today i've made a provisional setup with the Akitio PCB's only and my Zotac GTX660Ti Amp! There are much less problems during boot in contrast to the setup with the GTX970. Here some img’s of it: don't lol, because of i've mounted the Zotac cooler to my GTX970 i've added an Arctic Accellero Twin to the GTX660Ti, atm i don't find the given fan so i connected a 140mm Thermalright . So, that's it what I've made with the Akitio. and finally: Feel free to visit the album on flickr. There are some more img's seefew's aitAC at flickr WTH stands aitAC for? Simple desc: it means all in the Akitio Case, regarding to Dschijn Hope you like my build My desk, aitAC connected as eGPU to my iMac Two Unigine Heaven Benchmarks eGPU(GTX970) vs. dGPU(Radeon HD6770M) vs. Greets seefew

@martinm0: take a look at Morvs pic "egpuwiring.jpg". Instead of the paperclip (red stripe) you can insert a switch. There's no huge load on it so you can use a small switch and thin wires

May you'll take a closer look to the temps. My rooms are at the attic and during summer, temps rise often > 35° and more while it is winter temps below 15° in the rooms. Times i've worked on huge 3D models eg full body scan or engines (> 1 million polygon) my iMac works quite fine in winter but freezes during summer.

US$189 AKiTiO Thunder2 PCIe Box (16Gbps-TB2)
seefew replied to Tech Inferno Fan's topic in Enclosures and Adapters
Hi @ All, i'm a little bit very curious, and I'd like to try something, maybe someone can help me. I'm looking for the PCB layout and / or a Schematic of the whole circuit of the Akitio. Thanks forward Greets
