  1. The basic eGPU hardware guide (for Macs) (this guide will be continuously updated and improved to add and correct informations) (Please feel free to comment and help gathering informations regarding the hardware topic) Because of a lot of basic questions regarding possible eGPU hardware I will try to answer most of the questions in this thread. The AKiTiO Thunder2 is currently the mostly used enclosure to run an eGPU on the Mac and because of that a lot of informations will be based and for the Thunder2. This guide is a extension of Tech Inferno Fan general guides: http://forum.techinferno.com/diy-e-gpu-projects/7969-pre-purchase-faq.html http://forum.techinferno.com/diy-e-gpu-projects/2129-diy-egpu-troubleshooting-faq.html List of current builds and benchmark results: http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html GPU power basics: The power consumption of current graphic cards can vary between 60-350W. Because the PCIe slot can only offer max. 75W, the additional power can be gained from: - 6-Pin PCIe plugs = max 75W - 8-Pin PCIe plugs = max 150W The 75W for the PCIe slot are only provided for PCIe slot, which are designed to host graphics cards. The normal standard for PCIe slots sets the limit to only 25W. That is also the reason why some enclosures only have low power power supplies, because they are designed to only host „non graphic cards“. The possible enclosures: - AKiTiO Thunder2 - Sonnet III-D - OWC Mercury Helios (basically the same as the Thunder2, but with a better PSU. Unfortunately more expensive! - Netstor NA211TB Links: Sonnet III-D Sonnet - Echo Express III-D Thunderbolt 2-to-PCIe Card Expansion System 2014 15" Macbook Pro Iris + GTX980@16Gbps-TB2 (Sonnet III-D) + Win8.1 [MrHaPPyPiLLs] http://forum.techinferno.com/implementation-guides-apple/6689-2013-15-macbook-pro-gt750m-gtx780ti%4016gbps-tb2-sonnet-iii-d-win8-1-%5Bsquinks%5D.html http://forum.techinferno.com/implementation-guides-apple/8059-2013-15-macbook-pro-gt750m-gtx780ti%4016gbps-tb2-sonnet-iii-d-osx10-10-%5Bmark%5D.html AKiTiO Thunder2: AKiTiO Thunder2 PCIe Box | PCI Express Expansion Box with Thunderbolt 2 Interface | AKiTiO http://forum.techinferno.com/enclosures-adapters/7205-us%24189-akitio-thunder2-pcie-box-16gbps-tb2.html http://forum.techinferno.com/implementation-guides-apple/8581-2013-macpro-nmp-gtx680%4016gbps-tb2-akitio-thunder2-osx10-10-%5Bsedor%5D.html http://forum.techinferno.com/implementation-guides-apple/9821-2014-15-macbook-pro-iris-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-%5Bdschijn-2%5D.html http://forum.techinferno.com/implementation-guides-apple/8106-2013-15-macbook-pro-iris-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-osx10-%5Bevo*%5D.html http://forum.techinferno.com/implementation-guides-apple/7580-2014-15-macbook-pro-iris-gtx780%4016gbps-tb2-akitio-thunder2-win8-1-%5Bgoalque%5D.html The AKiTiO Thunder2 is currently the cheapest way to make an eGPU setup (link zu 1.Seite Thread) and can be ordered directly from the manufacture for 189$+shipping. The AKiTiO offers a physical x16 PCIe slot, which can host any graphics card. The Thunder2 itself is shipped with a 60W power supply and not enough to power any current graphics card. The Sonnet III-D is the easiest way to set up a eGPU, but also the most expensive one. It’s case can host long GPUs and with it’s 300W power supply it can also power the cards directly. In the original configuration the III-D has an additional 6-Pin PCIe connector to power mid range graphic cards. To get more PCIe connectors, the III-D has to be opened and additional cables have to be connected to the III-Ds PSU. The choice of the graphics cards: The Sonnet III-D can host long graphic cards, but is limited in the height and width of the cards. The graphic cards shouldn’t be higher than 2 slots and not wider than the reference cards of e.g. Nvidia. The AKiTiO Thunder2 can host any graphic card, if the case is left open and modified by bending the front section. But there is also a variety of small graphic cards that can fit into AKiTiO and enables to close the case. Still the selection of possible small GPUs is limited to max. a Nvidia GTX 970. Possible cards are listed here: http://forum.techinferno.com/enclosures-adapters/7205-us%24189-akitio-thunder2-pcie-box-16gbps-tb2.html Cards that enable to close the AKiTiO can’t be too wide and by that the choices are limited: - EVGA GTX 960 (the one fan version) - Galaxy / KFA2 GTX 970 Gamer OC - Inno3D GeForce GTX 970 ot 960 Combat / HerculeZ X1 (the one fan version) - Zotac GeForce GTX 970 without the fan shroud AKiTiO can be closed: AKiTiO can NOT be closed The choice of the correct power supply: In theory any power supply that can provide 12V can power the GPU. Currently there a two recommended kinds of power supplies: - PC PSU (like for regular desktop computers) - Dell DA-2 (an external power supply with 220W) Most graphic cards don’t need more than 300W and by that any stronger power supply should work. That is wrong! Especially when it comes to desktop PC power supplies. The power supplies need to provide that specific amount of power on the 12V rail, that will power the GPU. It also needs to provide the correct plugs to power the GPU, which are 6-Pin and/or 8-Pin PCIe plugs. Because of that it is crucial to know which PCIe plugs the GPU you want to use needs. E.g. GTX 970 cards need 2x6-Pin PCIe plugs which is only provided by PC PSUs with at least 450W. Modern cards like the GTX 900 series can change the current state of power consumption multiple times per second and even exceed the normal consumption. The Dell DA-2 is an exception, because it can provide 12V and 18A = 216W in total. This 216W can be totally used for the GPU and can even power an AKiTiO Thunder2. It is important to keep in mind that you HAVE TO use only ONE PSU for the whole system. Please don’t mix two PSUs in this setup, because that can cause ground loops and damage hardware. Using the Dell DA-2: The Dell DA-2 provides a 8-Pin plug, which has the same size as a 8-Pin PCIe plug. It is important to know that the layout of the pins and the pinout is different, so adjustments have to be made. An easy approach is to use 6-Pin PCIe y-cable, because they can easily be connected to the DA-2 with a bit of pressure. To make the DA-2 a connection or switch has to be installed between the remote Pin and any Ground pin. If soldering is an option you can connect all 12V pins to one bigger cable and all ground pins to one cable. If you are doing that, please use proper wires that are thick enough to carry such high loads! The Dell DA-2 discussion can be found here: http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html A ready to go cable can be found on eBay: http://www.ebay.com/itm/Akitio-eGPU-8-PIN-TO-2-x-PCI-E-6-PIN-super-low-profile-no-latch-1-x-BARREL-/261932428549?pt=LH_DefaultDomain_0&hash=item3cfc63ad05 Using a desktop PC PSU: To use a desktop PC PSU you need to apply the „paper clip trick“ to make the PSU start. Simply connecting all plugs and switching it on doesn’t work! PC PSUs are designed to start, when the User is pressing the start button on it’s computer. Because we are not going to use the PSU inside a computer, there is no switch and motherboard connected to it, to signal it to start. The paperclip trick is creating a short circuit between the remote pin and a ground pin on the 20/24-Pin ATX plug that would normally be connected directly to the mainboard. Alternative ways to power on the PSU are the use of: - a SWEX (ATX Power Supply Power-On Switch) - a Bitspower 20 PIN ATX Keep in mind that with the paper clip trick, the PSU will always be turned „on“ and needs to be switched on/off by using the switch on the back of the PSU or using a power socket with a switch. Powering the AKiTiO Thunder2 with an alternative power supply: The Thunder2 only needs 12V to make it work. So a desktop PS PSU or even the Dell DA-2 can be used to power the Thunder2. To provide power to the Thunder2 12V and ground can be directly soldered to the Thunder2s PCB. Another option is the use of a barrel plug to connect to the original socket on the back of the Thunder2. The barrel plug has to be connected to 12V and Ground of the used power supply. The barrel has to have this dimensions: inside 2.5mm (12V) outside 5.5mm (ground) A plug that doesn’t need to be soldered is a barrel plug with screw terminals. Here you just need to stick in the wires (without isolation) to make an electric connection. The barrel plug discussion can be found here: http://forum.techinferno.com/enclosures-adapters/8317-%5Bguide%5D-making-molex-barrel-adapter.html Using an enclosure/case to host big cards and desktop PC PSUs: There is a way to store all your used hardware in common PC cases. I created a thread with ITX cases that will allow you to store all the devices inside a case: http://forum.techinferno.com/diy-e-gpu-projects/8675-egpu-cases.html Please keep in mind that you will have to make modifications to the case in order to place in the AKiTiO Thunder2 PCB and the GPU together inside the case. There is a way to relocate the PCB away from the GPU: a flexible riser. Riser can be used to extend the PCIe port and connect the GPU in more ways. BUT Riser may cause problems: - degeneration of the signal - stability issues - no working setup This is because there are a lot of very cheap riser cables on the market with very poor quality. Powered riser have been a recommended in the beginning of the eGPU discussion, but are currently focused on causing stability problems. This is because of poor quality and cheap material used to moddify risers. These riser are able to power the AKiTiO through the slot and also the GPU. We strongly advice you to not use a riser, unless you really have to! We strongly advice you to power the AKiTiO Thunder2 with the barrel plug mod, earlier discussed! The checklist: - which GPU are you using? - has the GPU the correct size to be placed inside the AKiTiO or do adjustments to the case have to be made? - how many PCIe power plugs does the GPU have (6-pin or 8-pin PCIe plugs) - does your PSU of choice have all the required PCIe power plugs? - are you using just ONE PSU to power the enclosure and the GPU? - is the paper clip trick used to "power on" the PSU? - is the AKiTiO Thunder2 powered? FAQ: Q: What is a barrel plug? A: A barrel plug is a barrel shaped plug to power low voltage electronics. There are different plugs in size and the used voltage (12V or 19,5V). The AKiTiO needs a 5.5 and 2.5mm barrel plug. Q: What is a PCIe power plug? A: Because graphic cards need a lot of power, the additional power is provided by PCIe power plugs. The common plugs are 6-Pin (75W) PCIe and 8-Pin (150W) PCIe plugs and are mostly found on desktop PC PSUs. 6-Pin: 8-Pin: Q: What is a Molex plug? A: The most common Molex plug is the 4-Pin Molex, that was used in the past for HDD and optical drives. That plug can be found on Desktop PSUs. The Pinout of the 4-Pin Molex is 1x yellow = 12V ; 2x black = ground ; 1x red = 5V. Q: What is the paper clip trick? A: The paper clip trick a way to trick a PC PSU to start without using a computer or motherboard. Please keep in mind that using the paper clip trick requires a power consuming device to be connected to the PSU if it is turned on. DO NOT start the PSU without any device attached after applying the paper clip trick. Q: What is PCIe? A: PCIe is PCI Express („Peripheral Component Interconnect Express“) connection slot to electronically connect computer cards.

    220W Dell DA-2 AC adapter discussion

    @Halbertus A 980 might only work if it is a reference card. If you still want to go the 980 way I can help you find the correct parts in Germany. Beeing able to fit a small 970 card into the AKiTiO and closing the case will result in importing a cable from the US which come with a big price.

    US$189 AKiTiO Thunder2 PCIe Box (16Gbps-TB2)

    You could directly solder cables to the PCB...
  5. @DJMatrix-HU3 Better get a Nvidia GPU or look around for other builds if they did manage to get a 480 running stable. You need to get an adapter to transfer 12V from the PSU to the AKiTiO.

    220W Dell DA-2 AC adapter discussion

    I can't recommend using anything more powerful than a GTX 970/1070. A reference GTX980 was running as well for one user, but I am not sure if that was stable. A GTX980Ti, especially non reference ones will consume much more power than the Dell DA-2 can provide. And don't be fooled by the 220W output of the DA-2. The PSU can't provide that load for a long time. Also the TDP of GPUs is never a guarantee of how much they actually use.

    EVGA 1060 SC with a single fan. Maybe the Zotac GeForce GTX 1070 Mini will fit as well.
  10. Yes, but the linked speed will be PCIe 3.0x4 = 2.0x8 = 4GB/s. Still 1GB/s left for USB/LAN in theory.

    220W Dell DA-2 AC adapter discussion

    Seems good! But it has just 1x6-pin, if that is enough. That shop is funny, making a confidential sticker on the pinout so nobody could guess how to wire it. But 10sec google will bring you to page 1 here
  12. @ProtoW For that apps you should get a real Mac with a dGPU. BF4 and BF1 will not perform well on a DualCore!
  13. This is going to be a more hardware based guide, because I will switch from my large eGPU setup with an ITX case to an "all in the AKiTiO case" setup. A significant difference in size as shown in the spoiler: The software setup is going to "reuse" my current instalation of Windows 8.1 from this guide: http://forum.techinferno.com/implementation-guides-apple/8571-2014-15-macbook-pro-iris-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-%5Bdschijn%5D.html Other builds I made 3 builds until now: 2013 13" Macbook Pro + GTX970@16Gbps-TB2 (AKiTiO Thunder2) + Win8.1/OSX10.10 [Dschijn] 2014 15" Macbook Pro Iris + GTX970@16Gbps-TB2 (AKiTiO Thunder2) + Win8.1 [Dschijn] 2014 15" Macbook Pro Iris + GTX970@16Gbps-TB2 (AKiTiO Thunder2) + Win8.1 [Dschijn#2] GPU To achieve that I will switch my GPU from a EVGA GTX 970 FTW+ to a much smaller Galax GeForce GTX 970 Gamer OC (Galax is known as a different brand in Germany: KFA2). That GPU is so short it can directly fit into the AKiTiO case without any modifications. Cooling For better cooling I will remove the stock fans and replace them with two 92x14mm Noctua PWM fans. I ordered a Mini 4-Pin GPU (Female) to Mini 4-Pin GPU (Male) y-cable to connect both fans directly to the GPU (fingers crossed that the PWM signal is good will give me a low Idle fan speed). Case modifications I will make two big openings two improve the cooling. 2x92mm cuts on the left side of the case, right in front of the new fans. This cut will be covered with 2x92mm black fan grills. 3x60mm cuts on the top for a good and easy exhaust of the hot air. This will be covered with 3x60mm black fan grills. Power Supply I will use parts of an old Dell OPTIPLEX GX620, that I got really cheap from eBay. That parts are the 220W Dell DA-2 PSU and the male plug that the PSU can connect to. That plug was directly attached to the mainboard of the Optiplex and will give me the opportunity for a small plug on the AKiTiO case. The AKiTiO itself will get power from a barrel plug. I am not really comfortable to solder wires directly to the AKiTiO PCB, so I will try the barrel plug first. Currently my idea of routing the cable for the barrel plug is to route it through the GPUs ventilation slots on it's IO shield. Overclocking (or maybe underclocking) If stability is good with the stock seetings and the cooling will keep the GPU cool, I will consider a bit OC. If the stability isn't good because of the PSU and the cooling can't handle the heat without a lot of noise, I consider underclocking the GPU based on this guide: https://translate.google.de/translate?sl=de&tl=en&js=y&prev=_t&hl=de&ie=UTF-8&u=http%3A%2F%2Fwww.tomshardware.de%2Fhtpc-gtx970-modding-cool-quiet%2Ctestberichte-241708.html&edit-text= Progress (x) ordering all the parts (x) remove the stock GPU fan (x) attach the new fans to the GPU (x) tape the case and draw cutting and drilling positions (x) solder the cables: 6-Pin PCIe (x) solder the cables: barrel plug (x) solder the cables: power switch (x) cut the ventilation holes: top side (x) cut the ventilation holes: left side (x) drill the holes for the fan grills (x) cut the case for the fan (92mm in front is beeing partially blocked be the case structure) (x) cut the case 3x for the DA-2 power plug (x) glue the power plug into the case with two-component adhesive (x) cut the case for a power switch (currently planning to place it in the front, because there is no other good option yet) I changed my mind and will keep the switch inside the case. Not happy with any other solution yet. Pictures (Schalter = switch) Windows 8.1 installation Since I already had Windows 8.1 running with my previous eGPU, it was just plag and play.

    220W Dell DA-2 AC adapter discussion

    @loucountryman I can help, but the low profile PCIe plugs would make it pricy. Easiest way would be to get the angled adapter yourself and I would provide an adapter for the rest. For you that would just mean to plug them together. I like these flat angled adapter: http://www.ebay.com/itm/261391561885?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
  16. @ProtoW 4. in games? Not really.
  17. @ProtoW 1. First guess would be to connect the AKiTiO in the middle 2. Not sure if the TB display will eat your TB bandwidth, you could right and limit your setup 3. Some apps in which you can directly adress the GPU in the settings, yes 4. Problem is that new MBs will only support TB3 and the future of eGPUs in OSX is not 100% secure
  18. Yes you can, but use the original cable! And check online the pinout to make sure what is ground/12V. Fingers crossed that you didn't kill your AKiTiO.
  19. "SATA/PERIF" = bad (very bad)
  20. @ti_padawan Do not use Molex or SATA pins from the PSU. Your approach to use the 6-pin PCIe was good. It doesn't really matter what the pinout on the PSU itself is, as long as you use the original cable to get a male 6-pin at some end and can rely on that standardized pinout. Why does your drawing have Molex coming out of the 6-pin? Did you apply the paperclip trick to power on the PSU? Do NOT power on the PSU without any consumer. At least have a fan connected. Why did you connect a 6-pin to SATA? on the PSU side? That might have been the problem... SATA pinout is not ground and 12V.
  21. @ti_padawan Well... something must be wrong. First guess would be short connection or a 12V / ground mix. Hope you didn't fry any components. Hard to tell what you did, better post pictures or make a drawing.

    US$189 AKiTiO Thunder2 PCIe Box (16Gbps-TB2)

    Yes, better get a good PSU that will make it work for sure. In theory a 120W 12V PSU should work as well, but people had stability issues in the past with PSUs like that.
  23. Because I didn't follow the the latest developments for the OSX script... What is the current way to install a eGPU in OSX? Since the script from @goalque is discontinued, what is the alternative? I guess the script should still work for OSX 10.9-10.11, right?
