US$7 mPCIe eGPU adapter [PCE164P-N03] (inc NGFF/M.2)
► US$6 [aliexpress link] for 6-pin (PCIe)
(best to use with 220W Dell DA-2 PSU)
As appears in the Buyer Guide -> mini PCIe tab along with known issues and other pre-purchase questions.
- At US$7 it much more affordable than a US$39 EXP GDC & doesn't require power stabilizing ferrite beads either
- uses a x16 slot to hold the video card, though mPCIe only has x1 electrically wired
- does reliable Gen2 signalling, something that EXP GDC has been patchy at
- Has a ATX jack, DC jack and 6-pin PCIe input power version to supply the 12V/75W slot power
- has no 8-pin Dell DA-2 PSU input, though 6-pin PCIe version of this adapter can use this: US$3 Dell DA-2 to PCIe splitter
- no delay circuit to bypass a black bootup screen, though EXP GDC's PTD delay switch for that is unreliable anyway
- short 60cm interconnect cable. May requires a US$2 USB 3.0 100cm extension cable (male-female) as used in the video below, successfully at Gen2 speed, to make it usable. Or extension cable options are presented at the bottom of this post.
- round USB 3.0 cable cannot slide under underside panel openings as the flat HDMI cable used in EXP GDC can
- when using a ATX PSU(eg: 4-pin molex version) it requires jumpering the GREEN+BLACK lines on the 20/24pin connector as shown to switch on the ATX PSU
- there is no expresscard version of this adapter though eGPU.io user @diyman created his own expresscard adapter for it here
Successful implementation videos with this adapter
- Lenovo E531 + [email protected] by inxftw (comprehensive)
Youtube video of it in action with an Acer 4755 under Win10
Mateus, the first video creator below, may submit a future implementation guide using this eGPU adapter. He's using the aforementioned blue USB 3.0 extender cable in this video with reliable Gen2 signalling.
NGFF (M.2) version
Also at < US$10 pricepoint, there is a newer PCE164P-N06 PCIe with SATA, 6pin and ATX input power connectors along with a different interface mating adapter (NGFF.M2). It's also been added to the Buyer Guide -> M.2 adapters.
Longer or flat cable options
The supplied, somewhat inflexible round and short 60cm cable is something this solution could improve on. Here are some longer & flatter options found with web searches.
1. This eGPU adapter's mPCIe/NGFF end looks to be using a mini-B USB socket.
2. The supplied cable has no markings to suggest it's USB 3.0 spec but has operated at up to Gen3 (8Ghz) speed here.
3. A shorter cable has a better chance of running at Gen2 or higher link speed. A longer cable has signal attentuation.
4. A flat cable may thread easier beneath your system and results in a physically stable system if sitting it on the cable.
A longer Gen2 compliant cable
For users wanting a longer cable rated at Gen2 link speed, there's a US$2 100cm USB 3.0 Superspeed mini-B round cable.
Flat cable options
No USB 3.0 versions were found. These USB 2.0 spec ones may be problematic with Gen2 link speed with a shorter cable more likely to have Gen2 success.
|US$3 35cm flat cable
||US$3 150cm flat cable
Please provide cabling feedback to this thread
If you go ahead with this cable purchase, please provide thread feedback so we know what works.
I ordered one with a 6 pin power connector & implemented an eGPU with it. Details at:
2012 15" Lenovo ThinkPad Edge E531 GT740M + [email protected] (PCE164P-N03) + Win10
My plan is to set up rx 560 with it. But before I run out and get it I'll test it out with en9600gt on Lenovo E531, if of course I am successful in spoofing pci id. Hopefully your software will help..
I highly recommend this generic mPCIE compared to EXP GDC when it comes to GEN2 signaling base on my experience. Its CHEAP and very RELIABLE! I am currently using this to replace my GDC EXP..Tnx Nando for the video and info on how to set-up on this. The major issues here are: A.how to fit the thick mini-usb port under the panel of the laptop and B.how to power -up the PSU as shown on the video, otherwise everything is perfectly fine.
spopovich, thank you for the feedback. I too was under the impression the core functionality of this eGPU adapter (glitch-free Gen2 functionality) is superior to the EXP GDC that costs nearly 7 times more. A sore spot was lack of Dell DA-2 PSU input which is now linked to in the opening post. Thank you also for the heads up. I've add using the paperclip trick to jumper an ATX PSU.
As we have as yet no implementation guide on using this eGPU adapter, would you like to submit one start the ball rolling with this eGPU adapter?
@Bjorg, the 6-pin version of this eGPU adapter takes a PCIe plug as input from your power supply to provide the 75W slot power required. Your video card may then have it's own 6 or 8-pin PCIe plugs which would also need to be connected to your power supply to fully power the video card once it's inserted into this Generic x1-to-x16 extender eGPU adapter's PCIe slot.
Any idea if ExpressCard USB 3.0 adapters like this carry a PCI-E signal as well as USB? If they do then this $7 adapter may just work with ExpressCard 2.0 laptops as well.
Here's what Wikipedia says about the EC-USB 3.0 connection:
The ExpressCard 2.0 standard was introduced on March 4, 2009, at CeBIT in Hannover. It provides a single PCIe 1.0 2.5 Gbit/s lane (optionally PCIe 2.0 with 5 Gbit/s) and a USB 3.0 "SuperSpeed" link with a raw transfer speed of 5 Gbit/s (effective transfer speed up to 400 MB/s). It is forward and backward compatible with earlier ExpressCard modules and slots. ExpressCard 2.0 products were expected to be in the market by late 2010.
USB 3.0 SuperSpeed compatibility is achieved by sharing the pins with the PCIe link. An inserted card signals which mode should be used.
There is not as yet an expresscard version of this eGPU adapter
@ ybodhanya, that ebay-linked expresscard adapter converts PCIe to USB.
To use this eGPU adapter with an expresscard requires just a passive rewiring of expresscard to the USB 3.0 mini USB pinout they are using to tranfer PCIe signals. I have not seen the expresscard that mates with this adapter. It would be good if they made one as it seems this adapter has better electromagnetic noise suppression than the significantly pricier EXP GDC that requires ferrite beads as a fix.
This adapter insted of the one you mentioned for Mining because the one which you said is not sold in India.
@Mayur, the adapter you've linked has a x1 PCIe riser/extender with a x1 PCIe end. This is for use on a desktop system's PCIe slot and not suitable for your Lenovo G500s notebook. Instead, you require a mPCIe ended adapter to use in place of it's wifi card.
